Great article Nakul.

Another use of the Checksum is for the hash index creation. When indexes are created over nvarchar or varchar datat type columns, CHECKSUM() hashes the value. This could help in over-riding the 900 byte limit posed during the index creation.

Hello,
Thanks for great article. I have one question.
Example "CHECKSUM may fail to detect a change" works diffrent on my SQL Server. It returns:

Before Change | After Change
-546463845 | 991901348

Is it connected with collation?
