Common lock types, such as Shared, Exclusive, and Update were explored, as well as using SP_Lock to obtain current system lock information. In this article, the normal internal SQL locking methods will be manipulated using Lock Hints in order to obtain finer lock control.

Throughout this and other of my series, we have examined parameterization and parameter picklist support. While my focus has often been support of picklists using datasets generated through MDX queries against the cube under consideration, I have often found myself in client engagement scenarios where differing reporting requirements, as well as various "exceptions," drive a need to extend picklist support beyond the capabilities of the basic MDX queries that we have examined.
