Обсуждение: Stored procedures

Good day,

I need help URGENTLY!!

I'm trying to compile a Stored Function that performs either an insert or an
update on a table. The function has 44 input parameters and returns an
integer. When compiling the function a get an error:

ERROR: functions cannot have more than 32 arguments

I would just like someone to confirm this. Can a function only have 32 input
parameters? If so, I'd have to use Prepared Statements then.

Thank you in advance.



Sincerely,

Yes, this is correct. You can increase the limit by recompiling, though
there a believed to be some performance issues associated with choosing
a limit higher than 32. search the mail archives for the specifics of
where you need to do this in the code.

The 32 arg limit is a compile time / reinitdb parameter.  I.e. you can
change it, but you'll have to first pg_dumpall your database, recompile
postgresql with a different limit, and then restore your database to get
more than 32 args.

But there are other ways around it, like passing a record type or array to
the function.
