In Microsoft SQL Server 2005, you open a fast forward-only cursor for a query. When you run the query, you cannot cancel the query execution immediately. It may take a long time to cancel the query.
Additionally, you may also receive the following error message:
[SQL Native Client] Communication link failure
This issue does not occur in Microsoft SQL Server 2000.
This problem occurs because an attention signal is sent to the server when you cancel the query. When the SQL Server Database Engine performs an index scan for the query, the SQL Server Database Engine does not check for the attention signal immediately.
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.
