TEM Server upgrade fails
Database Collation changed, either on the entire database or individual tables
Microsoft SQL Server
Resolving the problem
To Check to see what your collations are, you may need assistance from your DBA.
There are three possible places where collation could be changed that should be double checked, and make sure that they are all set to be the same value. Run the following SQL Server Queries, from the SQL Server Management Studio;
1. At the SQL server instance level
2. At the database level.
SELECT DatabasePropertyEx( 'BFEnterprise', 'Collation' )
3. At the column level in the database, some of the system columns might be in a different collection.
SELECT C.name, O.name, C.collation_name
from BFEnterprise.sys.columns C, BFEnterprise.sys.all_objects O
where C.collation_name is not NULL
and C.object_id = O.object_id
If the Server collation is different from the database collation and/or the collation of the columns in the database. You must manually correct the collation, they must all be the same.
As a standard configuration, use the CI - Case Insensitive collation setting, if you us the CS - Case Sensitive collation, there will be issues with mixed case characters.
Collation setting Example;
Case Insensitive Collation uses SQL_Latin1_General_CP1_CI_AS - (use this one for TEM)
Case Sensitive Collation uses SQL_Latin1_General_CP1_CS_AS
You can change the collation for the server, database, and columns using the instructions at
