Raising error in postgreSQL

Question

CREATE OR REPLACE FUNCTION msgfailerror() RETURNS trigger AS 
\' BEGIN 
    IF NEW.noces< new.first_column THEN 
        RAISE EXCEPTION \'cannot have a negative sala         


        

Answer 1

there is nothing wrong with you the only thing is using quotes

please change :

RAISE EXCEPTION 'cannot have a negative salary';

to:

RAISE EXCEPTION ''cannot have a negative salary'';

'' is different from "

'' = two single quotes
