Hi! I can't find any info about possible data types that can be returned from procedure. I want to return tuple. When I use OPAQUE as a return type I get error message that OPAQUE can be only returned from trigger. It is possible to do this without triggers? ------------------------------------------------------------------------ Code reviews are like sex, just anyone can do it, but skill and training can make you a lot better at it." - LJ Thomas
You _can_ return a tuple by doing this: create table foo(x int, y text); create function bar() returns foo as ' ... '; The only thing is, you can't do much with such a function (currently), you can only call it from a different function, and then break the result up: foo v=bar(); do_something(v.x); do_something(v.y); -alex On Tue, 5 Jun 2001, Andrzej Roszkowski wrote: > Hi! > I can't find any info about possible data types that can be returned from > procedure.

Currently you can't return tuples from "regular" PL/pgSQL functions. It heard this functionality will make it in 7.2. -Roberto -- +----| http://fslc.usu.edu USU Free Software & GNU/Linux Club |------+ Roberto Mello - Computer Science, USU - http://www.brasileiro.net http://www.sdl.usu.edu - Space Dynamics Lab, Developer Death to all fanatics!!!
