Hi,
This works fine
SELECT DISTINCT SED.MCSED_SED_Short_Description, SCH.Doc_SNo,
 FROM @Schedule_Status SCH  , DMS_M_Company_Schedule_Element_Details SED
 WHERE SED.MCSED_SED_Code =123
 ORDER BY   SED.MCSED_SED_Short_Description, SCH.Doc_SNo, SCH.Doc_No


But when i introduce case expression in order by clause it shows the error
SELECT DISTINCT SED.MCSED_SED_Short_Description, SCH.Doc_SNo,
 FROM @Schedule_Status SCH  , DMS_M_Company_Schedule_Element_Details SED
 WHERE SED.MCSED_SED_Code =123
 ORDER BY   CASE SED.MCSED_SED_Short_Description WHEN 'VD' THEN 1 ELSE 2 END,
                   SCH.Doc_SNo, SCH.Doc_No


it shows the error "ORDER BY items must appear in the select list if SELECT DISTINCT is specified."
