Why do I have to raise raiserror in SQL Server stored procedure?

To add a new user-defined error message number, you use the stored procedure sp_addmessage. A user-defined error message number should be greater than 50,000. By default, the RAISERROR statement uses the message_id 50,000 for raising an error.

What’s the difference between Transact-SQL print and raiserror?

RAISERROR supports character substitution similar to the functionality of the printf function in the C standard library, while the Transact-SQL PRINT statement does not. The PRINT statement is not affected by TRY blocks, while a RAISERROR run with a severity of 11 to 19 in a TRY block transfers control to the associated CATCH block.

Is there a better way to use raiserror?

My only choice seems to be using a TRY…CATCH block to wrap the IF clause and rethrow the RAISERROR from within the CATCH block, which is awkwards because then I will have to cache ERROR_MESSAGE (), ERROR_SEVERITY () and ERROR_STATE () and use RAISERROR once again. Isn’t there really any more elegant way?
