I asked this question yesterday:
http://www.experts-exchange.com/Programming/Programming_Languages/Dot_Net/VB_DOT_NET/Q_22047143.html

That was a test code: testing my DAL Layer.

What I have is a class in BLL which calls a stored proc. The BLL is calling DAL for database connectivity stuff....

I was thinking about it...that class should be in DAL ..correct? I think DAL should call a stored proc, result is passed to BLL and BLL does whatever it needs to do and pass the result back to UI...

I dont think it's correct to have code in BLL to call stored procs or call database directly..is this correct?

I'd stick with the DAL for DB connectivity.

The test procedure you have in your DAL - is it just for testing purposes and will be removed before packaging. If so, you can look into using nUnit and other testing add-ons for VS. They will allow you to create a new project so keep any DB connectivity outside of the BLL.

I do have database connectivity outside BLL, in DAL.

BUT, I have the test stored proc in my BLL not in DAL...and that's what i want to know moving forward...

Should I call stored proc/database "select"/"update"/"insert" from DAL or from BLL?

yes, I would keep it in the DAL.

I'm a bit confused, what's the test stored procedure for?

The test stored proc was to see if I can get results back from the DAL and if it connencts to SQL Server and IBM iSeries...

Then i thought about the 3-tier and was wondering where the stored proc belongs...

Never used nUnit, will look into to.
thanks
