Poorly Performing Unicode Query

The main performance issue is performaing the "N" function infront of the strings in the where clause. I get 20x-45x perfromance boost by removing it, but unfortunately my reporting tool doesn't allow me that option.

Anything I can do on the DB end to solve this? The DB is not unicode.

Hi,

I recommend that you post your question on the Transact-SQL forum. The Documentation forum is usually not the best spot for code-specific questions.
