postgresql 8.4 erreur trigger/storedproc: comment résoudre ce problème?

Question

Un INSERT sur une table déclenche un proc stocké où l'erreur suivante se produit.

ERROR: column "targetedfamily" is of type boolean but expression is of type character varying 
    Hint: You will need to rewrite or cast the expression. 
    Where: PL/pgSQL function "fn_family_audit" line 19 at SQL statement 

Et voici le errantes proc stocké (notez que ma tentative de résoudre le problème en faisant CAST (NEW.targetedfamily AS BOOLEAN) ne semble pas fonctionner)

CREATE OR REPLACE FUNCTION fn_family_audit() RETURNS TRIGGER AS $tr_family_audit$ 
    BEGIN 
     -- 
     -- Create a row in family_audit to reflect the operation performed on family, 
     -- make use of the special variable TG_OP to work out the operation. 
     -- 
     IF (TG_OP = 'DELETE') THEN 
      INSERT INTO public.family_audit values (
     DEFAULT, 'D', OLD.family_id, OLD.familyserialno, OLD.node_id, OLD.sourcetype, OLD.familyname, 
     OLD.familynamelocallang, OLD.hofname, OLD.hofnamelocallang, OLD.targetedfamily, OLD.homeless, 
     OLD.landless, OLD.dependentonlabour, OLD.womenprimaryearner, OLD.landlinenumber, OLD.username , now()); 
      RETURN OLD; 
     ELSIF (TG_OP = 'UPDATE') THEN 
      INSERT INTO public.family_audit values(
     DEFAULT, 'U',NEW.family_id, NEW.familyserialno, NEW.node_id, NEW.sourcetype, NEW.familyname, 
     NEW.familynamelocallang, NEW.hofname, NEW.hofnamelocallang, NEW.targetedfamily, NEW.homeless, 
     NEW.landless, NEW.dependentonlabour, NEW.womenprimaryearner, NEW.landlinenumber, NEW.username , now()); 
      RETURN NEW; 
     ELSIF (TG_OP = 'INSERT') THEN 
      INSERT INTO public.family_audit values(
     DEFAULT, 'I',NEW.family_id, NEW.familyserialno, NEW.node_id, NEW.sourcetype, NEW.familyname, 
     NEW.familynamelocallang, NEW.hofname, NEW.hofnamelocallang, CAST(NEW.targetedfamily AS BOOLEAN), NEW.homeless, 
     NEW.landless, NEW.dependentonlabour, NEW.womenprimaryearner, NEW.landlinenumber, NEW.username , now()); 
      RETURN NEW; 
     END IF; 
     RETURN NULL; -- result is ignored since this is an AFTER trigger 
    END; 
$tr_family_audit$ LANGUAGE plpgsql;

Voici le déclencheur

CREATE TRIGGER tr_family_audit 
AFTER INSERT OR UPDATE OR DELETE ON public.family 
    FOR EACH ROW EXECUTE PROCEDURE fn_family_audit(); 

Je vous serais reconnaissant des conseils.

Answer 1

Votre problème est ici:

NEW.hofnamelocallang 

Votre insert a une colonne supplémentaire (apparemment NEW.node_id). Essayez de changer votre insert à:

INSERT INTO public.family_audit values(
     DEFAULT, 'I',NEW.family_id, NEW.familyserialno, 
     NEW.sourcetype, NEW.familyname, 
     NEW.familynamelocallang, NEW.hofname, NEW.hofnamelocallang, 
     NEW.targetedfamily, NEW.homeless, 
     NEW.landless, NEW.dependentonlabour, NEW.womenprimaryearner, 
     NEW.landlinenumber, NEW.username , now() 
); 

L'erreur que vous obtenez est essentiellement en train de dire que vous essayez d'insérer NEW.hofnamelocallang dans targetedfamily colonne (qui est booléen, pas varchar) en raison de la colonne supplémentaire que vous mettiez dans l'insert phrase.

Je vous conseille de toujours énumérer les colonnes dans lesquelles vous insérez des valeurs lorsque vous effectuez une insertion. Quelque chose comme ceci:

insert into table foo 
(col1, col2, col3) -- column enumeration here 
values 
(1, 2, 3);
