Hi Mark,

There's nothiong worng with your SELECT query ; the
problem is in the ODBC database driver not always
returning the correct record count. I've seen this
with Access and Progress databases as well.

Hopefully, the next revision opf the database drivers
will improve on this problem. The easiest workaround
for now is to traverse the record set until
revdb_iseof() returns true.
--
repeat until revdb_iseof(tCursorID)
  get revdb_movenext(tCursorID)
  ## do something with the data in the currentrecord
end repeat
--

Unfortunately, some databases only support read-only
forward-only cursors -- so you should traverse the
record set and fetch all the data you want in one go.

Hope this helped,

Jan Schenkel.
