STATUS

MORE INFORMATION

Because the problem is encountered during query normalization, attempts to view the SHOWPLAN of the query lead to the exception condition as well.

An example of a query that leads to the problem condition follows. It generally requires 2 or more tables resulting in a correlation or grouping evaluation as shown.
SELECT DestinationPage.NetworkId 
FROM DailyTQSContextUsage_20001103, 
     DestinationPage, 
     Geography  
WHERE   DESTINATIONPAGE.PAGEID = 
             DAILYTQSCONTEXTUSAGE_20001103.TARGETPAGEID 
     AND                        
        Geography.CountryId =
             DAILYTQSCONTEXTUSAGE_20001103.COUNTRYID
