The following example uses @@FETCH_STATUS to control the WHILE loop in a typical cursor application:

-- T-SQL cursor declaration

DECLARE curManager CURSOR FOR

SELECT EmployeeID,

Title

FROM AdventureWorks.HumanResources.Employee

WHERE Title LIKE '%manager%'

OR Title LIKE '%super%';

OPEN curManager;

FETCH NEXT FROM curManager;

WHILE @@FETCH_STATUS = 0

BEGIN

PRINT 'Cursor loop'

FETCH NEXT FROM curManager;

END; -- while

CLOSE curManager;

DEALLOCATE curManager;

/* Partial results

EmployeeID Title

3 Engineering Manager

EmployeeID Title

6 Marketing Manager

However, the @@FETCH_STATUS is global to all cursors on a connection, therefore using @@FETCH_STATUS to control nested cursors may not be advisable. To play it safe for the case of following triple nested cursors demonstration, we avoid using @@FETCH_STATUS. Instead we order the SELECTs for the cursor and find the max value on one unique column. We use a comparison between the running values and maximum value to control the loop. The OUTER cursor loop is based on OrderDate. The MIDDLE cursor loop is based PurchaseOrderID-s received on a particular date. The INNER cursor loop is based on the products belonging to a particular PurchaseOrderID.
This is the entire triple nested cursors T-SQL script:
