Force T-SQL query to be case sensitive in MS

Question

I have a table that originates in an old legacy system that was case senstive, in particular a status column where 's' = 'Schedule import' and 'S' = 'Schedule management'. This table eventually makes its way into a SQL Server 2000 database which I can query against. My query is relatively simple just going for counts...

Select trans_type, count(1) from mytable group by trans_type

This is grouping the counts for 'S' along with the 's' counts. Is there any way to force a query to be cap sensitive? I have access to both SQL Server 2000 and 2005 environments to run this, however have limited admin capability on the server (so I can't set server attributes)... I guess I could move the data to my local and setup something on my local where I have full access to server options, but would prefer a tsql solution.

Answer 1

select trans_type collate SQL_Latin1_General_CP1_CS_AS, count(*)
from mytable
group by trans_type collate SQL_Latin1_General_CP1_CS_AS

You can do this with =, like, and other operators as well. Note that you must modify the select list because you are no longer grouping by trans_type, you are now grouping by trans_type collate SQL_Latin1_General_CP1_CS_AS. Kind of a gotcha.

Answer 2

Can you introduce a trans_type_ascii column with the ascii value of the trans_type and group on that instead? Or any other column you can use (isUpperCase) to distinguish them.
