Обсуждение: Return dynamic columns of a temporary table

Hi, i am new to postresql and have been trying to convert some of our mssql procedures into postresql functions. What i have been trying to do is to somehow return a temporary table with dynamic columns. Is it possible?

it is possible, but usually it is not, what you want

CREATE OR REPLACE FUNCTION foo()
RETURNS SETOF RECORD AS $$
SELECT * FROM temptab;
$$ LANGUAGE sql;

but you have to specify columns in query

SELECT * FROM foo() (a int, b int, c int);

A style of PostgreSQL stored procedures is significantly different
than MSSQL - it is more close to Oracle.
