[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.

 Normally I'm against big things, 
 I think the world is going to be saved by millions of small things. 
Too many things can go wrong when they get big.
