Because all Unicode systems consistently use the same bit patterns to represent all characters, there is no problem with characters being converted incorrectly when moving from one system to another. The easiest way to manage character data in international databases is always to use the Unicodenchar...
As a rule, you should always have a clustered index defined on a table. Doing so improves Microsoft SQL Server performance and space management. If you do not know the query or update patterns for a given table, you can default to using the clustered index on the primary key. Later ...
