Opening a Cursor
Opening the cursor executes the query & identifies the result set that consists of all rows that meet the query search criteria. For the cursors declared using the FOR UPDATE clause, the OPEN statement also locks these rows. An illustration of the OPEN statement is as shown:
DECLARE
CURSOR c1 IS SELECT ename, job FROM emp WHERE sal < 3000;
...
BEGIN
OPEN c1;
END;
The Rows in the result set are not retrieved when the OPEN statement is executed. Instead, the FETCH statement retrieves the rows.
