COUNT(column) Support

COUNT(column) Support is an advanced property that is hidden by default. For information on how to display this property, see Viewing and Changing Advanced VLDB Properties.

The COUNT(column) Support property is used to specify whether COUNT on a column is supported or not. If it is not supported, the COUNT(column) is computed by using intermediate tables and COUNT(*).
