Comentários

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

When data is transferred to a computer running an instance of SQL Server version 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 the code page of the source to the code page of the destination. If both computers are running 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 nondefault collation.

ObservaçãoObservação

Setting UseCollation to true can result in a decrease in performance 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.
