How to throw exception from SQL server 2005 function?

问题

When I try to use RaiseError, I get the following compilation issue

Msg 443, Level 16, State 14, Procedure ConvertSessionToCurr, Line 19 Invalid use of a side-effecting operator 'RAISERROR' within a function.

So how do we handle exception in a function/ Change it to a out param stored proc? That really sounds like a bummer!

回答1:

Options:

• Return NULL or some sentinel value
• Use a stored procedure
• Make it inline code

My thought is that if you need RAISERROR in a UDF you're using it wrong...
