Use the TIB_Cursor component for all non buffered select statements. Call
the First method (which opens it, thus don't call open and then first) and
get your values from the Fields[0].AsInteger.

I suggest that you do rely on the IBO mechanisms to obtain a record count.
If your query needs special handling use the OnGetRecordCount event.

If there appears to be a problem in the IBO code, lets just get it fixed.
This sounds like a flag that is not being cleared when the count obtained
from the server becomes invalid. If an input parameter changes values it is
no longer holding a valid record count. Perhaps the TDataset layer is not
triggering that flag as it should. I'll be testing and fixing it soon.

This I'm not sure of. I use the * but if you are concerned about nulls (and
want them omitted) then you may want to include the column. I'm not a SQL
guru...

Well, if you help isolate it I can fix it right away. If I have to do the
work of isolating a case I am not yet fully in touch with I will be in the
hit and miss mode which I do tend to avoid having limited time and lots of
priorities to deal with.

Bear in mind I consider this important and I will isolate it if I have to...
