Yes, rdb$db_key, and version if needed. This would work only for a
single table selects though. Nickolay has better idea: to add new
isc_dsql_prepare with some flag, and if this flag set, return all
available rdb$db_key values in appropriate XSQLVAR fields at the end
of XSQLVAR block. This would work also for joins.

I hope that Nickolay can explain the problem here.
