An ODBC error has occurred. Visual FoxPro provides this message as a wrapper for the actual ODBC error. The ODBC error can be generated by the ODBC driver manager, by the ODBC driver, or by the back-end data server. AERROR(В ) returns the ODBC errors. The format of an ODBC error 1526, as returned by AERROR(В ), is as shown in the following table.
