Cursor For Loop

We can use Cursor for loop when we want to fetch & precess every record  in a cursor.Cursor for loop will terminate when  all of the records in the cursor have been fetched.

Syntax:-
For record_index in cursor_name
loop
{Statements...}
End loop;


Record Index is is the name of record.

Cursor Name is the name of cursor that you wish to fetch records from it.Statements are the

statements of code to execute through the cursor for loop.

Here is an example of Cursor for loop.


DECLARE
  CURSOR EMPCUR IS SELECT * FROM EMPLOYEES;
BEGIN
  FOR EMPREC IN EMPCUR LOOP
     DBMS_OUTPUT.PUT_LINE(EMPREC.LAST_NAME||' Earning '||EMPREC.SALARY);
  END LOOP;
END;
/
In this example we have created a cursor Empcur & the Cursor will terminate after all records

have been fetched.
