You must add a range to the query and set its value.
For example, you can add the range in executeQuery() like this:
QueryBuildRange dateRange = SysQuery::findOrCreateRange(this.queryBuildDataSource(), fieldNum(MyTable, MyDateField));
This code either creates a new range, or it uses an existing one, if it exists.
Then you must set a value based on your dates. It might look like this:
Details depends on your particular situation.
