@@TRANCOUNT

Returns the number of active transactions for the current connection.

Syntax

@@TRANCOUNT

Return Types

integer

Remarks

The BEGIN TRANSACTION statement increments @@TRANCOUNT by 1. ROLLBACK TRANSACTION decrements @@TRANCOUNT to 0, except for ROLLBACK TRANSACTION savepoint_name, which does not affect @@TRANCOUNT. COMMIT TRANSACTION or COMMIT WORK decrement @@TRANCOUNT by 1.

Examples

This example uses @@TRANCOUNT to test for open transactions that should be committed.

BEGIN TRANSACTION
UPDATE authors SET au_lname = upper(au_lname)
WHERE au_lname = 'White'
IF @@ROWCOUNT = 2
   COMMIT TRAN

IF @@TRANCOUNT > 0
BEGIN
   PRINT 'A transaction needs to be rolled back'
   ROLLBACK TRAN
END
