Remarks

By default, UseCollation is set to FALSE.

If UseCollation is set to TRUE, column-level collation settings are maintained when transferring data between computers running an instance of SQL Server 2000 if the code pages are the same on both servers. When transferring data to a computer running an instance of SQL Server 2000 using a different code page, all collation settings at the source computer are automatically translated to the code page of the destination server if the code pages settings are different.

When transferring data to a computer running an instance of SQL Server 7.0 or earlier, all collation settings at the source server are automatically translated to the code page of the destination server if the code pages settings are different. The source database column-level collation is translated accordingly.

If UseCollation is set to FALSE, direct data transfer is performed if the code pages are the same on both servers. If the code pages are different, the data is translated from source code page to destination code page. If both computers are running an instance of SQL Server 2000 and the source and destination databases are using different code pages, data might be translated to the incorrect code page setting depending on whether the column is using the default or a non-default collation.

Note  Setting UseCollation to TRUE can result in a increase in performance overhead if the data contains non-Unicode data types such as text or varchar. Performance can also be affected by the number of tables, columns, and rows in the source database.

Note  If an application calls UseCollation on an instance of SQL Server version 7.0, the operation is ignored.
