  Hello

  I have a data in table (raj_table) with columns (char11) raj_id, raj_number (varchar2 (15)), raj_format (NUMBER), Primary_ID (identity with the values of the primary key column)

  Primary_ID raj_id Raj_number Raj_format

  1                            raj                 rajvend                      1

  2                            raj                 rajvend                      1

  5                            raj                 rajvendor1                 2

  6                            raj                 rajvendor2                 3

  I used under SQL to get query output as below, but has not achieved the required result:

  Select client_id vendor_number, vendor_format, primary_id, row_number() on sl_no (client_id partition, primary_id, vendor_format order of client_id primary_id, vendor_format, vendor_number, vendor_number)

  3                   6                    raj              rajvendor2                3

  I need help with a SQL query to get the result as above without using the group by clause. I want to bring together the combination of separate line of the three columns (raj_id, raj_number, raj_format) and add a unique serial number for each online game (SL_NO column below). So, above there are 3 unique set of (raj_id, raj_number, raj_format) I can get in a group by clause, but I can not add prmiary_id, SL_NO values if I group by clause. I used the analytical functions like row_number() but no luck. Need solution for this.

  Dear Bernard,

  You must use the function analytic lag to select a value from a previous line.

  Example:

  with some_days as
  (
    select
      level           as id
    , sysdate + level as the_date
    from DUAL
    connect by level < 101
  )
  select
    id
  , the_date
  , lag(the_date) over (order by id) the_previous_date
  , the_date - lag(the_date) over (order by id) difference_in_days
  from some_days
  ;

  From now when the user enters values for parameters 1 and 9, the output is written to a text file named FILE_1.txt in the folder fichier_2 for the input of 10 and 19 values and FILE_3 for all others.
  
  The new requirement is to write the output of p_low and p_high of 13 in a different file (probably in FILE_13.txt I want to add to the code). I can do simply, but when the user enters in the range of 10 and 19, which should exclude the 13 and write to FILE_2.txt.
  
  How can this be achieved other than the ref cursor?
  
  Published by: Nel Marcus Sep 19, 2011 13:23

  The case statement said if not p_low 13 and p_high is not 13 and the value of low_high_value in the "current" folder is 1 otherwise 0 13 back and back.

  So, if you spend 10 and 19 (or nothing at all, except 13 and 13) to your procedure then p_low! = 13 has the value true, p_high! = 13 will be true for all rows in the result set. For all rows in the result set where low_high_value is not 13, then the low_high_value = 13 will be false, so the case expression returns the value in the other part (1). Where low_high_value is 13, then low_high_value = 13 will be also true for the case expression returns the value of the part then (i.e. 0) so all lines except 13 will be returned.

  When you pass 13 and 13, then p_low! = 13 will be set to false if the value of the other part (1) will be returned.

  The predicate together checking if the expression box returns 1.
