You can use this function along with the ODBCIsBOF function to determine whether the record set contains any records or is empty. Immediately after calling the ODBCQuery function, and if the record set contains no records, ODBCIsBOF returns non-zero. When you open a record set with at least one record, the first record is the current record and ODBCIsEOF returns a zero (0). If the last record is the current record, and you call ODBCMoveNext, ODBCIsEOF will subsequently return a non-zero.
