FIX: UNION in Views Maintains Duplicate Rows If Table Has Bit

• Microsoft SQL Server version 6.5

SYMPTOMS

Running a SELECT from a view that is defined as a UNION of select statements does not eliminate duplicate rows, if the underlying table contains a field of the bit type. However, duplicate rows are eliminated if the UNION statement is not within a view.

WORKAROUND

If the bit datatype must be used, place the UNION statement outside a view, or use the DISTINCT keyword when selecting from the view. Otherwise, use tinyint, smallint, or int datatypes rather than the bit type.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.
