Re: [despammed] Destination table by variable?

** 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.
