Explicit Cursor


--====================================================
--Explicit Cursor
/*
An explicit cursor is a session cursor that you           construct and manage.
You must declare and define an explicit cursor, giving it a name and associating it with a query (typically, the query returns multiple rows).

we can process  Explicit cursor  data by using two ways as below

1. Open the explicit cursor (with the OPEN statement), fetch rows from the result set (with the FETCH statement), and close the explicit cursor (with the CLOSE statement).
2. Use the explicit cursor in a cursor FOR LOOP statement
