SUMMARY

CDaoRecordset::GetRecordCount is not guaranteed to return the correct number of rows for a table-type recordset even if you call this function after calling MoveLast().

MORE INFORMATION

You can call CDaoRecordset::GetRecordCount to find out how many records in a recordset have been accessed. GetRecordCount does not indicate how many records are contained in a dynaset-type or snapshot-type recordset until all records have been accessed. To force the last record to be accessed, call the MoveLast function.

The value of GetRecordCount from a table-type recordset reflects the approximate number of records in the table.

To get an accurate record count, open a dynaset- or snapshot-type recordset and then do a MoveLast. Table-type recordsets will be accurate immediately after the database has been compacted or repaired.
