Re: create a table inside a function

A very simple and incomplete example:

CREATE OR REPLACE FUNCTION new_table(int) returns bool AS
$$
BEGIN
       IF $1 = 1 THEN
               EXECUTE 'CREATE TABLE x()';
       ELSIF $1 = 2 THEN
               EXECUTE 'CREATE TABLE y()';
       ELSE
               EXECUTE 'CREATE TABLE z()';
       END IF;

       RETURN TRUE;
END;
$$
language plpgsql;

SELECT new_table(1);



Use EXECUTE and be sure you can't be the next victim of SQL injection. If you need some userinput in the EXECUTE-statement, use quote_literal() and/or quote_ident().
