FIX: Derived Table Generation May Cause Error 206

ID: Q158807

The information in this article applies to:

Microsoft SQL Server version 6.5

BUG #: 15800 (6.50)

SYMPTOMS

If a query used to create a derived table selects a user-defined datatype, selecting from the derived table may cause the following error message:

206 16 Operand type clash: %s is incompatible with %s

The following example shows a query that may cause this problem. In the example, au_id from the authors table is a user-defined datatype.


   use pubs
   go
   select * from (select a.au_id from authors a
   inner join titleauthor ta on a.au_id = ta.au_id
   and a.au_fname = "Albert") as a
   go

WORKAROUND

To work around this problem, do not use derived tables to select data from columns with user-defined data types.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.50. 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.
