Try with a complicated where clause where your where_clause is a page long ...

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
