Hi,
I'd like to get 1 or 0 from a select on a boolean field.
How could I do ?
I tried the following rule, which I can't insert :
CREATE FUNCTION bool_to_int( boolean ) RETURNS integer AS ' DECLARE my_bool ALIAS FOR $1 ;
BEGIN -- Retourne 1 si true, 0 si false IF my_bool IS FALSE THEN
RETURN0 ; ELSIF my_bool IS TRUE THEN RETURN 1 ; ELSE RETURN
-1; END IF ; END ;
' LANGUAGE 'plpgsql';
CREATE RULE boolean_return AS ON SELECT TO DOCUMENT DO INSTEAD SELECT document_id, workflow_id,
type_document_id, image_id, theme_id, document_version, document_surtitre,
document_titre, document_chapeau, document_synthese, document_corps, document_pdf,
document_date_creation, document_mot_clef, (bool_to_int(document_online)) as document_online,
bool_to_int(document_valid)as document_valid FROM document;
psql:cnambo_proc_stock.sql:69: ERROR: select rule's target entry 15has different type from attribute document_online
Who could help me ?
