I got an error:

Type dbo.HVCIDdt is not a defined system type.

WHY?

I think [HVCIDdt] is a user data type (just like Int or BigInt), we are supposed to create, but the tsql in the post does not have.

If you change [HVCIDdt] for [BigInt], the script works.

See details here.

Or you could create the user type -

CREATE TYPE [dbo].[HVCIDdt]

FROM bigint NOT NULL ;

I don't think you need the TOP 1 in the existence tests. EXISTS (SELECT...) already has the optimization of stopping after the first row built in.

This is a feature added in SQL Server 2012; that might be the problem for pawel.sowka.

Oh, that's why I don't know about it.
