So, in a nutshell, it is not the case of one being better than the other. Depending on your circumstances, you should probably be using both on the same table, just of different columns. I would say however, do not put nonclustered indexes on lots of columns, because they can slow do...

We have decided to create three tables with six columns each. In addition, we added keys. Below we present the SQL-code of creating a relational database structure, which is used in our experiments. By default with relational database creation, we get indexes and constraints. If we compare...
Instantly map many tables as one. AMERGEtable need not maintain an index of its own because it uses the indexes of the individual tables. As a result,MERGEtable collections areveryfast to create or remap. (You must still specify the index definitions when you create aMERGEtable, even though...
