Re: little off-topic: stored procedures

Hi!

One reason to use stored procedures:
Reduces the number of the required interactions between the DB and the client. It may result better response time for the clients, and still lower load on the server.
Did you ever try to port your more difficult system to MySQL? :)
I did, postgres did with 1 sql statement, what MySQL did with 7-8. The throughput was similar.

It was the SQL problem, each vendor implemented differently, so stored procedures are the less portable things I have ever seen. If the java stored procedures will be implemented, we will be able to emulate the stored procedure systems of comercial databases easyly.

Is this the thing called "spagetti-code"?
