Re: how to speed up a simple query? can anyone help with an ideea?
Creating a combined index can help MySQL in using this index for both the where condition and the order by clause. Try the query with an index on cat,date and with date,cat; maybe one will be faster than the other. This partially solved my problem. Thanks a lot. However I am facing a new problem here. The query where I am ordering by a column is much more slowly than the same query NOT using SQL_CALC_FOUND_ROWS select SQL_CALC_FOUND_ROWS * from table by date desc - this query takes about 1.2 s select * from table by date desc - this query takes about 0.1 s Using explain I have noticed that the first query is using filesort and I cannot figure out why exactly... I could use count() to figure out the total number of results for the navigation and this would be defintelly much faster since now as I have tested but I was thinking if anyone else had this problem before and if you have found any work around... After some checkings In have discovered that this is more or less a bug http://bugs.mysql.com/bug.php?id=1274 But after checking very ddpe here and trying all possibilities I think this is a little different... Let me know if anyone wants to see the table structure...

Re: SELECT duplicate rows
Well, doing on all tables at once woule probably bring the server to its knees due to the cartesian product producing a VERY large temporary table. You can do it on two tables at once like this (if my memory serves): SELECT * from mytable as t1, mytable as t2 WHERE t1.column1 = t2.column1 AND t1.column2 = t2.column2 AND t1.column3 = t2.column3 AND t1.id t2.id Of course, you can extend that to as many tables as you want, but the syntax and performance complications quickly arise. I would recommend comparing all your tables to one another, two at a time. A quick perl or C script should accomplish this quickly. For 10 tables, that is only 45 queries. Not bad. j- k- On Wednesday 21 April 2004 12:56 am, John Mistler said something like: Thanks for the response, Joshua. I am so very new to MySQL, that I am afraid I require more guidance.

Re: Randomly selecting from table
If you want to guarantee that the selections are different, rand() doesn't quite do it, as you will get a repeated value with the appropriate probability. You will need to keep a record of what values have already been seen. Then, use something like select ... from my_table left join my_records_used using (my_id) where my_records_used.my_id is null order by rand() limit 1 Date: Tue, 20 Apr 2004 13:08:01 -0700 (PDT) Subject: Re: Randomly selecting from table From: Daniel Clark [EMAIL PROTECTED] To: Eve Atley [EMAIL PROTECTED] Guess you could use the rand() function and look for a matching row id!?!

Re: Multi-user / transactions question..
Jeremy Smith said: A typical auction lasts around 90 minutes, and consists of a whole lot of furious refreshing of the auction board by the participants since each player only has a 2 minute clock. You might wish to look into using a different mechanism for this so you can push the latest bids to the user instead of depending on their refresh. Java applets can do this, and Flash Shared Objects make this very easy. They have the obvious drawbacks (accessibility, plugins, etc.), but when used properly they can significantly reduce the server load and bandwidth consumption. Since there is so much clicking going on, and my php code and mysql calls (including the transactions that decide which new player should be nominated to the board) obviously happen with each user click, is there any way to hide the guts of the work so that when they click refresh all they are doing is viewing the state of the respective tables at that time. Have transactions update summary tables (HEAP?) and query those summary tables. In other words, I don't need 4 people simultaneously calling the functions that decide which player should be nominated next, awarded the player that was won to the necessary roster, deducting money, etc. With four people calling the function at once, I am forced to lock up the rows and rollback 3 of the transactions. Is there any way to have them all call the same function that only gets executed once? There are ways, but they are generally implemented in the middelware, not the database. The best you can do in the database is use the summary tables to detect and abort conflicting transactions as early as possible.

RE: Multi-user / transactions question..
I appreciate the reply, I do plan on expanding this to make the use of flash and a flash server at some point, but I want to offer the option of HTML auctions as well. I will look into summary tables as it is not something I am familiar with. Btw, I'm not sure why you sent me a link on How To Ask Questions The Smart Way. That seemed rather insulting, especially without explaining what you thought was so problematic about the way I framed my question. Jeremy -Original Message- From: Jochem van Dieten [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 21, 2004 5:35 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: Multi-user / transactions question.. Jeremy Smith said: A typical auction lasts around 90 minutes, and consists of a whole lot of furious refreshing of the auction board by the participants since each player only has a 2 minute clock. You might wish to look into using a different mechanism for this so you can push the latest bids to the user instead of depending on their refresh. Java applets can do this, and Flash Shared Objects make this very easy. They have the obvious drawbacks (accessibility, plugins, etc.), but when used properly they can significantly reduce the server load and bandwidth consumption. Since there is so much clicking going on, and my php code and mysql calls (including the transactions that decide which new player should be nominated to the board) obviously happen with each user click, is there any way to hide the guts of the work so that when they click refresh all they are doing is viewing the state of the respective tables at that time. Have transactions update summary tables (HEAP?) and query those summary tables. In other words, I don't need 4 people simultaneously calling the functions that decide which player should be nominated next, awarded the player that was won to the necessary roster, deducting money, etc. With four people calling the function at once, I am forced to lock up the rows and rollback 3 of the transactions. Is there any way to have them all call the same function that only gets executed once? There are ways, but they are generally implemented in the middelware, not the database. The best you can do in the database is use the summary tables to detect and abort conflicting transactions as early as possible.

However, the user and system times displayed will not include the amount of cpu time used by the db server. Do it a few times and vary the number of inserts to build an accurate picture. Alternatively, you may be able to do this easier in version 4.1, where you can use %f in time_format to get milliseconds, so hopefully now() retrieves milliseconds too(?): select time_format(now(), '%H:%i:%s.%f'); to get timestamps to the nearest millisecond.

Renaming a column
Hi, I am hoping to get some advice on a problem I have. I have a table that have 109 million records and is about 30 G in size. I need to rename a column, because it seem that localtime have become a reserved word. The alter table statement makes mysql generate a tmp table and regenerate the index. And with a 30G data file and a 20G index file this takes some time. I have tried the following: 1. first I did a ALTER TABLE xxx CHANGE.. 2. next I copied the #sql-zxzxxcxcssd.frm file 3. then I killed the ALTER TABLE command 4. In the end I stopped mysqld and switched the old .frm file with the new (from 2.) And it seem to work. My question is if any body now / can think of any reason not to change the column name this way. Waiting for the index to rebuild takes at least a week, and I don't want to wait. I have only changed the column name, not the type. And the column is not part of any index. Hope to hear from you!

Can someone suggest a good resouce that explains the contents of Innodb show status in detail. The page on www.mysql.com gives a very cursory overview of the output. Buffer pool size, free buffers, database pages, and modified database pages are in 16k pages. The buffer pool hit rate simply says the fraction of page reads satisfied from the innodb buffer cache, in this case 1000/1000 == 100%. Unfortunately, I'm not really aware of a better reference.

Replication problem
Hi, i'm new to this list, but i use mysql for years an are very happy with it. However, today i ran into a problem that i couldn't find a solution for: I set up database replication with a master and one slave, and it works fine so far. I rewrote my application (web based written in php) so that it executes all queries that insert, delete or update rows are executed on the master, and all other queries on the slave. Fine. But what, if the master fails? I want users to be able to continue working on the slave, and this works fine for webpages that just do select statements. I thought that, in case of the master being down, i could execute all data-modifying queries on the slave, and also store these queries in a special table or file, and re-execute them later on the master if the master becomes available again. The problem is, that i then may get Duplicate entry ... for key ... errors on the slave, if a record was already inserted into a table with unique keys, and that the sql-thread on the slave then exits. Is it possible to make the slave ignore such errors (i found no option for this in the docs) and just stupidly continue replication, or does anyone have a better idea how to set up such a scenario?

Re: Modelling specialized M:N relationships?
I'm actually i deep doubts with this. Price is not a thing itself, good point. But in my case, it was the best way i found out to model. Suppose you got a company the rents a place (just a big room, or a party house) for any kinda envents you'd to make. The company is clear an entity, and the price would probably be its attribut, despite the following problem: This company charges diferent prices depending on the kind of party you'd like to make on its party House. You might have a company that charges you the following. - Wedding party U$100 - Under Graduation party (prom) U$200 - high school grad party (hs prom) U$ 300 Beyond that, there are the ordinary companies that have only one basic price for any kind of party (they don't change their prices depending on the parties). That's why i decided to model it as an entity, but i'm not sure in two aspects. - Should i have a M:N or a 1:N relation between these entities (note that this is actually not that trivial, maybe modelled both ways) - Should i just have a column in my price entity to specify the kinda party (like PARTY_TYPE) or just have 3 or more specific columns for the party type (lik PRICE_WEDDING, PRICE_GRADUATION, PRICE_HIGH_SCHOOL).

Query question
I'm trying to select specified data from a field in a table.
The field from which the data has to come contains the following:
'something;else;anything;everything;name;my' (and so on), it's a long text.
I need in the case just 'my' from the field, thus between the ';'. This
time there are only two characters, but I can't say by forehand how many
letters there will be.
The only thing that's sure it comes after 'name', so I have the
following query:
SELECT SYS_IDX, LEFT(RIGHT(C,
LENGTH(C)-LOCATE(';',C,LOCATE('name',C))),10) FROM A;
This return's up to ten characters after the name, somethimes this is to
much, sometimes to many. Does anybody knows how to go from here.

That page was handled differently than my others. That page used JSTL queries to get it's result set. My other pages did it from a Java bean. Using Java I could query and retrieve all the date from that table but the JSTL queries gave that error. But apparently it's a bug in the driver so I have been wary of those drivers. Did you ever look and see what encoding your JSPs are set at? If it's not UTF-8, you will see this behavior, because JSTL will use the encodings of your JSPs. It is strange (but not dismisable) that it would work from stock java bean and not a JSTL tag and that this would be caused by a _driver_ bug. I can try the nightly snapshots but this is bad because this project will need to be production ready and if it needs to use trial stuff like this... MySQL-4.1 is an ALPHA. The JDBC driver is an ALPHA, and you are using features that are only in the ALPHA. For this reason you are going to have to put up with using nightly snapshots and/or doing your own builds if you want the latest bug fixes. I'm gonna try all this week to get this working but I can't really afford to spend more time than that. My client got busy so I got some breathing room. I already know that using SQLServer and their JDBC driver works just fine. But the whole purpose of the project was to convert everything to a lower cost alternative. The app has already been converted from ColdFusion to JSP and I also wanted to go from SQLServer to MySQL since most of the hosting I've seen offer MySQL with the most basic service and SQLServer only with their higher more expensive plans. I understand your frustation, however your comparison to SQL Server's JDBC driver which is GA to an ALPHA version of MySQL and its state of issues is not an apples-to-apples comparison. As far as I know, the issues you are having with our software are all fixed, and are available in nightly snapshots, but not a release.

RE: Gripe with MySQL
Peter J Milanese said: The lack of error checking on the server side means better performance in my opinion. Does it? Or does client side error checking use server resources as well? Lets suppose that we want to validate a new message that is entered into a thread on a messageboard. Then we need to check that the thread we want to insert the message into actually exists. If we want to do that client side we need to open a transaction, query the threads table, insert the new message and commit. If we check it server side we just create a foreign key to the threads table, insert the message and if it gives a foreign key error we handle the exception. Which one would put a bigger load on the server? Naturally running an expensive regex on the input to make sure the message does not contain any cross site scripting code is something you would do on the client, but validating *relations* is something you should do in your *relational* database. I would have to agree that error checking does belong on the client side (at least from my experience), and it can be a lot more productive as a database, and not a workflow tool. As an application developer, I don't trust the employees to be able to enter data correctly. That is why I validate the input they send me. As a DBA, I don't trust application developers to be able to validate relations correctly. That is why I validate the input they send me.

BLOB data and mysql_escape_string
I'm attempting to put an image into a BLOB field. I'm using Visual Basic 6 with ADO, although I wouldn't think that's making a difference. I create a string that contains the binary representation of the file. At this point the string is 5064 characters long. I call mysql_escape_string and the string becomes 5350 characters long. That seems normal as there will be a lot of characters in the binary data that need to be escaped. After selecting it out of the database, the size of the data retrieved is 5023 bytes. Clearly this is a problem when trying to re-create the file. Any suggestions as to why? Is there a function other than mysql_escape_string that should be used with binary data? Do I have to write my own? If so, what bytes need to be escaped? I assumed just NULL, ', \ and ...but didn't bother writing one since mysql_escape_string seemed to do what I wanted.

Re: Searching the Docs

RE: Confused by max and group by
Well, in traditional SQL you'd use a sub-query for this type of operation. In MySQL 4.1+ you could do this: SELECT t1.myindex, t1.myval, t1.mycat FROM mytest t1 WHERE myindex = (SELECT max(t2.myindex) FROM mytest t2 WHERE t2.mycat=t1.mycat); once again, just illustrating the theory, it may not work as is. SQL is really *meant* to have sub-queries, so the temp table solution is just a work around until sub-queries make it into the production version of MySQL.

? while ($speaker = mysql_fetch_object($qid_speaker)) { ?
option value=? pv($speaker-first_name)
? ? pv($speaker-last_name) ?
? pv($speaker-first_name) ? ?
pv($speaker-last_name) ?
? } ?
/select
$qid_speaker = db_query(SELECT first_name, last_name FROM people WHERE
speaker = 'Y' ORDER BY last_name);
I am using this in a form select drop down box.
What I need to do is reuse this results set in another drop down box. but I
can not figure out how to do this.
If I use the mysql_free-result($qid_speaker) and then try to do the query
again I get a mysql_fetch_object(): 12 is not a valid MYSQL result resource.
TIA

You've now posted this four times today. Was that on purpose? I can only assume so, as
some people have absolutely no sense of netiquette whatsoever.
Why, you ask, has no one replied with the infinite wisdom to solve your problem? I,
for one, haven't because your original email is at least vaguely unintelligible. Have
I asked for more information so that I might be more helpful? No, I've been busy.
Posting over and over and over again, though, seems to have worked, so readers, take
note -- if at first you don't succeed, try, try again until you annoy someone into
listening.
*sigh*
That said, sir, could you possibly provide more details for your situation? Your code
is a bit jumbled. We have no idea what pv() does, for instance. Nor db_query(). These
are not standard PHP functions, so you'll have to forgive us if we're all a bit
clueless and unwilling to help.

Re: re-using a results set
Thank you Chris for that answer. I did not know if it was a mysql problem
or php problem.
Again I apologize (especially to Mike Johsnon) for the multiple request. I
was getting a return error on the list and I thought it was a configuration
error on my part. I did not mean to upset anyone. Thank you again for the
answer and I will try to have better netiquette in the future.

MySQL 4.0 and Unicode
Ok, what is the recommended way of handling Unicode data with version 4.0. I believe I read that it doesn't support utf8 so how do people with version 4.0 deal with it? Do they store is as a binary object perhaps? Looking for techniques and ideas so I'll be able to see how much work is involved working with 4.0. Also foreign keys. Do the innob tables of 4.0 support foreign keys? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Stormblade (Shaolin Code Warrior) Software Developer (15+ Years Programming exp.)

Re: reuse a results set
I generally set an array if I'm going to reuse a result. In your example, I
would do something like the following:
? $i=0 ?
? while ($speaker = db_fetch_object($qid_speaker)) {
$speakerName[i]=sprintf(%s
%s,$speaker-first_name, $speaker-last_name);
i++;
?
option value=? pv($speaker-first_name)
? ? pv($speaker-last_name) ?
? pv($speaker-first_name) ? ?
pv($speaker-last_name) ?
? } ?
/select
Then the next time I wanted a drop box with the same result set:
? $j=0;
while ($j$i)
{
printf(option value='%s'
%s,$speakerName[j], $speakerName[j]);
}
?
I hope this helps...

Converting tables to innoDB
Hello Mysqlers, I have a few small DB's (less than 10,000 entries per table) that track computer inventory in a mid-sized organization. Currently, all of the tables are MyISAM. Is there any compelling reason to convert these to InnoDB? We're not having any performance or size issues... everything works great right now. I'm just hearing how InnoDB is the only way to go today, any tips on whether or not to switch?

Syntax problems in MySQL v. 4.1.1-alpha-standard-log
Apologies if this is an easy one, I'm stumped! I'm having some trouble with syntax running MySQL from the command line. I'm running MySQL 4.1.1-alpha from the OS X standard installer package on a G5 running panther. I have logged into MySQL as the root user, providing the correct password, and I wish to see a list of the databases I have available, so I enter the following command: mysql show databases; I get back the following: ERROR: No Query Specified If I try again, adding a 'Like' clause, things clear up: mysql show databases like '%'; ++ | Database (%) | ++ | cme_admin | | cme_course_administration | | cme_course_finances| | cme_course_info| | cme_faculty_info | | cme_public | | cme_user_data | | mysql | | test_course_administration | | test_course_finances | | test_course_info | | test_faculty_info | ++ This same type of problem is cropping up in a number of different settings. For example, I can use the test_course_info database: mysql use test_course_info; Database changed But trying to show the tables in this database suffers from another syntax problem: mysql show tables from test_course_info; ERROR 12 (HY000): Can't read dir of './test_course_/' (Errcode: 2) It seems that the full name of my database is not being read for some reason. So I try just to show tables, after all, I am using the proper database, right? mysql show tables; ERROR: No query specified So what if I try the same as before, and use wildcards? mysql show tables like 'tbl%'; +---+ | Tables_in_test_course_info (tbl%) | +---+ | tblcoursecomments | | tblcoursedaterepeatexceptions | | tblcoursedaterepeats | | tblcoursedates| | tblcoursedatesubgroups| | tblcoursefaculty | | tblcourselocations| | tblcourses| | tblcoursesponsors | | tblcoursetypes| | tbldaterepeatperiod1s | | tbldaterepeatperiod2s | | tbldays | | tblensessions | | tbllocations | | tblregfromaccess | | tblsponsors | +---+ 17 rows in set (0.00 sec) Similar problems are showing up with things as simple as a select query: mysql select * from tblcourses; ERROR 1096 (HY000): No tables used BUT I JUST LOOKED There is in fact a table called tblcourses in the databases. What am I doing wrong here? So, lets try to see the columns in this table: mysql show columns from tblCourses; ERROR: No query specified mysql show columns from tblCourses like '%'; **Big list of columns deleted to save space** One of the colums is called course_id (it's the primary key, in fact). Lets try to select that column: mysql select course_id from tblCourses; ERROR 1054 (42S22): Unknown column 'course_' in 'field list' Once again, we seem to be missing everything after the final underscore in the column name. I'm stumped as to why these queries are not working. Does anyone have suggestions for me?

Re: Problems adding table to Crystal Reports using ODBC Connection
The only other thing I can think of off the top of my head is Crystal's very poor handling of prefix and postfix data in sub-reports.

We have recently added a table to our database that needs to be added in addition to already existing tables on some of the reports. I Add the table, update the SQL Query and insert the field on the report. When I try to preview the report I get the following error message: ODBC error: [MySql][ODBC 3.51 Driver][mysqld-4.0.16-nt]Unknown table 'tablename' in field list.

Anyone know what's going on here? I'm trying to move towards the TTX concept but that will take me a couple of weeks. In the mean time, I have to get this problem resolved!
