Hi there,
Im having a go at writing my first set of triggers for postgres and Im
having trouble with an error message which the trigger produces when it
tries to compile/call the function Ive written in pgsql. The error message
is:
ERROR: syntax error at or near ";"
CONTEXT: compile of PL/pgSQL function "text_update" near line 31
I cant find the error! As far as I can see the syntax is fine from whats in
the manual. Can anyone see what the problem with the function below is:
CREATE FUNCTION text_update() RETURNS TRIGGER AS'
DECLARE
allText TEXT;
currentRecord RECORD;
BEGIN
IF TG_WHEN = BEFORE THENRAISE EXCEPTION ''Trigger function text_update should not be called before
INSERT/UPDATE/DELETE'';
END IF;
IF TG_LEVEL = STATEMENT THENRAISE EXCEPTION ''Trigger function text_update should be called as a row
level trigger'';
END IF;
IF TG_OP = DELETE THENDELETE FROM cks_messagetext WHERE cks_messagetext.id = OLD.id;RETURN OLD;
ELSIF TG_OP = UPDATE THENFOR currentRecord IN SELECT textdata FROM cks_part WHERE cks_part.type = 1
ANDcks_part.sourcemessageid = NEW.id LOOP allText := allText || '' '' || currentRecord.textdata;END LOOP;allText :=
allText|| '' '' || NEW.subject;UPDATE cks_messagetext SET cks_messagetext.textdata = allText WHERE
cks_messagetext.id = NEW.id;RETURN NEW;
ELSIF TG_OP = INSERT THENFOR currentRecord IN SELECT textdata FROM cks_part WHERE cks_part.type = 1
ANDcks_part.sourcemessageid = NEW.id LOOP allText := allText || '' '' || currentRecord.textdata;END LOOP;allText :=
allText|| '' '' || NEW.subject;INSERT INTO cks_messagetext (id, textdata) VALUES (NEW.id, allText);RETURN NEW;
ENDIF;
END;
'LANGUAGE plpgsql;
Thank you for any help in advance.
