View products that this article applies to.

BUG #: 364091 (SHILOH_BUGS)

SYMPTOMS

After you upgrade from SQL Server 2000 to SQL Server Service Pack 3 (SP3), a query that contains an ORDER BY clause and performs a SELECT INTO or INSERT SELECT query against a linked server may be incorrectly remoted as a Sub-SELECT function. If the linked server provider does not support Sub-SELECT functions, the provider may generate an error. The error you receive (that the provider generates) depends on the provider.

MORE INFORMATION

If you review the execution plan for the query, you can see the remoting of the Sub-SELECT function in the "RemoteQuery" node of the execution plan. The following query demonstrates the incorrect remoting of the query:

declare @startDate 	datetime
declare @endDate 	datetime

select @startDate = '2003-01-15'
select @startDate = '1998-06-03'

select 	orderID, customerID, employeeID 
into	tTemp
from 	[remoteServer].northwind.dbo.orders
where	customerID in ('NORTS', 'BLAUS', 'GREAL')
  and	requiredDate >= @startDate
  and	requiredDate <= @endDate
order by customerID, requiredDate

The following text is the truncated execution plan for the query:

|--Table Insert(OBJECT:([tTemp])     |--Top(ROWCOUNT est 0)          |--Sort(ORDER BY:([ryanston-lptp].[northwind].[dbo].[orders].[CustomerID] ASC...
               |--Remote Query(SOURCE:(ryanston-lptp), QUERY:(SELECT Col1019,Col1017,Col1016,Col1015 FROM (SELECT Tbl1001."OrderID" Col1015,Tbl1001."CustomerID" Col1016,Tbl1001."EmployeeID" Col1017
