OMG! I've worked with SQL Server for over 10 years and I've never heard of assertions. Really. This is the first time I hear there is something like that in SQL Server. Maybe I am the idiot w00t

Neither SQL Server, Oracle Nor MYSQL support Assertions either;

it think this is one of those Things Celko thought was great in theory and injected into some obscure ANSI standard, but noone else thought it worthy, and ignored implementing it.

While there are asserts in SQL, they are not something that you can create, they're a query plan operator only, so unless you spend time diving into query plans, you'll never see them.

Assertions are more commonly associated with front end languages, as in
http://msdn.microsoft.com/en-us/library/system.diagnostics.debug.assert%28v=vs.100%29.aspx

Please take the language and the random insults elsewhere, they have no place on a professional forum.
