UPDATE and DELETE Requirements for OLE DB Providers

SQL Server 2000

Transact-SQL UPDATE and DELETE statements can reference remote tables only if the following conditions are met by the OLE DB provider that is used to access the remote table:

  • The provider must support bookmarks on the rowset opened through IOpenRowset on the table being updated or deleted.

  • The provider must support the IRowsetLocate and IRowsetChange interfaces on the rowset opened through IOpenRowset on the table being updated or deleted.

  • The IRowsetChange interface must support update (SetData) and delete (DeleteRows) methods.

The Microsoft OLE DB Provider for SQL Server supports these interfaces only on a table that has a unique index. Consequently, UPDATE or DELETE statements are permitted against a remote table in another instance of Microsoft® SQL Server™ only if the table has a unique index.
