SET CURSOR_CLOSE_ON_COMMIT
Controls whether or not a cursor is closed when a transaction is committed.
Syntax
SET CURSOR_CLOSE_ON_COMMIT { ON | OFF }
Remarks
When SET CURSOR_CLOSE_ON_COMMIT is ON, this setting closes any open cursors on commit or rollback in compliance with SQL-92. When SET CURSOR_CLOSE_ON_COMMIT is OFF, the cursor is not closed when a transaction is committed.
When SET CURSOR_CLOSE_ON_COMMIT is OFF, a ROLLBACK statement closes only open asynchronous cursors that are not fully populated.STATIC or INSENSITIVE cursors that were opened after modifications were made will no longer reflect the state of the data if the modifications are rolled back.
SET CURSOR_CLOSE_ON_COMMIT controls the same behavior as the cursor close on commit database option of sp_dboption. If CURSOR_CLOSE_ON_COMMIT is set to ON or OFF, that setting is used on the connection. If SET CURSOR_CLOSE_ON_COMMIT has not been specified, the cursor close on commit setting of sp_dboption applies.
The Microsoft OLE DB Provider for SQL Server and the SQL Server ODBC driver both set CURSOR_CLOSE_ON_COMMIT to OFF when they connect. DB-Library does not automatically set the CURSOR_CLOSE_ON_COMMIT value.
When SET ANSI_DEFAULTS is ON, SET CURSOR_CLOSE_ON_COMMIT is enabled.
The setting of SET CURSOR_CLOSE_ON_COMMIT is set at execute or run time and not at parse time.
Permissions
SET CURSOR_CLOSE_ON_COMMIT permissions default to all users.
Examples
This example defines a cursor in a transaction and attempts to use it after the transaction is committed.
SET NOCOUNT ON
CREATE TABLE t1 ( a int )
GO
INSERT INTO t1 values (1)
INSERT INTO t1 values (2)
GO
PRINT '-- SET CURSOR_CLOSE_ON_COMMIT ON'
GO
SET CURSOR_CLOSE_ON_COMMIT ON
GO
PRINT '-- BEGIN TRAN'
BEGIN TRAN
PRINT '-- Declare and open cursor'
DECLARE testcursor CURSOR FOR
SELECT a
FROM t1
OPEN testcursor
PRINT '-- Commit tran'
COMMIT TRAN
PRINT '-- Try to use cursor'
FETCH NEXT FROM testcursor
CLOSE testcursor
DEALLOCATE testcursor
GO
PRINT '-- SET CURSOR_CLOSE_ON_COMMIT OFF'
GO
SET CURSOR_CLOSE_ON_COMMIT OFF
GO
PRINT '-- BEGIN TRAN'
BEGIN TRAN
PRINT '-- Declare and open cursor'
DECLARE testcursor CURSOR FOR
SELECT a
FROM t1
OPEN testcursor
PRINT '-- Commit tran'
COMMIT TRAN
PRINT '-- Try to use cursor'
FETCH NEXT FROM testcursor
CLOSE testcursor
DEALLOCATE testcursor
GO
