PRB: Specifying Table Name with Column Name in MFC DAO

• Microsoft Visual C++ 32-bit Edition, versions 4.0, 4.1

SYMPTOMS

If you add a table name qualifier to a column name in the DoFieldExchange of your CDaoRecordset-derived class where one is not required to resolve ambiguity, an exception will be thrown when the recordset is opened. The exception indicates that:

GetRows failed. The requested column is not a member of this recordset.

CAUSE

Specifying table name qualifiers for columns that are not ambiguous (where the column name is sufficient to uniquely identify the column) causes the assignment of retrieved data to bound columns that occurs in the GetRows function to fail.

RESOLUTION

Remove unnecessary table name qualifiers to avoid this behavior.

STATUS

This behavior is by design.
