FIX: Error when you update an ADO client-side recordset when data source does not support schemas

Article ID: 839411

Article Last Modified on 4/7/2006

APPLIES TO

Microsoft ActiveX Data Objects 2.7
Microsoft Data Access Components 2.7 Service Pack 1

SYMPTOMS

When you update a row in a Microsoft ADO client-side recordset, you receive the following error message:

Insufficient base table information for updating or refreshing.

CAUSE

To update data in a client-side cursor, ADO generates an UPDATE statement that is executed against the data source. When you are using the Microsoft OLE DB Provider for ODBC (MSDASQL) with an ODBC driver that does not support schemas, and the table name in your original statement is enclosed in double quotation marks, ADO may incorrectly determine the table name to use in the UPDATE statement. Therefore, the error occurs
