  Hello

  That's what you asked for in Oracle 10:

  SELECT       a.*
  ,       CASE
             WHEN  action = 'break'
             THEN  LAST_VALUE ( CASE
                                  WHEN  action = 'fix'
                                  THEN  author
                                 END
                                 IGNORE NULLS
                             ) OVER ( PARTITION BY  id
                                             ORDER BY      tmstmp
                                  )

  FROM       actionhistory         a
  ORDER BY  id
  ,            tmstmp
  ;
  

  Like all of the built-in functions, LAST_VALUE is documented in the manual of the SQL language:

  Much more, it would help if you posted the request.
  It looks like you were using the old outer join notation (+). You can get the desired results by using an outer join with ANSI rating, but I think it would be more complicated and slower than with a LAST_VALUE.

  Concerning
  SAP

  Hello

  Your example of XML code is not correct, there is no LIST_G_ASSET element closing tag.
  But I guess that's not the real problem.

  the query always returns NULL for collumn1.

  The important thing to understand is that the paths that you declare in the COLUMNS clause are relative to the context item is past the main XQuery expression. He knows more about the rest of the document, in particular of his ancestors.
  In this case, you try to process a node whose absolute path would be

  /SA321/LIST_G_FAMILY/G_FAMILY/PARENT_FAMILY
  

  in a document which the node root is G_ASSET.

  The solution is to divide the query into two parts, the first one finds PARENT_FAMILY and the collection of G_ASSET and the second more shreds the collection G_ASSET is passed the first XMLTable in relational lines:

  SQL> SELECT x1.column1
    2       , x2.*
    3  FROM XMLTable(
    4         '/SA321/LIST_G_FAMILY/G_FAMILY'
    5         passing xmltype(bfilename('TEST_DIR','o5875854.xml'), nls_charset_id('AL32UTF8'))
    6         columns
    7           column1     VARCHAR2(50)  path 'PARENT_FAMILY'
    8         , assets      XMLType       path 'LIST_G_ASSET'
    9       ) x1
   10     , XMLTable(
   11         '/LIST_G_ASSET/G_ASSET'
   12         passing x1.assets
   13         columns
   14           column2 VARCHAR2(100) path 'ASSET_DESCR'
   15         , column3 VARCHAR2(50)  path 'EFFECTIVE_MONTH'
   16         , column4 NUMBER        path 'EFFECTIVE_YEAR'
   17         , column5 NUMBER        path 'ASSET_AMOUNT'
   18         , column6 NUMBER        path 'EXEMPT_GAIN_AMOUNT'

   22         , column10 NUMBER       path 'RATE_FROM_LAW'

• How to get unpaid balance 30 days from date selected

  Hi all
  
  I have to get the UPB (outstanding balance) of the table every day and I need to check the UPB of last month. There are daily and monthly tables separate. And according to the user enter the range of dates as the value of the setting that I need to get the monthly table.
  for example if the user enters the date range 01/08/2011 to 15/08/2011 while I check for the month of July monthly table to get the month previous UPB.
  
  Help, please
  
  Thank you

  Have you tried the add_months function?

  This would allow you to find the date of one month before the given value, then you can truncate to get the previous month. I have not tested, but I guess that the code would be something like as below:

  select trunc(add_months(to_date('15-08-2011','dd-mm-yyyy'),-1),'MON')
  from dual;
  
  01-JUL-11
  

  I don't know the layout of your tables, but I hope it helps.

  Please guys if you have any solution and I really advise thanks to you.

  Not exactly under what circumstances specific as you try to reach this goal, but suppose you have a few guest dashboard where you select a day and you have a report with a measure where you want to show the sales of the last day of the previous month based on the selected date in the dash prompt.

  If you change the formula of this measure to something like:

  FILTER (with the HELP of 'Sales' (DATE = TIMESTAMPADD (SQL_TSI_DAY-1, TIMESTAMPADD (SQL_TSI_DAY, DAYOFMONTH(@{PV_DATE_SELECTED}) * (-1) + 1, @{PV_DATE_SELECTED}))))

  Thanks in advance.

  Try the below

  SELECT LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))) lastday.

  BOX WHEN TO_CHAR (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))), 'DY') = 'SAT '.

  SO LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))-1

  WHERE TO_CHAR (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))), 'DY') = 'Sun '.

  THEN LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))-2

  Of OTHER LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))

  END as lastweekday,

  BOX WHEN TO_CHAR (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))), 'DY') IN ('Sam', 'SUN')

  THEN LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))

  Of OTHER LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))

  -(TO_NUMBER (TO_CHAR (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))),' from)) - 1).

  END as lastweekendday,

  BOX WHEN TO_CHAR (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))), 'DY') = 'MY

  THEN LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2)))

  Of OTHER NEXT_DAY (LAST_DAY (ADD_MONTHS (TRUNC(startdate,'MM'), ((LEVEL*2)-2))), "LUN")-7

  END AS lastmonday

  FROM (SELECT SYSDATE startdate,

  SYSDATE + 300 enddate

  THE DOUBLE)

  CONNECT BY LEVEL<=>

  HII
  
  I can get the week number of calendar for a given date using
  
  SELECT to_char (to_date('04/04/2011','MM/DD/YYYY'), 'WW') FROM dual

  Perhaps this...

  SQL> select trunc(sysdate,'WW')+6 from dual;
  
  TRUNC(SYSDATE,'WW')+
