T-SQL is a language to query and modify relational database. For this it is 
a very powerful language.

However, T-SQL is not a general-purpose language, and if you try to use it 
for something it is not intended, you will have to accept the raw edges.

If you want a smoother ride, move the administrative tasks to the client-
side language of your choice.
