Whenever I do something really stupid, rather than keep it to myself, I prefer to blog about it for the entire world to see. Even better – I came up with a debugging technique to save myself from my own, er, stupidity.The scenario is this: I am developing some SQL Server Analysis Services Date Calculations […]

The main two applications that are used for Microsoft-centric development are Business Intelligence Development Studio (BIDS) and SQL Server Management Studio (SSMS). There are a few add-on utilities that increase the power and usefulness of the out of the box applications. I find these invaluable: MDXStudio – the brilliant Mosha Pasumansky‘s take on how MDX development should […]
