Syntax
ODBCIsEOF(numHandler)
- numHandler
- The handler returned by the
ODBCOpen function.
Returned value
| 0 |
Record
found. |
|
non-zero |
Record
set contains no records or you moved forward, after the last
record. |
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.
