Re: functions

Thanks, Josh.

I really do not understand the philosophy involved.
Usually the client needs very often this kind of sets.
So, the only way for a client to get them is to issue
hand-made query strings
(e.g. pg_query(cnn, 'SELECT * FROM ...'), in PHP)?
Where are the advantages of pre-compiled code,
execution plans, etc? Probably it will take me some
time to accommodate.

And by the way, MSSQL has also functions. I think they
satisfy your requirements :)

Thanks.

Postgres 7.2.1, involving CURSORS. In 7.3, which will
be out in beta sometime soon, it will be possible to
have T-SQL-like row-returning Functions.There is one
other difference btw. Postgres Functions and MSSQL
Procedures; Postgres functions may be called within a
query, and MSSQL procdedures may not. On the other
hand, MSSQL procedures may return multiple result
sets, and I don't think anyone is proposing this for
Postgres.-- -Josh BerkusAglio Database SolutionsSan
