In a previous article, I discussed Merge statement basics. However, in extensive testing I’ve come to realize that my article, like most articles I’ve read about Merge leaves out or mis-handles several important aspects.

For those who don’t know, I’m currently the Data Warehouse Architect for a large scale and complex multi-tenant data warehousing project. Fortunately, the project is being created in SQL Server 2012 and I thrilled to be using the new features. Let me preface this blog post by admitting that my experience with using the SSIS [...] Those who read this blog know that I’ve always been into the PASS Community, particularly about attending the PASS Summit.
