======================================================================
-------------------------------------------------------------------------------

BUG #: 16050 (sql server: 6.5)

SYMPTOMS
========

When an ODBC application uses a SQLStatistics function call to retrieve the
index information associated with the views, the SQLStatistics function does not
return any index information for the views.

When Microsoft Access database users create link tables to SQL Server tables
using SQL Server data sources, the SQL Server ODBC Driver uses SQLStatistics to
automatically retrieve the index information and set up the link tables, without
prompting the users to select a unique index for the tables.

Microsoft Access database users may be prompted to select the unique index record
identifier when they create link tables to SQL Server views, because
SQLStatistics does not return any information associated with the views.

CAUSE
=====

SQLStatistic uses the Microsoft SQL Server stored procedure sp_statistics to
retrieve the unique index information, and sp_statistics does not return unique
index information for views.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft SQL Server version
6.5, Open Database Connectivity 2.5, and ODBC Driver version 2.65. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
