Re: multiple instances in win 7 -- any idea
Hi Charles, it is very easy to run multiple mysql instances and of different versions as well on the same server, including windows. You just have to download the .zip version, NOT the installer. The archive you get is basically a separate independent mysql instance that can live fully in its own directory. Unzip the archive/s in separate folders and create/copy the my.ini in the root of that folder changing just two parameters: ex: c:\mysql3331 c:\mysql3332 Instance #1 - file:c:\mysql3331\my.ini [client] port = 3331 socket = /tmp/mysql3331.sock [mysqld] port = 3331 socket = /tmp/mysql3331.sock basedir = c:\mysql3331 Instance #2 - file:c:\mysql3332\my.ini [client] port = 3332 socket = /tmp/mysql3332.sock [mysqld] port = 3332 socket = /tmp/mysql3332.sock basedir = c:\mysql3332 set the right paths and enjoy. you can quickly test if the server starts normally by going into each basedir with the prompt and running bin\mysqld.exe then on different terminals bin\mysql.exe -urootto login Cheers Claudio 2012/5/14 Shawn Green shawn.l.gr...@oracle.com On 5/13/2012 6:53 PM, Brown, Charles wrote: I'm trying to install multiple instances of mysql on windows 7, 64bit. 3hrs into the job, I'm not making progress.

Re: Here's an Idea for Re-Syncing Master and Slave During Production Hours without Interrupting Users (Much)
Hi Eric, At least with Maatkit, you get transparency. We make a concerted effort to update the RISKS section of each tool with each release, so there is full disclosure. Fair enough, but I still found the warnings a little too scary. A more complete explanation of the exact nature of the bugs and the exact circumstances under which I should be concerned about triggering them would have increased my comfort level. I've made a note to review these, because the ones I checked have kind of drifted from their original purity. I updated the RISKS section for mk-table-sync the other day. I checked it and agreed with you -- it didn't distinguish between cases where there is actually a risk, or cases where the tool would just refuse to work (which isn't a risk IMO). And it sounded ambiguously scary in a don't-blame-us, we're-avoiding-your-eyes kind of way because of passive voice. You can see my changes here: http://code.google.com/p/maatkit/source/detail?r=5269 I think that's a pretty realistic balanced statement of risk: you are playing with a powerful tool, so learn how to use it first. Thanks for the feedback! BTW, there's also a Maatkit mailing list that I watch closely: http://groups.google.com/group/maatkit-discuss - Baron -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Hi Baron, I'm the primary author of Maatkit. Awkward... :-) What can I say -- you could go buy a commercial off-the-shelf tool and believe the song and dance they feed you about the tool being perfect. There's not a single commercial software solution in our toolbox. We're big fans of CentOS, LVS, heartbeat, ldirectord, tomcat, MySQL, Xen, pureFTP, and more. We've been happy with the performance and reliability of all of our FOSS tools. I'm definitely not a Kool-aid drinker when it comes to commercial product marketing. At least with Maatkit, you get transparency. We make a concerted effort to update the RISKS section of each tool with each release, so there is full disclosure. Fair enough, but I still found the warnings a little too scary. A more complete explanation of the exact nature of the bugs and the exact circumstances under which I should be concerned about triggering them would have increased my comfort level. I think Maatkit is by far the best solution for live master-slave sync in most real-world situations.

Here's an Idea for Re-Syncing Master and Slave During Production Hours without Interrupting Users (Much)
Let's face it, sometimes the master and slave get out of sync, even when 'show slave status' and 'show master status' indicate that all is well. And sometimes it is not feasible to wait until after production hours to resync them. We've been working on a method to do an emergency hot-resync during production hours with little or no user downtime. What do you guys think of this approach? It's only for Linux, though... 1. Shut down the slave and remove its replication logs (master.info and *relay* files). 2. Do an initial rsync of the master to the slave. Using rsync's bit-differential algorithm, this quickly copies most of the changed data and can be safely be done against a live database. This initial rsync is done before the next step to minimize the time during which the tables will be read-locked. 3. Do a 'flush tables with read lock;reset master' on the master server. At this point, user apps may freeze briefly during inserts or updates. 4. Do a second rsync, which goes very fast because very little data has changed between steps 2 and 3. 5. Unlock the master tables. 6. Restart the slave. When you're done, you have a 100% binary duplicate of the master database on the slave, with no worries that some queries got missed somewhere. The master was never stopped and users were not severely impacted. (Mileage may vary, of course.) We've tried this a few times and it has seemed to work well in most cases. We had once case where the slave SQL thread did not want to restart afterwards and we had to do the whole thing again, only we stopped the master the second time. Not yet sure what that was all about, but I think it may have been a race issue of some kind. We're still exploring it. Anyway, comments would be appreciated. -- Eric Robinson Disclaimer - December 4, 2009 This email and any files transmitted with it are confidential and intended solely for my...@lists.mysql.com.

(1) innodb? It's an off-the-shelf application that uses MyISAM tables.

I think he's trying to say that this method wouldn't work for innodb, unless you copied files from an LVM snapshot, or something similar. I would say that it's very important to know why data is getting out of sync between your master and slave. Fixing those root causes would eliminate the need for this. There are cases where non-deterministic queries will produce different results, but that's what row based replication is supposed to solve =) There are ways to resync data that don't involve all this as well: Maatkit has some tools that compare data between servers, and can fix them with queries.

I would say that it's very important to know why data is getting out of sync between your master and slave. Ultimately, I agree. But since it's a canned application, getting to that point might be hard, and once it is resolved, new issues might arise. I would never have any confidence that the replication is solid enough to use the slave server for backup purposes. (Which, by the way, is the real reason I'm doing this.

Dynamic tables--always a bad idea?
We're trying to figure out how to design a particularly critical table in our database schema. The choices are to use a single large table or a series of dynamically created small tables. This table will receive the majority of traffic (queries and updates) in the database so it's a key part of the design. The data set means we're either looking at 1 table with perhaps 10 million records or 100,000 tables each with about 100 records. Standard SQL theory seems to say we should use a single table. It's more flexible and some queries simply aren't possible across multiple tables (or at least not efficiently). But in this case we're happy to live with reduced flexibility if it gives us substantially better performance. Early empirical testing with 100,000 records suggests the single large table becomes progressively slower to access as it grows in size (average access time goes from ~4ms/transaction up to around ~80ms for our test cases--MySQL 5.0 on CentOS). The multiple dynamic tables don't seem to have this property--access remains pretty much constant as you might expect (~4ms/transaction). So the question is, even given this 20x performance benefit are we still fools to consider the dynamic table model? Are we going to run into max-tables or max-file-handle limits or other problems that will eventually bite us? Or is this speed difference just an artifact of poor indexing choices or similar? Or are dynamic tables OK sometimes? Doug P.S. Here's the table in question: CREATE TABLE one_big_table ( rank bigint not null auto_increment unique, item_id int not null, user_id int not null, countsmallintnot null default 1, addeddatetimenot null, primary key(rank, user_id) ) engine=InnoDB; -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

We know that we won't need to do those sorts of queries except for statistical analysis which can happen offline (and for that we'll assemble the data back into a single table).

We're trying to figure out how to design a particularly critical table in our database schema. The choices are to use a single large table or a series of dynamically created small tables. This table will receive the majority of traffic (queries and updates) in the database so it's a key part of the design. The data set means we're either looking at 1 table with perhaps 10 million records or 100,000 tables each with about 100 records. Standard SQL theory seems to say we should use a single table. It's more flexible and some queries simply aren't possible across multiple tables (or at least not efficiently). But in this case we're happy to live with reduced flexibility if it gives us substantially better performance. Early empirical testing with 100,000 records suggests the single large table becomes progressively slower to access as it grows in size (average access time goes from ~4ms/transaction up to around ~80ms for our test cases--MySQL 5.0 on CentOS). The multiple dynamic tables don't seem to have this property--access remains pretty much constant as you might expect (~4ms/transaction). So the question is, even given this 20x performance benefit are we still fools to consider the dynamic table model? Are we going to run into max-tables or max-file-handle limits or other problems that will eventually bite us? Or is this speed difference just an artifact of poor indexing choices or similar? Or are dynamic tables OK sometimes? Doug P.S. Here's the table in question: CREATE TABLE one_big_table ( rank bigint not null auto_increment unique, item_idint not null, user_idint not null, count smallintnot null default 1, added datetimenot null, primary key(rank, user_id) ) engine=InnoDB; -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Best Idea On InnoDB Table for Pooling System
Imagine American Idol where users vote on their Idols Imagine that the system is using an innodb table... where INSERTING is very fast might be concurrent BUT inserting is done over HTTP and PHP (not enable multiple insert :(( ) Updating status for each data inserted is also very fast i mean everytime for each incoming vote we must reply the vote, so we need to update the state On the other side, we also need to count for each data real time What is the best configuration i mean from InnoDB engine it self for this High Concurrent Insert High Concurrent Update High Frequency on Select count(*) on table Thx -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I've optimized the main tables (the forums one and a few others) a few days ago. About index cardinality, I don't know what to tell you. For a few tables it is high, like for the vbulletin postindex (higher than 11 000 000) but it's absolutely normal for such a forum. And about explain, we've got a few hundred tables so i can't tell you much :) Thanks for your help, Julien Lavigne du Cadet. - Original Message - From: Victor Pendleton [EMAIL PROTECTED] To: 'Julien Lavigne du Cadet ' [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, July 26, 2004 3:06 PM Subject: RE: Slow server - any idea?

As far as I know, MySQL should be able to handle hundreds of connections on a single CPU box without degrading performance like above. You are completely missing the point. It is nothing to do with concurrent _connections_ it has to do with running concurrent _queries_. What you are saying is like well, if you can sit down and solve this equation in 10 minutes, why does it take you 40 minutes to solve 4 different equations? There is no magic way for the machine to do a hundred things at once on a single processor (assuming you don't yet have a quantum computer), they all get run for brief periods interleaved with one another. If you are running 4 at once, then each will only run 1/4 of the time. The box is working as hard as it can to process one query, do you think it should slow down how quickly it processes one concurrent query just so that number will change less if you have more than one? I'll repeat what I said before: a query that takes 600ms on such a machine is not a trivial query. If you real question is why is my query so slow then you should probably ask that instead of getting confused about why your machine can't do 4 things at once. P.S.

Idea to speed up multiple jdbc connections?
Hi, I would appreciate any help on this: I got approximate same timing on following two: case 1: create 1 jdbc connection and issue 4 queries sequentially case 2: create 4 jdbc connections and issue 4 queries via 4 different threads at the same time The timing is done around statement.execQuery(query), so overhead of multithreading can be ignored. I would think case 2 should be faster, but it was not. Any idea? Thanks a lot PS: the mysqld server 4.1.1a is running with 16 threads __ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

Hi, I would appreciate any help on this: I got approximate same timing on following two: case 1: create 1 jdbc connection and issue 4 queries sequentially case 2: create 4 jdbc connections and issue 4 queries via 4 different threads at the same time The timing is done around statement.execQuery(query), so overhead of multithreading can be ignored.

Re: Idea to speed up multiple jdbc connections?
Yes. The time I measure like I said is purely around statement.execQuery() call. Connection creation is not a factor here at all. My database has 1.64 million rows and 4 queries are all selects, which are identical in both serial and parallel cases. In serial cases: Query 0 took 590 Query 1 took 431 Query 2 took 461 Query 3 took 440 In parallel cases: Queryer 3 query took 1552 Queryer 1 query took 1632 Queryer 2 query took 1783 Queryer 0 query took 1923 I don't understand why in 4 concurrent connection cases (already created not included in the timing) it takes more than 3 times longer to exec. a query.

RE: Idea to speed up multiple jdbc connections?
Oppz! Sorry for overlooking your timing method. In this case, I believe if you run the query in four different machines at the same time, the statistics should almost the same as running four consecutive queries in the same machine. I believe the multi-threading implemented in the JVM and the OS is not parallelly the same!

Umh... if your queries are limited by some bottleneck on the server (such as, for example, CPU) then why would running them in parallel make it any faster? It seems that in the sequential case they are taking a total of 1922 (whatever those units are) while in the parallel case they are taking 1923. What this is telling you is that, in this case, a single query is able to fully utilize the resources (likely CPU given these numbers, although it is possible it could be disk) on the server. If a single query can fully utilize the server, all that adding more concurrency can possibly do is slow the total throughput down. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
New Idea
Hello again, After realizing the obvious implementation flaws, I thought of a new idea and again, would appreciate some feedback on the efficiency benefits. My last post involved INSERT vs UPDATE efficiency. Neither is going to be a directly useful approach. With 48k records and growing for just one table of 2, the dump time was significantly too slow. Here is my new idea. Instead of directly communicating with MySQL, how much more efficient would it be to write the same statements to a text file, and then fork a child thread to connect to the database, and read the entire infile at once? There is some optimization for this , in addition to which writing the text file should only take a few seconds since it's a strict out stream write. Obviously this would increase performance of the client which dumps the text file, and also give an intermediary level of preventing data loss, if the import didn't go for some unpredictable reason, the file could still be imported prior to restarting the application. Has anyone used this sort of method, does it pose any issues I haven't considered? I also realized I am running 4.0.10-gamma, precompiled for FreeBSD packages. I will be compiling 4.0.13 with linuxthreads to gain any benefits there as well. Thanks, -Shane p.s. I always find a last question. Off topic, compiled properly for each machine, would MySQL run better on a quad ppro 200 (IBM PC704), or a similarily stocked 2.5ghz P4 single processor system? Curious for expected results on a new development server versus production server.
Re: New Idea
how much more efficient would it be to write the same statements to a text file, and then fork a child thread to connect to the database, and read the entire infile at once? If I understand you correctly, this is addressed in the section of the manual to which I previously referred you. From said section: When loading a table from a text file, use LOAD DATA INFILE. This is usually 20 times faster than using a lot of INSERT statements. See section 6.4.9 LOAD DATA INFILE Syntax. would MySQL run better on a quad ppro 200 (IBM PC704), or a similarily stocked 2.5ghz P4 single processor system? Most likely the P4. I don't believe Pentium Pros support hyperthreading, which would actually allow the database tasks to be split between the processors. I may be mistaken, but I'm fairly confident here. A great deal of skepticism about the multi-processor Pentium systems, especially older ones, always stemmed from the fact that neither the processor or the OS (in the case of Windows) was capable of making full use of a multi-proc architecture.

Idea: Syntax help on command line
Hello
I use the mysql command line tool quite often and always wondered why
there's no feature that lets me quickly see the syntax of a FOREIGN
KEY or GRANT command. Now while browsing the source I found the
new syntax command in 4.0.12 and got the idea of implementing this
syntax help of myself.
What do you think of a client command:
mysql syntax select; (or \S or SHOW SYNTAX OF)
SELECT [STRAIGHT_JOIN]
[SQL_SMALL_RESULT] [SQL_BIG_RESULT] [SQL_BUFFER_RESULT]
[SQL_CACHE | SQL_NO_CACHE] [SQL_CALC_FOUND_ROWS] [HIGH_PRIORITY]
[DISTINCT | DISTINCTROW | ALL]
select_expression,...
[INTO {OUTFILE | DUMPFILE} 'file_name' export_options]
[FROM table_references
[WHERE where_definition]
[GROUP BY {unsigned_integer | col_name | formula} [ASC | DESC], ...]
[HAVING where_definition]
[ORDER BY {unsigned_integer | col_name | formula} [ASC | DESC] ,...]
[LIMIT [offset,] rows | rows OFFSET offset]
[PROCEDURE procedure_name(argument_list)]
[FOR UPDATE | LOCK IN SHARE MODE]]
Reference: 6.4.1 http://www.mysql.com/doc/en/SELECT.html
I managed to hacked a working demo in less than 10 minutes which is
simply a copy of the syntax function and which uses syntax() to pipe the
output of an arbitrary command back to mysql (of course it could be a C
function, too, but why the unnecessary burden and having it as seperate
program makes it useable standalone, too!)
This program could be a perl program which either has syntax definitions
hardcoded or, even better, is able to extract them from the docs.
A preinstalled html documentation could be prerequisite which has
two comments like !-- BEGIN SYNTAX: SELECT -- ... !-- END SYNTAX --
so that the syntax is easily extractable. Something in the kind of
cat /usr/share/doc/mysql/en/$1.html
could be enough for the first start, too.
The final stage would then be that this help command is called whenever
on presses e.g. two times tab after writing a command like a command
completition.
Any suggestions and comments?
bye,
-christian-

Re: FAQ hosting site (was Re: An Idea)
Yes, you need to specify the IP address that you plan on using for this process instead of the computer name. If you use Windows, chances are your using MYODBC or some other similar driver. Case #1: You setup a DSN in the ODBC area of the OS Case #2 You setup a DSN-less connection to your db. Case #2 has actually worked much faster for me. You can just put the IP in your connection code and off you go. Either way, you need to do this because the OS cannot resolve how you want it done. Just to make sure it is two NIC's that is causing your problem, disable one in the IP configuration area and give it a try. If you still cannot connect to your db, then something else may also be wrong.

I can't create ssh accounts for everyone, but we might arrange ftp Let's set up a PHP thing with MySQL. That's quite fast and easy to do. I could contribute some code. My suggestions (database design): 1. We need an authors table, and everyone who wants to be an author (contributor) can mail you, and you will set up accounts for these persons. The authors table will, of course, be used for database authentification / to update the admin pages. 2. For the actual content, we will need only one table, with question (varchar), answer (text), timestamp and a couple of id's that refer to other tables. 3. For the beginning, I would suggest we only have two more tables: category (installation, privilege system, ..., generally speaking, the main chapters of the manual) and difficulty (beginner, advanced, expert). _Not_ to be edited by the authors, to keep the FAQ smooth and simple. - We can make this more complex when necessity comes, with ratings, automated checks for double entries etc. My suggestions (frontend): 1. For end users, a very simple search. As Jim (JamesD) pointed out, Alkaline could do the job. Then again, Alkaline will search (and before, index) documents, and not databases. For the beginning, I would prefer just a simple input box for the search. 2. Output preferably as html files, i.e. nothing like index.php?cat=installationdifficulty=beginnersearchterm=windows, but rather something like /installation/beginner/windows/1.html.

RE: An Idea
alkaline has been around awhile. the model is similiar to mysql in that they have a commercial version that sustains them, and a free version that sustains the rest of us. there is not a doubt that its better than the php script you refer to below... http://alkaline.vestris.com/docs/alkaline-faq/af-general.html#AF-GEN-WHY its claim is very high speed searching, partial word searching, multiple remote site indexing and spidering etc. good for high speed results on a document set of 500,000 pages or so. with a list of mysql urls to spider and index, it can be setup and live, fast.

Re: FAQ hosting site (was Re: An Idea)
David, Sure; it's the least I can do. Look for mysql.justpickone.org to be in the DNS tables by tomorrow. By then the [EMAIL PROTECTED] mailing list will be ready for subscriptions, too. Fine. http://mysql.justpickone.org/ works :) Now, what do we need to do to be able to update this FAQ? I can't create ssh accounts for everyone, but we might arrange ftp Let's set up a PHP thing with MySQL. That's quite fast and easy to do. I could contribute some code. My suggestions (database design): 1. We need an authors table, and everyone who wants to be an author (contributor) can mail you, and you will set up accounts for these persons. The authors table will, of course, be used for database authentification / to update the admin pages. 2. For the actual content, we will need only one table, with question (varchar), answer (text), timestamp and a couple of id's that refer to other tables. 3. For the beginning, I would suggest we only have two more tables: category (installation, privilege system, ..., generally speaking, the main chapters of the manual) and difficulty (beginner, advanced, expert). _Not_ to be edited by the authors, to keep the FAQ smooth and simple. - We can make this more complex when necessity comes, with ratings, automated checks for double entries etc. My suggestions (frontend): 1. For end users, a very simple search. As Jim (JamesD) pointed out, Alkaline could do the job. Then again, Alkaline will search (and before, index) documents, and not databases. For the beginning, I would prefer just a simple input box for the search. 2. Output preferably as html files, i.e. nothing like index.php?cat=installationdifficulty=beginnersearchterm=windows, but rather something like /installation/beginner/windows/1.html. IMHO, this is easier to refer to in a mailing list, and easier to click. Maybe we can set up Alkaline on those html files, as an alternative search for the database search. 3. Authors should be instructed to first search via the end user interface before inserting a new entry. If they do want to insert something new, they should simply select category, difficulty, paste the question, type (or paste) the answer. 4. The author login should be extremely convenient, with a persistent cookie, so an author will not actually have to login more than once (from the same browser/machine). 5. An author should be able to insert new content and to update his / her own content, nothing else. - What I said about database design applies to the frontend, too.

RE: FAQ hosting site (was Re: An Idea)
I'm not following this threath.. but.. Use PHP to fetch mail from a mailbox, insert all questions into a database. Create a searchtool to search the database. No need to have way to many ppl as author. If you want you could have some ppl maintaining a list of keywords per question or remove a question from the database.. If you really persist to create something of your own you shouldn't create catagories. Most ppl don't really understand under which catagory their question could be found. Those who do will probably find an answer much quicker using google. --B. -Oorspronkelijk bericht- Van: Stefan Hinz, iConnect (Berlin) [mailto:[EMAIL PROTECTED]] Verzonden: woensdag 1 januari 2003 22:26 Aan: David T-G; mysql users Onderwerp: Re: FAQ hosting site (was Re: An Idea) David, Sure; it's the least I can do.

Hi Like the look of the way its taking shape. I am not sure if there is existing faq software (I've checked sourceforge and freshmeat without much luck) we could use, or if someone can do a better job :) but I have a content management system written, together with a lot of the search functionality needed for the faq. It can mix database stored content with static content, so it would probably do the job with a little work. It also does the membership authorisation/management.

For the beginning, I would suggest we only have two more tables: category (installation, privilege system, ..., generally speaking, the main chapters of the manual) and difficulty (beginner, advanced, expert). _Not_ to be edited by the authors, to keep the FAQ smooth and simple. - We can make this more complex when necessity comes, with ratings, automated checks for double entries etc. My suggestions (frontend): 1. For end users, a very simple search. As Jim (JamesD) pointed out, Alkaline could do the job. Then again, Alkaline will search (and before, index) documents, and not databases. For the beginning, I would prefer just a simple input box for the search. 2. Output preferably as html files, i.e. nothing like index.php?cat=installationdifficulty=beginnersearchterm=windows, but rather something like /installation/beginner/windows/1.html. IMHO, this is easier to refer to in a mailing list, and easier to click. Maybe we can set up Alkaline on those html files, as an alternative search for the database search. 3. Authors should be instructed to first search via the end user interface before inserting a new entry. If they do want to insert something new, they should simply select category, difficulty, paste the question, type (or paste) the answer. 4. The author login should be extremely convenient, with a persistent cookie, so an author will not actually have to login more than once (from the same browser/machine). 5. An author should be able to insert new content and to update his / her own content, nothing else. - What I said about database design applies to the frontend, too. We can make it more complex later on, when the need arises. We can have user contributed notes, fine grained search criteria, etc. In the beginning, I would suggest to follow the KISS principle (keep it simple stupid).

The 111 is the error code that MySQL generates. Check if your computer has a firewall, and make sure to enable port 3306 from external IPs e.g. on redhat using ipchains-based firewall, add: -A input -s 0/0 -d 0/0 3306 -p tcp -y -j ACCEPT to your /etc/sysconfig/ipchains file (or however the box is configured for the firewall). You'll also want to replace -s 0/0 with something a little more restrictive. cheers.. Dan On Thu, 2 Jan 2003, Peter Lovatt wrote: Hi Is '111' the IP it is trying to connect on?

Hello, I had a problem few days ago. I'm doing my questbook, and I were thinking what would hapen if I delete some row. Now I know, nothing. I had one column ID (auto_increment) in my table. I wanted it to be one by one even after deleting, so I changed it by myself. But then (after deleting the last ID was 17, and before 32), next ID was 33, not 18. Is there any function, which can change it? If not, mayby you'll try to do something like that. It's right, I can do it by myself not using auto_increment, and giving the ID number MAX(ID)+1, but if there is such function it would be realy fine.

What you describe was the behaviour in older MySQL versions and it has been changed because primary keys should never be reused. Never. If you need it to have no holes, you are abusing the primary key for something which it is not intended for (visible entry numbering?). So, yes, you have to either implement it yourself, or, what I would recommend, have a seperate column for it or calculate it in your application, whatever makes most sense for your use.

If not, mayby you'll try to do something like that. It's right, I can do it by myself not using auto_increment, and giving the ID number MAX(ID)+1, but if there is such function it would be realy fine. Sure, you can do it, but you should lock table, retrieve max id value, insert max+1 value, unlock table. -- For technical support contracts, goto https://order.mysql.com/?ref=ensita This email is sponsored by Ensita.net http://www.ensita.net/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Egor Egorov / /|_/ / // /\ \/ /_/ / /__ [EMAIL PROTECTED] /_/ /_/\_, /___/\___\_\___/ MySQL AB / Ensita.net ___/ www.mysql.com - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

RE: An Idea
Hi My first thought was that the docs on mysql.com should do the job, but, although they answer most technical questions, often more down to earth stuff like 'How do I store images' or 'how do I get started with SQL' isn't there, or it is difficult to find. The other problem is that the documentation is often technical to point that it is difficult to understand, even as a reasonably competent database programmer. I think newbies (and not so newbies) could feel totally overwhelmed by much of it. So (taking a deep breath !) I would be prepared to lay the foundations for a faq / knowledge base aimed specifically at this type of questions and to manage it. So, any thoughts? Where do we go from here?

Hi Michael, Using two select's we already solved the problem. The challenge is to make the same thing using just one select. I need to know if is there an way to get the last date or the 10th index to make the WHERE part. Like the LAST_INDEX() function, that gets the last AUTO_INCREMENT...but I just saw apllacation using the update command. Well, any new ideas? Best Regards, Felipe -Mensagem original- De: Michael T.

RES: RES: SQL Select Idea
Hi Michael,
Well, the SQL Query you requested is exatcly the one I'm asking! :-)
Like I said in other message, I solved the problem using TWO queries. In
the first one I get the 10th date. In the second one I use this date to
LIMIT the result to what I want. But is not a question of solving the
problem, but a question for a better designed query. I just want to use 1
(one) select to do the same thing that the two selects above do, if it is
possible of course. Below, I will show you the actual scenary, and after,
the question, how can I optimize it to use just one select?. If I can get
the value of the LAST index, I can subtract 10 indexes from this value and
get only this range of values, doing this I will get the last ten dates
without the LIMIT 0,10 that don't give me what I want.
Actual scenary:
// This is the main select that give me the last ten dates.
$sql = select pa.codigo,arquivo,label,tipo,DATE_FORMAT(data,'%d/%m/%Y -
%H:%i') as ndata,RS,ref_wicie from processo_arquivos as pa,cliente as
c,processo as p where pa.codigocliente=c.codigo and
pa.codigoprocesso=p.codigo ;
// This is the FIRST select that catch the LIMIT date
$sql2 = select data from processo_arquivos as pa,cliente as c,processo as
p where pa.codigocliente=c.codigo and pa.codigoprocesso=p.codigo order by
data desc limit 0,11;
$conexao-Query($sql2,$this-banco,$this-valor);
$i = 0;
if ($conexao-Select($this-banco)){
while (($this-valor =
mysql_fetch_array($this-banco)) ($i10)){
$i++;
}
$dataLimite = $this-valor['data'];
$sql .= and data'.$dataLimite.' ; --- Here I
select the last
ten dates.
}
What I wanted:
--- ???
Just do what I'm doing above using only ONE select.
Any tips?
Best Regards,
Felipe

RE: Data base driven web page idea - need help!
Here's my QUESTION! Because some of the program information is large I don't want to query the data base everytime do I? Define large? Are we talking mixed media types (PDF/Word/PowerPoint) or plain text/HTML? As someone has already suggested, you might be better to save the files on the disk and store the filenames in the database instead. Then again, you said some of the information is large. What's the ratio? If it's small enough, fitting it in the DB might not be so bad. Depends on the hardware. Since you're pulling static pages from disk, not SQL, it would probably scale better. Always looking for a challenge, I would look at the kind of data you're dealing with. If it's of similar format, you may be able to create a SQL strucutre that would allow more flexibility with your data. Render the data in different views where applicable or at least enforce a theme on your system. Of couse, XML/XSLT is more suitable for that and I've gone way overboard... This would take up to many resources. So I've decided to write a program ... every night and remove the old ones through a cron job? If you're eager to store it all in the database, I would do so. It doesn't sound like this stuff is going to change often. Throw a reverse-proxy squid in front of apache. Even running on the same machine will help a LOT. Avoid cronjobs and nightly generated static files. That practice does NOT scale and can be very difficult to manage. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Profile it first. You may find MySQL handles the load just fine on the hardware you're using and you don't need any such fancy tricks. You may also find that simply adding Expires: headers to your output on the cacheable pages means that you get fewer queries (and have the same effect as static pages). FWIW, I use ETag's as well which I make an MD5 hash of the latest TIMESTAMP in the tables being queried. This allows the browser to check if the ETag has changed for a page when requesting it, have the server do a very simple query to find out if it should rebuild the page or not, and let the browser use the cached page if not. -- Michael T.

Re: Data base driven web page idea - need help!
Hi Grant: The answer to your question depends on a lot of details. In most cases, the solution you have chosen is just fine. The real question you need to answer is, Does your solution meet your needs? If you can answer yes to this question, your solution is fine. Your solution gives you a couple of advantages: 1. As you said, fewer hits against the database. 2. Faster downloads for your user. Static HTML pages download faster than a dynamic alternative. 3. Static pages will get crawled and added to search engines; sometimes dynamic pages won't. Some disadvantages: 1. You have a delayed update to your Web page. If a faculty member notices a critical error on a Web page, they must contact you or otherwise figure out how to trigger an update. 2. There are things you can do with a dynamic page that you cannot do with a static page. Here's my QUESTION! Because some of the program information is large I don't want to query the data base everytime do I? Like I said, your solution will probably work just fine, but it is probably unnecessary. You say the program information is large, but it would have to really REALLY large for it to make much difference. With a college of 1600 students, it does not sound like your Web site is going to have much traffic. Php and MySQL are pretty efficient. My advice is to test your assumptions; does retrieving the large Web pages from the database make much difference?

Is this standard practice, if not what would be a better way of doing this. This college has about 1600 students? There are always several possible solutions and which one is the right for you depends on many factors you have not told us. Regardless which solution you choose in the end, try to get usage numbers from the current college program pages (hits/day) and build a test database and a minimal prototype regarding your solution and see if it is able to scale to the usage numbers you got. Do not forget to take into account special times of days (max usage is often 3 times higher than average) and special times of year (I presume there are times in school year, when the college program is accessed much more often). That said, some let's consider some possibilities: 1. As you said, one solution is to simply make dynamic PHP pages. You presume that this will be too slow, but be sure that this is indeed the case (PHP+MySQL are quite capable), because this is the solution that makes the least work. In short: least work, scales worst, always up to date. 2. As you also said, you could create static pages at night. That is the other extreme (the following points are somewhere in between). Regarding the fact that the college program probably will not change often, this sounds like a reasonable approach, should be fast enough for sure, but also means quite a bit more work, as it is not easy to get it correct all time. Most work, scales best, up to 24 hours out of date. 3. A variant of 2: Build the static pages when a database entry changes (i.e. on push). Whether this is feasible and how many work it makes depends on how many pages are affected by a change. It scales a little bit worse than 2., but should be still good enough by far and has the advantage that the pages are always up to date. If only one or two pages are affected by a change it is more reasonable than 2. for sure. Creating the static pages the first time needs some handiwork. Much work (depends on changed pages), scales almost best, always up to date. 4. This is a hybrid: Create cached pages/parts, but save them in the database (or disk, if you like more) and display them via PHP (there is a PHP to support for that, IIRC). You can see that as a variant of 1., just with the additional benefit of some caching. Cache pages would be created on request, if the page is not cached yet or outdated meanwhile (on pull). This solution fits best if the data changes often (where 2. would be a big no-no), but scales bad on restart. Medium work, scales good, always up to date. 5. Another hybrid: Do not create the cache pages yourself. Simply build the back-end as in solution 1. and put a caching proxy (e.g. squid) before it. The main drawback in comparison with. Depending on proxy, may scale bad on restart. Depending on configuration and usage may even be faster than 2. Is as out of date as you configure it to be: the more current the pages shall be, the worse it scales (because it less often hits the cache). Medium work, scales good, actuality: as configured. 6. As 1., but allow client-side caching of pages. This only has positive effects on reloads or often visited pages. Least work, scales bad, actuality: as configured (same as 5.) Since 1. allows to continue with 6., 5. and 4., I suggest to start with solution 1. and then continue as much as need arises.

As someone who uses 5 6 together quite often (as suggested), I can tell you it works very well (and very responsively). Your point about oft-used pages is interesting, but it only applies in a special circumstance that, in my experience, doesn't happen often (although Slashdot does consider this): If a page would require significant database resources and the source information changes more rarely than the data is accessed and/or the data may be accessed when it is inconvenient to load the database server with such a query, generating the page offline and storing it makes sense (like the Slashdot archived stories). In most cases, however, doing no caching at all is sufficient and allowing client-side caching takes the load off the frequently used pages (which is all you really care about usually) and adding Squid or Apache doing caching in front of your live server takes away hits to the same data from multiple requestors. Since 1. allows to continue with 6., 5. and 4., I suggest to start with solution 1. and then continue as much as need arises. I agree with this, personally. -- Michael T. Babcock CTO, FibreSpeed Ltd.

I need help. I am building a database for a small college that wants to be able to update their program information for each department through an web/gui program. I've decided to use, MYSQL, Apache, PHP and FreeBSD as the OS. (I built my web page this way) Here's my QUESTION! Because some of the program information is large I don't want to query the data base everytime do I? I've got a web site which takes just this approach, but there are pros and cons with it. The upside, is that if most of the information is fixed, then you're swapping database accesses and the overhead of a CGI script for a simple 'GET' request. It clearly works best when the rate of change for the raw data is relatively low, because it implies that you generate the page(s) once but server them up many times. The downside is the delay between entering new data and it being available on the site. In some applications this may be critical. The method that I used is to record a timestamp every time the database is updated, to have a script running permanently in the background looking at this timestamp. If it's greater than zero and more than 5 minutes old, the pages get regenerated and the timestamp is then set to zero again. The reason that I chose this approach is that updates are relatively rare (a dozen or so times a week), but the hit rate on the site is orders of magnitude higher. Also, it gave scalability at lower cost than tuning CGI scripts and the Apache server environment. The underlying point though, is that you need to look at the pattern of both accesses to the site and updates to the database and decide based on that. The site I'm talking about is here : www.pubfun.com if you feel a need to look round.

Fw: A new Idea for FULLTEXT searchs
mysql, query speed up, sql _ Sorry I may be bothering you but I was thinking (gosh! this is so bizarre on me) that may be we can make MySQL SGML compatible. I agree that MYSQL cannot be manipulated to handle jerarquical information because this is not the object and isnt mine either. May be we can add a NEW FEATURE ON INDEXING AND FULLTEXT that consists on avoiding the indexing of tags (as groups of words embrassed by and ), and support to add new rules to this one. In this case, we may use direct HTML code (for example) without worries of indexing the tags, and allow the developer to add new functionality as RTF support and TEX. Am I int the good way or I'll need to sleep more? Leonardo Javier Belén.

A new Idea for FULLTEXT searchs
mysql, query speed up _ Sorry I may be bothering you but I was thinking (gosh! this is so bizarre on me) that may be we can make MySQL SGML compatible.

Storing images in MySQL bad idea, performance-wise?
I'm working on a simple content management system that uses PHP and MySQL for updating a web site's text (stored in a MySQL database). (The PHP scripts that do the updating (my stuf) live on one web server, the actual DB data to be updated (my client's stuff) live on another.) So far, I've only had to he able to update the text content of a site--therefore, I've only had to bother to store textual data in the client's DB. But now the client wants to be able to upload/change/delete certain pictures on their web site--using my CMS tool--so I am faced with the following problem: Do I store all such images in the DB? (Which I understand reduces performance.) Or do I--somehow--store the images as files on the client's web server? And if so, how? (Because my PHP scripts are being executed on a different server.) ...Rene --- René Fournier, [EMAIL PROTECTED] Toll-free +1.888.886.2754 Tel +1.403.291.3601 Fax +1.403.250.5228 www.smartslitters.com SmartSlitters International #33, 1339 - 40th Ave NE Calgary AB T2E 8N6 Canada - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Storing images in MySQL bad idea, performance-wise?
Rene: I think a good deal depends on the size of the image files themselves. There are a number of apps that store small files (i.e.: icons, small gif's, etc.), which seems to make sense. Larger files may be problematic. There was quite a discussion on this issue here just last week ... do a search of the list archive for 'blob versus file' and read some informed opinions.
