BUG: Calling IDBInfo::GetKeywords() Causes AV with OLE DB Provider for ODBC (MSDASQL)

• Microsoft Open Database Connectivity, versions 3.5, 3.51, 3.6, 3.7

SYMPTOMS

ODBC drivers that return keywords outside the range of Absolute to Zone cause an access violation in the Microsoft OLEDB Provider for ODBC (MSDASQL) when the IDBInfo::GetKeywords() method is called.

CAUSE

This occurs because of a code problem in the binary search algorithm used by MSDASQL.

RESOLUTION

To work around this behavior, modify the driver so that it does not return keywords outside the range Absolute - Zone.

For example, if the driver returns the keyword Abort, the Microsoft OLEDB Provider for ODBC (MSDASQL) gets an access violation.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION
