DrillThroughColumns (MDStore Interface)
This feature will be removed in the next version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible.
The DrillThroughColumns property of the MDStore interface contains a list of columns that will be included in a drillthrough query.
The format of the string is identical to the format of the column list contained in an SQL SELECT clause. It includes the ability to define aliases. The format of the string in this property is provider-specific; it must be formatted according to the rules of the data source associated with the cube or partition.
