Search for lowercase instances in a case-insensitive column

I have a table in my SQL Server 2005 database that contains customer IDs.  Example:

and so on.  I need to be able to identify anytime there's an entry of any lower case entry, separate from the correct entry of all upper case.  My database is set as case-insensitive but the application that uses it interprets the data differently if it is lower case rather than all upper case.

So in the set shown above, I'd just be looking for culsta2 and aqucon, and NOT CULSTA2 or AQUCON.

Anytime you use it, you could send it as UPPER(ID).

oops. misread what you wrote.  You can use a query like this:

select * from yourtable where cast(ID as varbinary(100)) <> cast(upper(ID) as varbinary(100))

and your varbinary can be as small as your IDs are
