2010/1/5 Andy Colson <andy@xxxxxxxxxxxxxx <mailto:andy@xxxxxxxxxxxxxx>> I have a function that's working for what I needed it to do, but now I need to call it for every id in a different table... and I'm not sure what the syntax should be. Here is an example: create or replace function test(uid integer, out vhrs integer, out phrs integer, out fhrs integer) returns setof record as $$ begin vhrs := uid + 1; phrs := uid + 2; fhrs := uid + 3; return next; end; $$ language 'plpgsql'; I currently use it once, I know the id, and just call: select * from test(42); all is well. But now I need to call it for every record in my employee table. I tried: select id, vhrs, phrs, fhrs from employee, test(id) I also tried an inner join, but neither work. Any hints how I might do this? # select id, test(id) from ids; id | test ----+--------- 1 | (2,3,4) 2 | (3,4,5) 3 | (4,5,6) (3 rows) is this what you want? if not, maybe # select id, (select vhrs from test(id)) as vhrs, (select phrs from test(id)) as phrs, (select fhrs from test(id)) as fhrs from ids; note: declare your function volatility - see http://www.postgresql.org/docs/8.4/static/xfunc-volatility.html note: in above example, a VIEW would be enough. -- Filip Rembiałkowski JID,mailto:filip.rembialkowski@xxxxxxxxx <mailto:filip.rembialkowski@xxxxxxxxx> http://filip.rembialkowski.net/
Ah, yes. That works. I don't like the array output so much, but the sub-select works.
