Any query, without valmode: "LONG" the datatypes of the returned
values from, e.g.
SQLGetDescField(hdesc, column, SQL_DESC_COL_DV_TYPE, &dvtype,
SQL_IS_INTEGER, NULL);
seems to always be VIRTUOSO_DV_STRING. Which means for IRIs
I have to do a second query with __ro2sq to resolve them to
their string representation...

Ok, that's clear enough. Need to do a second API call when
we find a date to find out what kind of date or time it is.
