Problems with replication
Description: Hi! My name is Ales Perme. A college of mine Samo Login gave me this adress, which was given to him by Monty, to report MySQL bugs to. The first bug report today from me is connected with replication. Our production comprizes of Windows and Linux machines. MySQL verson we are using on production is 3.23.36-log and on our development setting 3.23.49-nt-log. On both of these versions we experiance the same bug. We experiance replication problems in the following configurations: 1. Windows NT 4 (master) - Windows NT 4 (slave) 2. Windows NT 4 (master) - Linux (slave) Linux to Linux and Linux to Windows works okay. The problem is as follows: Suppose we have a database called Trident3-P-0, with exactly that case! We replicate that database to the secondary with another name, with replication parameter replicate-rewrite-db. This is a part of my.cnf file with these settings on the slave machine: replicate-rewrite-db=Trident3-P-0-Trident3-S-0 replicate-rewrite-db=Trident3-P-1-Trident3-S-1 replicate-rewrite-db=Trident3-P-2-Trident3-S-2 I usualy connect to MySQL server running Windows NT 4.0 with mysql -h master.hostname.domain -u user -ppassword and with a USE statement change the active database to Trident3-P-0. Whatever I do on that databese on master now DOES NOT replicate to slave. I trided to use all kinds of cases when changing the database on master - no change of replication behaviour! Fix: Now, I found out that if instead of using USE I use \r command then the replication magicaly starts to work. So if I type \r Trident3-P-0 instead of USE Trident3-P-0 then the replication to Trident3-S-0 on the slave machine starts to work. Replication also works if I connect to the database at the time of establishing connection with the server. So if I connect to the master server using mysql -h master.hostname.domain -u user -p password Trident3-P-0 then replication also works. The problem applyes to configurations when we replicate from windows master to windows slave or windows master to linux slave. Obviously there is a problem with the windows version of mysql.

Performance of ORDER BY on an indexed column
I'm a little bit confused about what EXPLAIN is saying about a query I'm doing with an ORDER BY clause. I've read and re-read the parts of the manual about how ORDER BY is optimized, but it won't sink in to my thick skull for some reason. I've got an index on a column called price, which is an INT: mysql show columns from homes like 'price' \G *** 1. row *** Field: price Type: int(11) Null: YES Key: MUL Default: NULL Extra: 1 row in set (0.00 sec) which I frequently sort by. EXPLAIN says that a filesort is necessary to do this: mysql explain select * from homes order by price \G *** 1. row *** table: homes type: ALL possible_keys: NULL key: NULL key_len: NULL ref: NULL rows: 3628 Extra: Using filesort 1 row in set (0.00 sec) even when I do an ALTER TABLE homes ORDER BY price. Why is a filesort required to sort these rows? Is this something I should worry about as this system goes from 1500 queries/day to 15000 queries/day to 15 queries/day? Is there something I can do that is faster? Sorry if this is a stupid question; this is the first database I've designed where I've had to put much thought into performance.

Joining Multiple Listings
Greetings, I'm having a real problem with this one, so I hoped I could seek some guidance from the guru's inhabiting the mailing list, and then hopefully in the future I can offer some assistance myself... (Skip down four paragraphs if in a hurry!) My wife, who always wanted her own bookshop, decided to try selling online instead, right now through the services of half.com - so far she's doing well. However, she's making enough sales where it'll soon be time to have her own site instead. To accomplish this, I figured it would be easier, rather than scanning the UPC in from each book and starting from scratch again, to grab information from half.com's current list, then we expand ourselves from there. We also have the services of a wonderful program called ReaderWare, available at www.readerware.com - I don't normally plug peoples' products, believe me, but this has been invaluable. Regardless, I've ended up with two tables - one containing the information I got from half.com (ISBN, UPC, price, condition, name, author), and one from Readerware (ISBN, name, author, subject, etc). Now joining those two tables together to end up with the perfect listing - which would contain the ReaderWare complete details coupled with the half.com price and condition - wouldn't be too difficult at all. I'm having trouble because both tables contain multiple listings of some books (with different prices and conditions), with the only field related between them being the ISBN, the other fields are not guaranteed to match every time. So, before I bore you all to death, rather than write a long complicated PHP script to figure this all out, I figured that MySQL would have no problem joining these two tables together and producing the perfect output table for my needs. It's 3:30am, and my contacts are blurring up on me I'm stumped! Unfortunately, joins aren't my strongest point. I've tried a variety of different SELECT statements, and usually end up with multiple listings as they are supposed to be, but all with the same price, for example. Help! I would include a few of my failed SQL statements, but I don't want to get laughed at. :) To conclude... two tables (books and half), both contain an ISBN field (books_isbn and half_isbn), the first table will comprise the name (books_name), author (books_author), and description (books_description), the second table will comprise the price (half_price) and condition (half_condition), and the books table will contain multiple entries with the exact same information - apart from the id number, of course, while the half table contains multiple entries with the same ISBN, but different conditions and prices. Sorry for the long version, but I figured a detailed explanation would probably help. missysbooks.com may get there someday! Thanks for your time, and I'd appreciate a CC to my own email address ([EMAIL PROTECTED]) as well as to the mailing list.

Re: MySQL Power ?
From: Richard Spangenberg [EMAIL PROTECTED] Can mySQL handle... ...as well as Oracle. MySQL is different than the big databases like Oracle, Informix, etc. MySQL is comparatively small and fast, also cheap. As such, it doesn't come with all of the bells and whistles that others might. You may not need built-in tools like clustering when you see the relative cost. For instance, if you have to pay $50,000 to get an Oracle solution to a problem, or could use MySQL and spend $10,000 on in-house programming for that solution, which is better? --- Rodney Broom - 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: MySQL Power ?
I'm currently running MySQL for a big, fast app without problems. BUT: I'm in the middle of specifying a new application with a high load, and I'm consideing looking for alternatives to MySQL because without InnoDB, it gets really slow on tables with frequent updates and reads (no row locking). We have, for example, a session table that records all the incoming requests for holding state. Since it's constantly being updated and read, it is frequently locked, and there are often instances where 50 reads will stack up while a lock is held. This slows down the whole database. With InnoDB, I'm sure this problem goes away, but as soon as we go to InnoDB, we have to pay for backups and support, which means we start looking around at 'pay' solutions. Is there something I'm missing?

Command Line Tool
I'm having a bit of a problem trying to get MySQL version 4.0.1-alpha-max-nt binary version to accept The Command - Line Tool to run a script to create a table. My operating system is Windows 2000 Professional. I can connect with MyODBC-3.51.02.exe without any problem and run successful queries. I am using the model example from chapter 4.8.2 The Command-line Tool. I am trying to create a table in the test database example in MySQL I am logged in correctly and using the test database that is created when MySQL is installed as best as I can tell by reviewing the command line mysql status. I am issuing the command line statement at the mysql prompt: mysql test create.sql; I get the following mysql error: ERROR 1064 You have an error in your SQL near 'mysql test create1.sql' at line 1 Basically, I have a script named create1.sql with the following syntax: CREATE TABLE Names ( NameID int(11) NOT NULL auto_increment, FirstName varchar(30) NOT NULL default '', LastName varchar(30) NOT NULL default '', PRIMARY KEY (NameID), KEY idx_Names_LastFirst (LastName,FirstName) ) TYPE=MyISAM; INSERT INTO Names VALUES (1,'Morton','Salter'); INSERT INTO Names VALUES (2,'Jimi','Filmore'); INSERT INTO Names VALUES (3,'Eustace','Shoe'); INSERT INTO Names VALUES (4,'Archy','Roche'); INSERT INTO Names VALUES (5,'Catherine','LaGrande'); Anyone got any suggestions?

RE: Problems with UPDATE in v3.23.49 (is this a bug)
According to the manual, the DATETIME field can be stored As a string with no delimiters in either 'MMDDHHMMSS' or 'YYMMDDHHMMSS' format, provided that the string makes sense as a date. So this should provide you with the format you require. TIMESTAMP was created so that we would NOT have to make an extra call to NOW() when doing INSERTs Finally, you replied directly to me, instead of the list, but I'll forward to list here...

[O/T] problem with the list and Eudora/attachments
I've been having an off-list discussion with gordon52 at slingshot dot co dot nz, who is having a problem posting anything to the list. Apparently when he sends something, the list manager thinks it's got attachments and bounces it. Now when he sends me a message - no attachments. Can anyone out there in MySQL-land help, since I'm using Lotus Notes, and not Eudora? At this 16:45 5/04/02 +0200 told us all something interesting :- Your message cannot be postsed to mysql@ because it contained an attachment.

authentication problem
Hey guys, We're having a weird authentication problem. We have a .jsp (on box1) that tries to connect to a MySQL database (on box2). The privileges have been set to give insert, update, delete to the user. GRANT select, insert, update on d_name.* to d_user IDENTIFIED by d_user; It works fine one day and then the next morning it doesn't work. To hack around, we changed the .jsp to use the root user login (only in our development environment to find the error) and it worked, only to have it broken again the next morning! The only thing that runs overnight is a mysqldump script, which calls this command: mysqldump -u$USERNAME -p$PASSWORD --all-databases It seems like the privileges get messed up by mysqldump? We've also been doing a flush privileges after any change to the grant tables (db, user, host). to isolate the problem, we've removed all related d_user entries. The way it looks now is that the db table is empty, the host table has an entry so that box1 has access to the databases on box2, and user has an entry for root coming from localhost, box1, box2, and to be safe, '%'. does mysql get confused when there's an '%', and then also other entries in the host column of the user table for the same user? Any help would be great...it's been really frustrating. thanks, Don - 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?

It isn't valid SQL. You are, I think, trying to do an update rather than an

no, you need to follow the list rules when posting. That's why you see a
lot of posts that have a line at the end that just says

or something similar.
And to answer your question, it appears that you are actually attempting
an UPDATE, not an INSERT? i.e.
UPDATE Sellers
SET Logo = 'images/helilogo.jpg'
WHERE seller_id = 1

At my previous job, we had to do this with MS SQL Server 2000 because the built-in triggers and foreign keys and the like were simply too slow so we did it programatically instead.

That statement is wrong because INSERT INTO statement inserts a new record
to the table so you can't have a where restriction. If you wanna change the
logo value where seller_ID=1 then use UPDATE TABLE syntax. See:

Perhaps because it's not MySQL, but PHP related...
Original #2 message :-
1) PROBLEM :-
Ive sent this message several times, from my 'Eudora' Email programme to
the
group a message was received advising my message was rejected because i
had
an ATTACHMENT.
i'm NOT using/sending any attachments...
Perhaps you try to send the mail in HTML format instead of PLAIN TEXT ?
EG :-
echo(pShowing all the tables within database :
B.$database./B/p);
However, both these commands :- show the same thing...
echo(pShowing all the tables within database :
B$database/B/p);
echo(pShowing all the tables within database :
B.$database./B/p);
Are there any reasons / Rules in which you can put a variable name within
the
double-quotes, instead of closing the quotes putting the variable
after/before a full-stop.
Just curious - No worries.
G.
A small example :
You have a variable $database and you want to print $database followed by
some letters ('forumtest' for exemple)...
In this case you have to use echo blabla.$database.forumtest;

RE: MySQL Power ?

I'm currently running MySQL for a big, fast app without problems. BUT: I'm in the middle of specifying a new application with a high load, and I'm consideing looking for alternatives to MySQL because without InnoDB, it gets really slow on tables with frequent updates and reads (no row locking). We have, for example, a session table that records all the incoming requests for holding state. Since it's constantly being updated and read, it is frequently locked, and there are often instances where 50 reads will stack up while a lock is held. This slows down the whole database. With InnoDB, I'm sure this problem goes away, but as soon as we go to InnoDB, we have to pay for backups and support, which means we start looking around at 'pay' solutions. Is there something I'm missing? Steve However, my impression is that while the answer, for the very highest volumes, is that Oracle is better, the point at which Oracle betters MySQL is *much* higher than doubters might think. So, if anybody give the reply that Oracle is best at the high end, please could they also try to quantify the point at which MySQL begins to run out of steam - and what it is it can't do and Oracle can at that point. (For example, MySQL can handle high read loads by use of replication, but would bottleneck on high write loads - I think). - 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?

Updated file - Speed ?
6:35 a.m. (writing this on the web)MYSQL :-) Hi - in my first PHP file, :- - earlier this week, Ive posted a few messages about my PHP webpage which Roger Baklund was able to help me start off.. Anyway, - Ive been to some MySql Help sites found some useful commands, which ive been able to use sucessfully... Ive uploaded a text version of my latest PHP script :- http://homepages.slingshot.co.nz/~gordon52/4.txt (view source, to view the PHP code).. Basically, it finds out what databases youve got on your system, you select one of your choice. it then lists all the tables for that database. Ive now expanded it, to show you all the field names/columns included in the table view the values of each table/row/column. The code for this last bit, is near the top of the script.. $action =='tables' Question :- 1) when i go to the 'user' tabvle in the mysql database.. it says there are 4 (FOUR) rows of information. It sucessfully lists the 1st row - Names of each column.. - Then it proceeds to loop through all (4) rows of data, Listing each row.. However, This last bit (looping) is REALLY slow, compared to the first part. my screen says there are 4 rows of data, But it only displays 1 row, then stops.. Does anyone know a) Why it doesnt loop through all 4 lines of my database ? b) Why it is a LOT slower, doing the 2nd loop. (a loop within a loop) PS, I realise other people see what i'm trying to do.. have made / or aquired better scripts than this.. but ive only been dealing with PHP/Mysql for a week or so this is my 1st big script. PPS - I'm more concverned at getting it going - rather than looks..

Cross-database joins
Can you please tell me, is it possible to do queries that join MySql tables that are in different databases? I have a couple of Delphi database programs that use Paradox tables. I'd like to move them over to something else that is faster. These programs are set up so that they have a shared database on our server, and then a local database on each machine. I have queries that have to be able to join tables in the local and the server db's. I tried this with Interbase, and it doesn't support cross-database joins. I'm wondering if MySql can do this? If so, how would you modify the below query to show the different databases? Specifically, how would you specify the database that the table is in? SELECT D.BkID, D.Chap, D.Vrs, D.RTypID FROM :OntData:ScrpUF.DB D INNER JOIN :OntLclData:LclSrchBkParam.DB d1 ON (d1.BkID = D.BkID) WHERE D.ScrpUF LIKE %search text% *** If this is not possible, can this be accomplished with a UNION by selecting all the records in the local table, and joining the result set with the shared table? If so, how? Any help will be *greatly, greatly* appreciated.

Re: - Error 127
Hi, actually I know about current problem in 3.23.49a on linux at least - there's something weird with the cache I think. I've posted some reports with my ideas to the bugs list already. For you: I can get rid of such problems whenever they appear by doing : mysqladmin flush-tables They disappear after some time period possibly because the contents of the cache were flushed as the cache got full or whatever force pushed the data out from cache or whatever condition forced mysqld to reread status of teh table from disk again. Maybe this problem also shows only if the database on which you operate is accessible via some softlink from your datadir - i.e. if you can access your problematic table under two different databasenames. I might not be right, but this is our case at least. Further, when this error show up, do in this order: cd /usr/local/mysql/var/$dbname ls -la $table.* myisamchk -f -d -v $table.MYI mysqladmin flush-tables ls -la $table.* myisamchk -f -d -v $table.MYI mysql $dbname -e 'select count(*) from $table;' mysql $dbname -e 'check table $table;' mysql $dbname -e 'check table $table;' mysql $dbname -e 'check table $table;' I think the SELECT will already work. Compare if the output if both myisamchk commands were same. I guess if you omit the `mysqladmin flush-tables` command, the SELECT or maybe even first CHECK TABLE will fail, but then the next commands wil work fine. This is still not confirmed by the developers, but I know they have now quite a hard time to get through my mails. ;) Hope this helps Martin - 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?

Group commit in innodb?
Hi, Does InnoDB use some form of group commit like BerkeleyDB and Postgresql? In Postgresql you can specify a COMMIT_DELAY to force a wait before the commit returns. Disk IO to the log files can be reduced quite alot if you tweak this setting, and it can be very useful when tuning batch-like systems where the clients that issues the commits can wait for a period of time. -- Magnus - 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?

Tricky Query...
here's the scoop: Basically I'm listing pieces of information from a two-key table and I am not getting the information I want. BACKGROUND Consider this sample table (which although goofy, does illustrate what I'm attempting to do) SELECT clientid, revision, name, address FROM clients; +--+--++---+ | clientid | revision | name | address | +--+--++---+ |1 |0 | Fred Flintstone| 55 Bedrock Way| - Fred |2 |0 | Barney Rubble | 57 Bedrock Way| - Barney |3 |0 | Pebbles Flintstone | 55 Bedrock Way| - Pebbles lives with Fred |4 |0 | Bam Bam Rubble | 57 Bedrock Way| - Bam Bam lives with Barney |1 |1 | Fred Flintstone| 145 Stonewall Terrace | - Fred Moves |3 |1 | Pebbles Flintstone | 145 Stonewall Terrace | - Pebbles Moves with him |4 |1 | Bam Bam Rubble | 25 Mammoth Road | - Bam-Bam Moves out |3 |2 | Pebbles Rubble | 25 Mammoth Road | - Pebbles changes name; moves in with BamBam +--+--++---+ By using the clientid and revision keys, you can create a 'snapshot' of client data. For example, if you made an invoice out to Fred, when his address was 55 Bedrock Way, the invoices table, would record clientid and revision id.

You could do the SELECT max(revision), clientid FROM foobar GROUP BY clientid first, then programmatically either cycle through all of them doing mini-selects or glop together a giant or statement (probably that will fail when you have large numbers of clients). You could create a temporary table, use an INSERT ... SELECT statement to populate it with the above data, then join that table with your original table. You could programmatically maintain a 'most recent' flag which would be update whenever a new record was inserted. I'm going to set up a fake DB like yours and experiment with it. ... ...

Table crash!
The table has mysql select count(*) from repository; +--+ | count(*) | +--+ | 5673838 | +--+ records inside. 1. I get table a table crashed whenever I try to fix it or check it with MYISAMCHK using -r, -o or -f parameters. And the table is then no longer usable. Don't do this when the table is in the cache! The correct way (open two xterms and do commands in this order): mysql flush tables; mysql lock table repository write; $ myisamchk -f -d -v repository.MYI # this will tell you the status of the table based on the index file If the output says the table is broken, then myisamchk -r $table myisamchk -f -d -v $table mysql unlock tables; mysql flush tables; mysql check table $table; If it it looks fine (see the line Status), then mysql unlock tables; mysql flush tables; mysql check table $table; if the check table complains about bad number of rows present versus expect, like below: ++---+--+---+ + | Table | Op| Msg_type | Msg_text | ++---+--+---+ + | $db.$table | check | warning | Size of datafile is: 679740 Should be: 0| | $db.$table | check | error| Record-count is not ok; is 501 Should be: 0 | | $db.$table | check | warning | Found 501 partsShould be: 0 parts | | $db.$table | check | error| Corrupt | ++---+--+---+ + then do mysql flush tables; mysql lock table $table write; $ myisamchk -rq $table.MYI # fix the index while NOT modifying the .MYD file with data $ myisamchk -f -d -v $table # check the result mysql unlock tables; mysql flush tables; mysql check table $table; In any case, you should have working table. I believe this is your current problem. But you should upgrade to 3.23.49a at least as there're some bugfixes in previous versions. There're probably still some (I've reported some ;) ), so you should look for 3.23.51 to get more fixes. I've learned a lot from this thread: http://lists.mysql.com/cgi-ez/ezmlm-cgi?9:msn:11533:nkocbgofapjhfkjheipi To quote the summarized secret from that thread: - You must do FLUSH TABLES before you manipulate the .MYI or .MYD files outside of mysqld. - You can't just replace a .MYD file with another; You have to always use the .MYD and .MYI files together. (Actually, if you want to save backup space, you can go away from this restrictions by just copying the first 8K from the .MYI file; This should contain all the meta-information that myisamchk / REPAIR TABLE needs to reconstruct the rest of this file. Regards, Monty The only way to fix this is to generate a new empty .MYI file with the correct header information (Just run 'truncate table ..' on it) and then copy the old .MYD file over the empty one. Is this nice explanation of truncate table mentioned somewhere in the myisamchk section in manual? I was missing this very serious information - that I cannot re-create .MYI via myisamchk but have to use some `truncate table`, which really doesn't sound to be the command I need when repairing table. ;) [...] If you delete the .MYI table you have to generate it from the .frm file with 'truncate table'. Perfect explanation what to do in such case. I just missed this idea from you example -- me You can't just replace a compressed .MYD file with a not compressed. The .MYI and .MYD files must always be kept together. This is because all meta information (like the record type) is stored in the .MYI file. mmokrejs OK, I thought the index can be re-created safely from .MYD and .frm. mmokrejs With your explanation somewhere below that .MYI I can recreate with mmokrejs `truncate table` explains it well. And them myisamchk can fix the .MYI mmokrejs according the current status of .MYD. I thought that `truncate table` mmokrejs truncates the .MYD file, and this I didn't want to happen intentionally in mmokrejs these experiments. Yes. TRUNCATE TABLE does truncate the .MYD file. If you want to use this to generate an index the way I used it, you must first do a backup of the .MYD file and then copy it back after TRUNCATE TABLE. The only way to fix this is to generate a new empty .MYI file with the correct header information (Just run 'truncate table ..' on it)

Re: InnoDB is better than MyISAM ?
At 01:54 PM 4/5/2002, you wrote: I have seen many people saying that InnoDB is a great deal, that InnoDB rocks, etc. and I am concerced about how much better InnoDB is compared to MyISAM tables. Can someone tells me wich one is better ? I know that InnoDB have foreign keys support, but I deal very well without then since now. My interests are justified becaus eI got out of a very old struct ( DBM + Text Files ) and jumped head first into MySQL - MyISAM tables, but my site has a good deal of visitors ( about 30.000 unique visitors by day ) and speed and reliability are my primary concerns. I plan to use replication in MySQL, and I would like to know if InnoDB is better than MyISAM for this. Have you ever heard the old saying, If it ain't broke, don't fix it?.bg If your website is mainly for read access to your database then you're not going to need InnoDb. InnoDb is great for multi-user updates because of its row locking. If you have more than say 30-50 users at a time updating records in the *same* table, then yes row locking will help. You will need to analyze the log file to determine how many processes are waiting for table locks on your MyISAM tables to determine if the switch to InnoDb is warranted. InnoDb inserts (for a single user) are much slower (for me it is around 10x slower) than MyISAM because InnoDb does a lot more work. This may dismay a few users initially, but then they realize InnoDb will maintain its speed much better than MySQL when there are a lot of heavy updates. So if your database is mostly readonly, then stick to MyISAM tables. I don't know if InnoDb supports replication or not. You'll have to check with Heikki. Brent _ Do You Yahoo!?

FYI (general consumption), both Sybase and MySQL sent people to the test floor, IBM provided email support, Oracle and Microsoft declined to be involved. I would say that the lower TCO of MySQL compared to Oracle would be a deciding factor in many cases (given a relatively equivalent feature set). Don't get me wrong; I'm certainly not an Oracle schill. I harbor a deep and ancestral hatred for Oracle's database server software, especially from an admin standpoint. I was simply highlighting the fact that in plain technical terms, MySQL was right there with Oracle, and far and above the other offerings. Anything on top of that (the TCO issues you raise, for example) are above and beyond that. I have to admit that I have not yet tried the .NET/OLEDB interfaces to MySQL, and honestly, am not willing to until the SP support in MySQL is fully functional. I will say that all of the VS/ADO/.NET development I am doing for IIS/MSSQL is being done with an emphasis on easily migrating to MySQL in the future (for example, making sure that I don't use any Microsoft-specific constructs on the database side). Why am I still working with MS technologies? Because they work together well (as the article also stated), and at this time I am more interested in shorter development time (which VS.NET provides in spades) than in purity of ideology. VS.NET/IIS/.NET Framework/MSQQL 2K works fine for me for now, but as soon as I can plug in MySQL on the back end without missing a beat I'm there. - 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?

Are you trying to create a new table with an existing table's structure only ? or with the structure and data? If you just wanna duplicate a table with the data inside it you can use CREATE TABLE .. SELECT ... syntax. More info is at: http://www.mysql.com/doc/C/R/CREATE_TABLE.html IF you just wanna copy the structure, do a SHOW CREATE TABLE on the existing table and copy and paste its CREATE TABLE syntax to create the new one with a different name.

Difference between Unique Index and Primary Key?
Here are a few easy philosophical questions for a change: 1) For performance or storage benefits, is there a difference between a Unique Index and Primary Key? 2) Is there a reason why I should use Primary Key instead of a Unique Index? 3) Why isn't there a syntax for create primary index index_name on table_name (fieldlist) ? I know a primary key can be added with Alter table, but if I'm defining indexes for a table, it would look a lot better in the script if I was using the same syntax.

Re: InnoDB is better than MyISAM ?
On Fri, 5 Apr 2002, BD wrote: At 01:54 PM 4/5/2002, you wrote: I have seen many people saying that InnoDB is a great deal, that InnoDB rocks, etc. and I am concerced about how much better InnoDB is compared to MyISAM tables. Can someone tells me wich one is better ? I know that InnoDB have foreign keys support, but I deal very well without then since now. My interests are justified becaus eI got out of a very old struct ( DBM + Text Files ) and jumped head first into MySQL - MyISAM tables, but my site has a good deal of visitors ( about 30.000 unique visitors by day ) and speed and reliability are my primary concerns. I plan to use replication in MySQL, and I would like to know if InnoDB is better than MyISAM for this. One note here is that transactions aren't preserved for replication with InnoDB, so you loose part of one of the major advantages of InnoDB. Rollbacks are O.K., since I don't think that goes out to the slaves until the commit, but if the master or slave goes down after part of a transaction is sent to the slave, you get a partially committed transaction on the slave. How critical this is depends on the application, and still is no worse than MyISAM which has no transactions to begin with. I think Heikki Tuuri has mentioned plans to get this fixed, though I think I remember that he said that the problem was in MySQL, not in the actual InnoDB code, which makes sense. Have you ever heard the old saying, If it ain't broke, don't fix it?.bg If your website is mainly for read access to your database then you're not going to need InnoDb. Agreed 100%, but it doesn't hurt too much (except for index sizes) on readonly databases, so on our production system, we standardized on InnoDB for all tables for consistency, though we will allow for exceptions for tables that need features that aren't in InnoDB yet, such as full text searching. InnoDb inserts (for a single user) are much slower (for me it is around 10x slower) than MyISAM because InnoDb does a lot more work. This was not my experience. Without batching the commits, InnoDB lost out to MyISAM on our initial testing by about 1.5x rather than 10x. However, when I committed every 100 or so inserts, InnoDB beat out MyISAM by a small (25%) margin. This was with a single user hitting the database, a perl program that read in a text file, split it into fields, and stuffed it into the database one record at a time (identical programs except for handling the commits()). Now, this wasn't normal database activity, pure inserts into a freshly created table, but the results were still quite impressive. Also, I'm dealing with single-user activity, so there may have been some differences there as well. - 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?

Abandoned Cart Query
I'm trying to write a query that will tell me how many abandoned carts there are in a cart table I have. each item in a cart is a record, so simply querying on records won't work. What I need to count is how many distinct customerId's there are. a sample from the table looks like: cartItemId customerId productId 1944244 2139 1945244 2234 1946244 8291 1947198 4435 1948198 3342 1949221 3324 1950221 4432 so in this example, the number of abandoned carts would be 3, because there are only three unique customerId's. Any help on what that query would look like is appreciated! Thanks, Rory P.S.

Re: Problems with UPDATE in v3.23.49 (is this a bug)
It's not illogical at all. You often want (sometimes need) that field to make sure a record has not changed when you go back to update the row. MS Access (and others) uses this so as not to overwrite changes made since the record was retrieved. You can't always rely on the client to set field=NOW(), and it makes for that much less coding. mysql, query j- k- On Friday 05 April 2002 07:53, Hihn Jason wrote: Yes I did, but it is very long, and it was very long ago. Could someone please explain to me why this was done? It seems more confusing to do this than to not do this. Why when you can just say SET field=NOW() in the update statement would anyone build this auto update of timestamps in? (the kicker is you HAVE to do it for all timestamps in a schema past the first) Additionally, what if I wanted the time stamp format (without formatting (spaces, colons, and dashes)) (which I do) A very illogical feature I must say...
