Обсуждение: Is there a GoTo ?
In this function I have to GOTO to a label1, but GOTO keyword is not working, can you please help me in getting the way from which I am able to jump from a particular code to label.
Thanks...
CREATE OR REPLACE FUNCTION test(i integer) RETURNS integer AS $$
BEGIN
IF i<0 THEN
RETURN i + 1;
ELSE GOTO label1;
END IF
<<label1>>
RETURN null;
END;
$$ LANGUAGE plpgsql;Hi

no, plpgsql has not GOTO statement. It cannot be implemented in interpret type used by plpgsql.

Hi İlyas
As noted by other there is no GOTO
you can move the goto code into the else statement
or move that code into a new function call and return that function
or just return null in the else if that is all the it is doing
CREATE OR REPLACE FUNCTION test(i integer) RETURNS integer AS $$
BEGIN
IF i<0 THEN
RETURN i + 1;
ELSE return second_test( i );
END IF
RETURN null;
END;
$$ LANGUAGE plpgsql;
CREATE OR REPLACE FUNCTION second_test(i integer) RETURNS integer AS $$
BEGIN
return abs(i);
END;
$$ LANGUAGE plpgsql; I know TSQL and PL/SQL have this but look at all the gotchas when constructing code with GOTO's
