Not sorting ??

SELECT  XMLAGG(

         WHERE  RN >= (((cp_pageNumber-1) * cp_pageSize) + 1)*/This is my select stmt in xml formate,
at front end application the sorting is now working.
When i am executing at backend its working, and executing in .net application its working, when i am deploying at clientside
its not sorting...??
here Databases we areusing
Oracle 10g .2 v,
.net 3.5

Answer 1

I don't think your rownum is going to work based on the order defined in a inner query
I would do this:
SELECT  XMLAGG(
                        XMLELEMENT("SCHEDULEHISTORY",
                                   XMLFOREST(SCHEDULENAME,
                                             TO_CHAR(IMPORTSTARTTIME, ''MM/DD/YYYY HH24:MI:SS.FF6'') IMPORTSTARTTIME,
                                             TO_CHAR(IMPORTENDTIME, ''MM/DD/YYYY HH24:MI:SS.FF6'') IMPORTENDTIME,
                                             TO_CHAR(READINGSSTARTTIME, ''MM/DD/YYYY HH24:MI:SS.FF6'') READINGSSTARTTIME,
                                             TO_CHAR(READINGSENDTIME, ''MM/DD/YYYY HH24:MI:SS.FF6'') READINGENDTIME,
                                             NUMOFMETERSIMPORTED, STATUS
                      ).GETCLOBVAL()
         FROM  ( SELECT SCHEDULENAME, IMPORTSTARTTIME, IMPORTENDTIME, READINGSSTARTTIME, READINGSENDTIME, NUMOFMETERSIMPORTED, STATUS, ROWNUM RN
                 FROM   (
                          SELECT rownum as row_number,SCHEDULENAME, IMPORTSTARTTIME, IMPORTENDTIME, READINGSSTARTTIME, READINGSENDTIME, NUMOFMETERSIMPORTED, STATUS
                          FROM   DATAIMPORTHISTORY ';
                          ORDER BY DECODE(cp_sortDir, 'A',
                                                             DECODE(cp_sortBy, 'SN', SCHEDULENAME,
                                                                               'IST', IMPORTSTARTTIME,
                                                                               'IET', IMPORTENDTIME,
                                                                               'RST', READINGSSTARTTIME,
                                                                               'RET', READINGSENDTIME,
                                                                               'NMI', NUMOFMETERSIMPORTED,
                                                                               SCHEDULENAME
                                      DECODE(cp_sortDir, 'D',
                                                             DECODE(cp_sortBy, 'SN', SCHEDULENAME,
                                                                               'IST', IMPORTSTARTTIME,
                                                                               'IET', IMPORTENDTIME,
                                                                               'RST', READINGSSTARTTIME,
                                                                               'RET', READINGSENDTIME,
                                                                               'NMI', NUMOFMETERSIMPORTED,
                                                                               SCHEDULENAME
                                            ) DESC
                 WHERE row_number < ((cp_pageNumber * cp_pageSize) + 1)
         WHERE  RN >= (((cp_pageNumber-1) * cp_pageSize) + 1)Assuming that your commented order by isn't working
