SELECT ROW_NUMBER() OVER (ORDER BY UserInOut.mnmUser,UserInOut.DtTime)AS RowNUm,CAST(UserInOut.DtTime AS DATE)AS DtDate,
UserInOut.mnmUserAccessType as Access_Type,'IND' AS Access_Country,
CASE WHEN CHARINDEX(',',UserInOut.mnmIPDetails,1) > 0 THEN reverse(left(reverse(UserInOut.mnmIPDetails), charindex(',', reverse(UserInOut.mnmIPDetails)) -1))ELSE UserInOut.mnmIPDetails END as Access_SourceIP 'NULL' as Access_SourceHost,InOut,UserInOut.mnmUser,UserInOut.DtTime from dbo.UserInOut INNER JOIN dbo.DealerAddMrv where UserInOut.DtTime >= @ANHOURBACK

WHERE mnmIPDetails IS NOT NULL?

Please keep in mind the people you are talking have no knowledge of your
table or business problem? If my out-of-the blue guess does not answer
your question, my advice is that you post 2) CREATE TABLE statements for
your table(s), 2) INSERT statements with sample data, enough to illustrate
all angles of the problem. 3) The expected result given the sample data. 4)
A short description of the business rules why you want result, 5) The output
from "SELECT @@version" so that we know which version of SQL Server you are
using.
