SYMPTOMS
With the Microsoft Jet 4.0 ODBC driver, a call to the SQLBulkOperations ODBC function, when preceded by a call to SQLExtendedFetch, may result in the following error:

DIAG [S1010] [Microsoft][ODBC Driver Manager] Function sequence error (0)



CAUSE
Earlier versions (3.5x) of the Jet ODBC drivers do not implement SQLBulkOperations. If an application uses this function with these versions, the ODBC Driver Manager changes the call to SQLSetPos, which does not produce this error when preceeded by SQLExtendedFetch.

Because version 4.0 of the Jet driver implements SQLBulkOperations, the call is not transformed by the Driver Manager. Instead, it is passed unchanged to the driver, which results in the error.

NOTE: The ODBC documentation expressly states that the combination of SQLExtendedFetch followed by SQLBulkOperations will result in a function sequence error.



RESOLUTION
Replace the SQLExtendedFetch call with a call to SQLFetchScroll.
