Need To Convert This Sql Query For Access To Identical Sql Query For Sql 2005..

My code retrieves a username and a password from a form. Then this information is compared to some usernames and passwords that are stored in a database. The important thing here is that the comparison must be case sensitive meaning that "passWord" is not the same thing as "password"

I have this code, working fine in access 2003

SQL = "SELECT * FROM users WHERE StrComp(username_column,'" & entered_username_in_form & "',0) = 0 AND StrComp(password_column,'" & entered_password_in_form & "',0) = 0"

but get the following error when I run it against my sql 2005 database.

[Microsoft][SQL Native Client][SQL Server]'StrComp' is not a recognized built-in function name.

I don't know the corresponding t-sql for the query.
