SQL Server check case-sensitivity?

Collation can be set at various levels:

  1. Server
  2. Database
  3. Column

So you could have a Case Sensitive Column in a Case Insensitive database. I have not yet come across a situation where a business case could be made for case sensitivity of a single column of data, but I suppose there could be.

Check Server Collation

SELECT SERVERPROPERTY('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
