Expand all | Collapse all

Symptoms

Query performance may be slow when all of the following conditions apply:
  • Either Service Pack 1 or Service Pack 2 is installed on the SQL Server.
  • You are not logged in as a System Administrator.
  • You execute a query that causes a trigger to be fired.
  • The trigger directly accesses the INSERTED or DELETED trigger tables.

Cause

Inaccurate row estimates for the INSERTED and DELETED tables are used prior to Service Pack 3, which results in suboptimal table scans instead of index seeking when the user is not a System Administrator.

Status

Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
