If that is a requirement, you could easily make it thread-safe by using locks. Shaun, this implementation is a simple one and is not thread-safe.

What if something subscribes while the foreach is executed within the publish? Thanks, Shaun Brent, is this thread safe? What if something subscribes while the foreach is executed within the publish?

Thanks,

You definitely need all the messages published through the same instance. Whether you make it a singleton or have your inversion of control container keep it as a singleton (as I like to do), the important thing is that the same instance is used everywhere. @InterestedParty Yep.

It causes problem when working with large amounts of data. The reason is SQL Server may evaluate BOTH sides of the OR clause causing a hit on performance (view your execution plan). A much better way would be to use: T.CategoryID = ISNULL(@CategoryID,T.CategoryID) Ensure good database design that does not allow T.CategoryID to be null and you're all set. Hello,
