mysqlimport and \ as data
Hi Group, Does anybody have any expierence with mysqlimport and a comma separated file with data wich contains field data with a: \. For example I have the data in de column path: C:\temp. When I import this I got something like : c:||emp ... Does anybody know how to solve this problem? This \ occurs to much to do the job manually ;-) Thanks a lot.

Re: locking issues
Excuse me for late response. When I do it from the mysql prompt it works fine but trough the API (I use DAC for MySQL from microolap, maybe the bug is in there software!!) it doesn't work fine. I have try it on several versions: 4.1.1, 5.0.0 and 4.0.0. Thank you for your help.

Re: Query with IF acting wierd.
Amir, I don't know your table content but if you join two tables eg : table1(id, desc) and table2(id, refid, desc) wich containts: table1: 1 test1 2 test2 table2: 1 1 testbla 2 1 testbla and you select: select id from table1 where table1.id = table2.refid you got two rows (because if you show * it would be: 1 test1 1 1 testbla and 1 test1 2 1 testbla So distinct is the keyword for getting only the unique records.

I'm not saying this is the problem, but it might give you a direction where to look. Updating the table is done in code only.. its temporary data wich is collected in this tables before serieus update..\ Instead of trying a TmyTable, why not use a query component and create an UPDATE statement yourself to update the table. That would avoid all this. And have a look at the MyMonitor component to see what SQL get's executed when you're doing what you're trying to do.

Re: get rows not present using join _AND_ where clause
Okay, Now I understand what you want. (For people who try to unsub me from this list: Sorry I only try to help, if you are not intressted in it pleasee dont read) If you start using MySQL 4.1 (Only ALPHA) then you can use subqueries like this: select * from table1 where id not in ( select refid from table2 where thirdvalue = 'de') problem solved. But if you use an older version the only solution is to use a temporary table or make it in code. First you select al the values from table2 with thirdvalue 'de', walk trough this dataset while looking in table1 if theres a corresponding value. I think there are no other options. I have tried to rewrite the subquery to a left join, but i think it isn't possible, because he thirdvalue = 'de' makes a problem. It is no problem to get all rows from table1 who have no corresponding record in table2 with a left join: select table1.id from table1 left join table2 on table1.id = table2.refid where table2.refid IS NULL But you have the problem that there is a corresponding record in table2. I''ve tried to solve this with a union who returns a NULL value .

Somebody tried MySQL version 5 / Stored Procedures
Hi all, We want to migrate to MySQL, and because of its speed, we want to use MyISAM db. I plan to write code as an alternate transaction mechanism. But I have read that MySQL version 5 supports Stored Procedures (PL/SQL like). In PL/SQL it is possible to use in your stored procedures transactions (at the end (eg) of a stored procedure you can do a commit and in an exception handler (eg) you can do a rollback). My question to somebody who has tried version 5 (or the development team), is this possible in MySQL stored procedures too? So it is not nessecery for me to write much code, but just a little and in version 5 I write my transactions to stored procedures... In anticipation much thanks!!

Somebody tried MySQL version 5 / Stored Procedures
Hi all, We want to migrate to MySQL, and because of its speed, we want to use MyISAM db. I plan to write code as an alternate transaction mechanism. But I have read that MySQL version 5 supports Stored Procedures (PL/SQL like). In PL/SQL it is possible to use in your stored procedures transactions (at the end (eg) of a stored procedure you can do a commit and in an exception handler (eg) you can do a rollback). My question to somebody who has tried version 5 (or the development team), is this possible in MySQL stored procedures too? So it is not nessecery for me to write much code, but just a little and in version 5 I write my transactions to stored procedures... In anticipation much thanks!!
