You will need to consider at least two paths before deciding to virtualize any of your SQL Servers. The first path is to think about why you are virtualizing your systems; consider the advantages and disadvantages a virtual environment provides. Some of these advantages and disadvantages ar...
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...
you want to take advantage of the features specific to the statement-based or row-based replication format when performing certain tasks, you can use the information in this section, which provides a summary of their relative advantages and disadvantages, to determine which is best for your needs...

In a mysql context it can get important when working with indexes on said varchar columns, as mysql has a max. limit of 767bytes per index-row. This means that when adding a index across several varchar 255 columns you can get to this limit rather quickly / even faster o...
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...
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 no indexes are created.)...
