** High Priority **
Thank you all for the replies...
However, I can't get the EXECUTE statement to work... I think it has something to do with the quotation marks, any
suggestions?
CREATE OR REPLACE FUNCTION insert_object(_category_id int4, _header "varchar", _description "varchar") RETURNS int4 AS
DECLARE
destTable text;
insertString text;
id int4;
BEGIN
SELECT INTO destTable "category".table FROM category WHERE id = _category_id;
insertString := ''INSERT INTO '' || destTable || '' (category_id, header, description, created_on) VALUES (''
|| _category_id || '',''
|| _header || '',''
|| _description || '',''
|| DEFAULT || '');'';
EXECUTE insertString;
id := currval('object_id_seq');
RETURN id;
END;

Yes, you can build your SQL as string and then execute this with
EXECUTE.
