[Zope] Getting Auto Increment value
I am working with zope mysql. I have a table with SERIAL column type, I create z-sql method for insert operation, how can I get the value for the auto increment column? I know that in mysql I can call last_insert_id(), how do I call it, should I create another z sql method and if I do, how can I be sure the the value return is for my insert command and not for another. Is there a way to call 2 query from the same z sql method? I am really lost on this, any help will be wellcom.

You should be able to write two ZSQL methods and wrap them into a PythonScript. So you call the PythonScript instead of the ZSQL method(s) directly. In addition there is a sql-delimiter tag in DTML afaik - possibly undocumented. I would go for the PythonScript + 2 ZSQL methods approach. -aj begin:vcard fn:Andreas Jung n:Jung;Andreas org:ZOPYX Ltd. Co.

Re: [Zope] Getting Auto Increment value
I am suspecting that serial in MySQL works like serial in PostgreSQL in which a sequence is automatically created. If so, you should be able to query the last_value field in the sequence without having to call the function. The field name might be different in MySQL, I don't know. This will give you the last value inserted and if you need the next just add 1. Also, if it is an auto increment column and again if it is like PostgreSQL then all you have to do is use the word 'default' without quotes and it auto increments the value for the new insert. See if there is a default for your serial field. Thomas On Thursday 11 June 2009 08:36:21 Merav Ben-David wrote: I am working with zope mysql.
