Subject: full usefullness of CURRENT OF ???
Could anyone give us an idea as to the full usefullness
of CURRENT OF? Here are my two separate examples:
/* 1 this one has a CURRENT OF */
DECLARE
CURSOR EmpCursor IS
SELECT *
FROM Emp
FOR UPDATE;
BEGIN
FOR EmpRec IN EmpCursor LOOP
UPDATE EMP
SET SALARY = SALARY * 1.08
WHERE CURRENT OF EmpCursor
END LOOP;
END;
/* 2 same as above, except without the CURRENT OF */
DECLARE
CURSOR EmpCursor IS
SELECT *
FROM Emp
FOR UPDATE;
BEGIN
FOR EmpRec IN EmpCursor LOOP
UPDATE EMP
SET SALARY = SALARY * 1.08
WHERE EMP_ID = EmpRec.Emp_ID;
END LOOP;
END;
/
Is one more efficient than the other? If I could have done
business without the CURRENT OF, then why did oracle made
it available?
thx
maa
