PRSQL9103011: Duplicate Values with a Unique Clustered Index ID Number: Q70831

1.10 OS/2 buglist1.10 fixlist1.11

Summary:

PROBLEM ID: PRSQL9103011

SYMPTOMS An update within a transaction is allowed to create a duplicate value on a column with a unique clustered index. In addition, paging errors occur on the index.

CAUSE This problem is a result of using a clustered index on the table referenced within the transaction.

WORKAROUND Drop and re-create the index to remove the paging errors. Use a nonclustered index instead of a clustered index to avoid this problem.

STATUS Microsoft has confirmed this to be a problem in SQL Server version 1.1. This problem has been corrected in SQL Server version 1.11, which is available from Microsoft Product Support Services. For more information, contact your primary support provider.
