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.

USE AdventureWorks;
GO
BEGIN TRANSACTION;
GO
UPDATE Person.Contact
    SET LastName = UPPER(LastName)
    WHERE LastName = 'Wood';
GO
IF @@TRANCOUNT > 0
BEGIN
    PRINT N'A transaction needs to be rolled back.';
    ROLLBACK TRANSACTION;
END
