Question

Did there have a statement like Oracle’s SQL%FOUND in PostgreSQL? While, I want to judge the value if the SQL statement update or not.

The code just like below in PostgreSQL:

INSERT INTO TABLE_NAME
SELECT A,B
FROM TABLE_NAME_2
WHERE A>2;
IF SQL%FOUND THEN   ---error in PostgreSQL
C = 1;
ELSE 
C = 0;
END IF;

Answer 1

Yes, PostgreSQL has FOUND statement. Details here.

Example:

SELECT * INTO myrec FROM emp WHERE empname = myname;
IF NOT FOUND THEN
    RAISE EXCEPTION 'employee % not found', myname;
END IF;
