The extra column will have the identity property, and will be included on all indexes that are not unique. Otherwise, when A_MSSQL_ADD_IDENTITY is set at "False", an extra column is not added.
A_MSSQL_ADD_IDENTITY TRUE
On keys that allow duplicates, this variable has been found to vastly improve performance. Note that the default value is "True" for a file that allows duplicates, and is "False" for a file with no duplicate keys.
While the default value is "On" (true, yes), this configuration variable can also take values of "Off" (false, no).
