There is probably several ways to do autoincrement with Zope and or python methods but I use the built in feature of MySQL. It doesn't have to be the first field of the database but here is the syntax to add an autoincrement field to an existing MySQL database: ALTER table mytable ADD ID INT NOT NULL AUTO_INCREMENT; This adds a field called ID to a table named mytable in MySQL. Of course you can change ID to any text. In the example I sent you the NULL was the first parameter in the Zsql method because ID is the first field in my database. You can use the command above at the MySQL prompt or you should be able to do it from a Zsql method using the test option, I suggest only testing it once I suppose you will just get an error message if you try to recreate the same field again. I actually use this for the record number which allows me to bring up a unique record according to record number because data in some other fields might be replicated. I don't know if MySQL has record numbers built in, I don't think so. Thomas Victor.Zhai@ogilvy.com wrote:

Dear: What you said is just the requirment of my project, I want to one field is an auto increment integer when user use one form to add something into my database. Should I modify my database structure.Make Null the first fields of the database? is there any other method to do that? How to realize the auto increment integer? Please give me some advice. Thanks a lot! Victor zhai.
