Comparing string values in SQL Server that are case sensitive?

I have a datatable in a SQL Server 2008 DB that contains "Unit of Measurement" abbreviations. In some cases there are 2 abbreviations with the same characters, however they mean different things. Here is an example:


Is there a way to make a comparison in SQL Server that can treat each value differently. My problem is that I'm returning 2 rows instead of 1.

Add a COLLATE clause after one or both values to force a case-sensitive comparison.

For example:

    SELECT 'N.Mm'
) AS codes
    code = '' COLLATE Latin1_General_CS_AS
    --naturally comment out the COLLATE clause to see the difference
