⟩ How To Retrieve Data from an Explicit Cursor?

If you have a cursor opened ready to use, you can use the FETCH ... INTO statement to retrieve data from the cursor into variables. FETCH statement will:

► Retrieve all the fields from the row pointed by the current cursor pointer and assign them to variables listed in the INTO clause.

► Move the cursor pointer to the next row.

► Update cursor attributes like FOUND and NOTFOUND.

Here is a sample script showing you how to use FETCH statement:

CREATE OR REPLACE PROCEDURE ggl_CENTER AS

CURSOR t_list IS SELECT first_name, last_name

FROM employees;

f_name VARCHAR2(10);

l_name VARCHAR2(10);

BEGIN

OPEN t_list;

FETCH t_list INTO f_name, l_name;

DBMS_OUTPUT.PUT_LINE('Name = ' || f_name || ' '

|| l_name);

FETCH t_list INTO f_name, l_name;

DBMS_OUTPUT.PUT_LINE('Name = ' || f_name || ' '

|| l_name);

-- FETCH t_list INTO l_name; -- must have two variables

CLOSE t_list;

END;
