In really, is a practical question. 

I have to classify some records (about 300k) in many categories (nearly 200). 
So, I thought do this directly in the select statement (using case clause). 
However, write a query with 200 conditions "when ... then..." to, at the end, 
the debugger tell you that you reached the conditions limits is kind annoying.

Thanks.
