SYMPTOMS

Upon executing a query including a join, with or without NOEXEC set, the following dialog box appears:

SQLSERVR.EXE: The exception Floating-point invalid operation
(0xc0000090) occurred in the application at location 0x00567938.
Click on OK to terminate the application Click on CANCEL to debug
the application.

If OK is chosen, the entire SQL Server process is terminated. This happens only on Alpha processors.

CAUSE

A floating-point underflow has occurred while the optimizer was evaluating possible join orders.

WORKAROUND

It may be possible to avoid this problem by changing the number or type of indexes available to the optimizer. The problem may disappear when there is a change in the distribution of data in the tables and UPDATE STATISTICS is run.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 4.21a. This problem was corrected in the latest U.S. Service Pack for SQL Server version 4.21a. For information on obtaining the Service Pack, please contact your primary support provider.
