[Zope-dev] How to insert time use mysql connection!

[TMGB]

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.
