Thread: FW: Function

Is there nothing like SET NOCOUNT ON; in plpgsql
Is there any option like SET ANSI_NULLS ON in plpgsql.
Do we append # before the temp table names in plpgsql, like we do for
MSSQL ? In case no how do we create a temp table in a function in plsql?

For functions that return setof or complex types, you can do it as
select * from Proc_ConferenceSummary(...) as alias;

For simple functions you can just use:
select functionname(...);

What is this supposed to do for you?

The thing to remember with plpgsql is that it's compiled (unlike say plTcl). 
This means that it translates table-names etc. into oids. So what you have to 
be careful of is referring to a temporary table that is created, destroyed an 
re-created (because it's oid will change).

The solution is to use the EXECUTE command to build a dynamic query. Check the 
archives for plenty of other people doing this.
