SQL Server Case SEnSitiviTy

Potentially fraught if someone changes the collation setting on you.

Collation can be set at various levels:
  1. Server
  2. Database
  3. Column

Check Server Collation
Check Database Collation
SELECT DATABASEPROPERTYEX('AdventureWorks', 'Collation') SQLCollation;
Check Column Collation
select table_name, column_name, collation_name
from information_schema.columns
where table_name = @table_name
What the Result Means
Typically, you'll get SQL_Latin1_General_CP1_CI_AS.  
The CI part means CASE INSENSITIVE. SQL_Latin1_General_CP1_CI_AS.

If it was case SENSITIVE, it would be 'CS' instead of 'CI':
