to do rollback in a right way,

I wrote:

-----------------

BEGIN Tran t1

DROP TABLE T

go

ROLLBACK

GO

----------------

SELECT * FROM T

The transaction was used before cross the word "go" so,

---------------------------------

BEGIN Tran t1

DROP TABLE T

ROLLBACK

Tran GO

---------------------------------

rollback doesn't raw
