Syntax
@@FETCH_STATUS
Return Types
integer
Remarks
Because @@FETCH_STATUS is global to all cursors on a connection, use @@FETCH_STATUS carefully. After a FETCH statement is executed, the test for @@FETCH_STATUS must occur before any other FETCH statement is executed against another cursor. The value of @@FETCH_STATUS is undefined before any fetches have occurred on the connection.
For example, a user executes a FETCH statement from one cursor, and then calls a stored procedure that opens and processes the results from another cursor. When control is returned from the called stored procedure, @@FETCH_STATUS reflects the last FETCH executed in the stored procedure, not the FETCH statement executed before the stored procedure is called.
Examples
This example uses @@FETCH_STATUS to control cursor activities in a WHILE loop.
DECLARE Employee_Cursor CURSOR FOR
SELECT LastName, FirstName FROM Northwind.dbo.Employees
OPEN Employee_Cursor
FETCH NEXT FROM Employee_Cursor
WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM Employee_Cursor
END
CLOSE Employee_Cursor
DEALLOCATE Employee_Cursor
