FIX: Java OLE DB Simple Provider Crashes in Recordset.Delete() Method

• Microsoft Data Access Components version 2.1 (GA)
• OLE DB Simple Provider Toolkit, version 2.0
• Microsoft Visual J++, version 6.0
• Microsoft Data Access SDK, versions 2.0, 2.01, 2.1

SYMPTOMS

When using the OLE DB Simple Provider for Java, and when using the Recordset.Delete method, the following errors occur depending on the language that the recordset is used from:

In Visual C++

Unhandled exception in <program.exe> (MSDAOSP.DLL): 0xC0000005: Access Violation

In Visual Basic or Visual J++

The instruction at "<hex address>" referenced memory at "0x00000000". The memory could not be "read".

CAUSE

This error is caused by an attempt to use an invalid rowset interface within DeleteRowsetHelper.

RESOLUTION

This problem has been fixed with Microsoft Data Access Components (MDAC) 2.1 Service Pack 2 (SP2). You can download MDAC 2.1 SP2 from the following Microsoft Universal Data Access Web site:
