Arguments

'local'
Specifies a constant indicating that the cursor source is a local cursor name.

'cursor_name'
The name of the cursor. A cursor name must conform to the database identifier rules.

'global'
Specifies a constant indicating that the source of the cursor is a global cursor name.

'variable'
Specifies a constant indicating that the source of the cursor is a local variable.

'cursor_variable'
The name of the cursor variable. A cursor variable must be defined using the cursor data type.

Return types

smallint

Return value	Cursor name	Cursor variable
1	The cursor result set has at least one row. For insensitive and keyset cursors, the result set has at least one row. For dynamic cursors, the result set can have zero, one, or more rows.	The cursor allocated to this variable is open. For insensitive and keyset cursors, the result set has at least one row. For dynamic cursors, the result set can have zero, one, or more rows.
0	The cursor result set is empty.*	The cursor allocated to this variable is open, but the result set is definitely empty.*
-1	The cursor is closed.	The cursor allocated to this variable is closed.
-2	Not applicable.	Has one of these possibilities: The previously called procedure did not assign a cursor to this OUTPUT variable. The previously assigned procedure assigned a cursor to this OUTPUT variable, but the cursor was in a closed state when the procedure completed. Therefore, the cursor is deallocated, and not returned to the calling procedure. No cursor is assigned to the declared cursor variable.
-3	A cursor with the specified name does not exist.	A cursor variable with the specified name does not exist, or if one exists, no cursor is yet allocated to it.

*Dynamic cursors never return this result.

Examples

This example uses the CURSOR_STATUS function to show the status of a cursor, after its declaration, after it opens, and after it closes.

CREATE TABLE #TMP  
(  
   ii INT  
)  
GO  
  
INSERT INTO #TMP(ii) VALUES(1)  
INSERT INTO #TMP(ii) VALUES(2)  
INSERT INTO #TMP(ii) VALUES(3)  
  
GO  
  
--Create a cursor.  
DECLARE cur CURSOR  
FOR SELECT * FROM #TMP  
  
--Display the status of the cursor before and after opening  
--closing the cursor.  
  
SELECT CURSOR_STATUS('global','cur') AS 'After declare'  
OPEN cur  
SELECT CURSOR_STATUS('global','cur') AS 'After Open'  
CLOSE cur  
SELECT CURSOR_STATUS('global','cur') AS 'After Close'  
  
--Remove the cursor.  
DEALLOCATE cur  
  
--Drop the table.  
DROP TABLE #TMP
