Thanks bitbucket for a nice question i learnt lot from this....

Slight problem, I think the question is incomplete:

1. In the text the table is referred to 'QOD_Customer' (singular), but in the SQL it is 'QOD_Customers' (plural)

2. There is no mention of the CompanyName column in the question.

The table name has been corrected. A complete DDL is not given. You should assume other fields mentioned do exist, but are not listed for brevity.

Can someone verify for me that this is different in SQL 2008 vs SQL 2005? I get a different result using 2005 (I don't have access to a 2008 server).

Thanks!

It appears that you should get the same result on SQL 2005 as SQL 2008.

I'm with Ernie on this. The rollback worked on 2005.

DDL and data inserted:

--drop table [QOD_Customers]

create table [dbo].[QOD_Customers](

ID int Identity

,[CompanyName] nChar(10)

,[Region] nChar(3) Null

)

insert into [QOD_Customers] (CompanyName,Region) values('ABC','YYY')

insert into [QOD_Customers] (CompanyName,Region) values('XYX', null)

Create stored procedure:

--drop procedure [QOD_Test_1]

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

CREATE PROCEDURE [dbo].[QOD_Test_1]

AS

SET ANSI_DEFAULTS ON

-- Before rollback Select Statement

SELECT COUNT(CompanyName) AS 'Before rollback'

FROM [dbo].[QOD_Customers]

WHERE [dbo].[QOD_Customers].[Region] IS NULL

UPDATE Dbo.QOD_Customers

SET Region = 'XXX'

WHERE dbo.QOD_Customers.region IS NULL

-- The after update Select Statement

SELECT COUNT(CompanyName) AS 'After update'

FROM [dbo].[QOD_Customers]

WHERE [dbo].[QOD_Customers].[Region] IS NULL

ROLLBACK TRANSACTION

SET ANSI_DEFAULTS OFF

-- The after rollback Select Statement

SELECT COUNT(CompanyName) AS 'After Rollback'

FROM [dbo].[QOD_Customers]

WHERE [dbo].[QOD_Customers].[Region] IS NULL

GO

Run it:

SET ANSI_NULLS ON

GO

SET QUOTED_IDENTIFIER ON

GO

SET ANSI_DEFAULTS ON

go

[dbo].[QOD_Test_1]

go

Results:

Before rollback

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

5

(1 row(s) affected)

(5 row(s) affected)

After update

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

0

(1 row(s) affected)

After Rollback

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

5

(1 row(s) affected)

When ANSI_DEFAULTS is enabled (ON), this option enables the following ISO settings:...SET IMPLICIT_TRANSACTIONS. Msg 3903 The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION.

The explanation doesn't quite make sense - I presume there are some words missing somewhere? Or is the quoting of the error message just assumed to be for information purposes? The explanation makes it look like it's one of the ISO settings 🙂

-------------------------------Oh no!

Yes it is.

Hope this clarifies it for you.
