Hi All,
I am facing a filter data issue,to avoid duplicates query.

SELECT
ErrorList.ErrorMessage
,ErrorList.FilePath
,ErrorList.ErrorStatus
,ErrorList.Browser
,ErrorList.Referer
FROM ErrorList inner join
(SELECT MAX(errorlistid)AS id
FROM errorlist
GROUP BY ErrorMessage,filepath,ErrorStatus)DistinctSet
ON ErrorList.errorlistid=DistinctSet.id
ORDER BY ErrorList.ErrorMessage

query is working fine.

The above query gives a list of records that are distinct based on ErrorMessage,filepath,ErrorStatus.

But my problem is that, still the recordset is not distinct based on error message column.
i will show the sample example to argue my point

ErrorMessage column
[Macromedia][SQLServer JDBC Driver][SQLServer]Transaction (Process ID 116) was deadlocked. The error occurred on line 447.
[Macromedia][SQLServer JDBC Driver][SQLServer]Transaction (Process ID 117) was deadlocked. The error occurred on line 447.

so there process id is different, so it came as in the result set as two distinct records.
So my issue is tat can we avoid (Process ID 116) text from tat column at the time of group by process..
Is it possible...
If tat is possible i have another condition is tat (Process ID 116) may or may not come as text in tat column.

Thanks in advance..

try this out:-

SELECT
ErrorList.ErrorMessage 
,ErrorList.FilePath 
,ErrorList.ErrorStatus 
,ErrorList.Browser 
,ErrorList.Referer 
FROM ErrorList inner join
(SELECT MAX(errorlistid)AS id
FROM errorlist 
GROUP BY STUFF(ErrorMessage,CHARINDEX('(',ErrorMessage),(CHARINDEX(')',ErrorMessage)-CHARINDEX('(',ErrorMessage))+1,'')
,filepath,ErrorStatus)DistinctSet
ON ErrorList.errorlistid=DistinctSet.id
ORDER BY ErrorList.ErrorMessage
