Home -> Community -> Mailing Lists -> Oracle-L -> 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
