OK, what about using an External Method importing MySQLdb then?

select last_insert_id() as ID

works for me.

statement so far which I couldn't comfortably code in a Z SQL method.

Hm, I'd see it the other way round (Cursor coding in Python more 
complicated than using Z SQL/DA), but if you think so...

You can get the Connection String from the connection_string attribute 
of your ZMySQL instance.

Sorry, I forgot. I'm pampered from the german DZUG list which sets a 
"Reply to" automatically on every mailing... *big hint for the list
