Description copied from interface: SetStore

Create a subquery for the given query that joins a SetStores element table to the owner table. This subquery can subsequently be used in an EXISTS expression to determine whether a Set is empty or not.

Specified by:

Parameters:

ownerIDColumn - The QueryColumn of the owner ID.

setRangeVar - The range variable for the "Set" table.

Returns:

A subquery for the given query that joins a SetStores element table to the owner table.
