BUG #: 4841 (Brazos)
SYMPTOMS
========
If an application does the following in the Microsoft Access 7.0 or 97 version
of the ODBC drivers more than seven times
SQLSetConnectOption(hdbc, SQL_AUTOCOMMIT, SQL_AUTOCOMMIT_OFF);
SQLTransact(henv, hdbc, SQL_COMMIT);
The error generated is:
*szSqlState = "S1000", *pfNativeError = -1103,
*szErrorMsg = "[Microsoft][ODBC Microsoft Access 97 Driver] "
If the application calls SQLExecDirect with any SQL statement, the error
generated is:
szSqlState = "S1000", *pfNativeError = -1103, *pcbErrorMsg = 110
szErrorMsg="[Microsoft][ODBC Microsoft Access 97 Driver] Couldn't start
transaction; too many transactions already nested."
WORKAROUND
==========
To work around this problem, do not set the SQL_AUTOCOMMIT option repeatedly
within a connection. The SQL_AUTOCOMMIT option is a per-connection option. Once
this option is set, it stays valid until the connection is dropped; an ODBC
application does not have to set the option repeatedly within a connection.
STATUS
======
Microsoft has confirmed this to be a problem in the Microsoft Access ODBC driver
version 3.50.3602. We are researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
