Error when filtering on a _make_timestamp column
You cannot filter on a _make_timestamp column. If you do that, the following error
messages appear:
UDA-SQL-0114 The cursor supplied to the operation "sqlOpenResult" is inactive
UDA-SQL-0206 The OLEDB driver returned the following value: HRESULT= DB_E_CANTCONVERTVALUE
RSV-SRV-0025 Unable to execute this request
The solution is to apply the filter after aggregation, and not before.
