  Hello
  
  This function returns me if I pass "ABC01" it returns "ABC02" as if I spend
  
  "ABC55" it returns "ABC56".
  
  But my requirment is that I need to pass the value from 01 to 99.
  so, if I'm going 'ABC99' it back South "ABC01'.
  
  If the sequence is from 01 to 99 and after 99 he will still leave the 01.
  
  create or replace function get_next_value

  Hello

  You want a way to confirm that what looks like two rows is really a line?

  Here are three ways:

  (1) count the lines:

  WITH  my_original_querry     AS
  (
       select  a.customer_trx_id || CHR(13)
                        || a.previous_customer_trx_id     as id
       from      ra_customer_trx_all     a
       where      a.customer_trx_id      = 274881
  )
  SELECT     COUNT (*)
  FROM     my_original_query;
  

  (2) in SQL * Plus, have SQL * more count them for you:

  SET     FEEDBACK     1
  
  select  a.customer_trx_id || CHR(13)
                   || a.previous_customer_trx_id     as id
  from      ra_customer_trx_all     a
  where      a.customer_trx_id      = 274881;
  

  (3) implicitly count them with the ROWNUM Pseudo-column

  select  a.customer_trx_id || CHR(13)
                   || a.previous_customer_trx_id     as id
  ,     ROWNUM
  from      ra_customer_trx_all     a
  where      a.customer_trx_id      = 274881;

• Not able to understand the query logic

  Hello
  
  Please, help me to understand the logic of the query below.

  Query giving no line.
  
  I need to know the logic of the query.
  
  Thank you
  HIMS

  Because there are some NULL values in the column so 'IN' mgr_id would fail to compare values such as 1,4,8,9 which are not there in mgr_id with these NULL values.

  Use NVL like below to get the desired results...

   
  
  with t as
  ( select 1 emp_id,  null mgr_id from dual union all
    select 2,2 from dual union all
    select 3,3 from dual union all
    select 4,5 from dual union all
    select 5,null  from dual union all
    select 6,5  from dual union all
    select 7,6  from dual union all
    select 8,6  from dual union all
    select 9,7  from dual
  )
  SELECT *
    FROM t
   WHERE emp_id NOT IN (SELECT nvl(mgr_id,0) from t );

• I need to stop a download of the query, I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not who have, or want to buy.

  I need to stop a download of the query, that I thought a stand-alone application but turns require a higher level (FCPX) as a 'parent' and I do not have that, or I want to buy it.

  Motion IS a stand-alone application. It is mainly designed to make effects for Final Cut Pro X, but it is not necessary to have with FCPX nor is it necessary to have FCPX to create projects for other purposes. When you open the query, simply select project of work outside the FCPX motion. You can save regular projects of Motion anywhere on your system.

  Hi gurus

  I was reading one of the question here in this forum and its link is below:

  Query required for scenario

  I had some confusion related to this code and don't understand the logic of the out put, see query below:

  Query

  with sub_services as

  Select *.

  of sub_services b

  where exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  )

  order by 2;

  The query result

  12323 A09 3

  12333 6 A09

  12323 HLR1 1

  12323 HLR2 2

  12333 M0CR 7

  12333 4 MO1

  12333 5 MO2

  According to my understanding, the above query should return records in red only because of her is below command

  It exists (select 1 from sub_services

  where su_seq = b.su_seq

  and so_id = 'A09.

  but don't know why he's back 7 files, can someone help me understand the result...

  It is query is functionally identical to the PL/SQL block, but much more effective.

  declare

  number of l_res;

  Start

  for line (select *)

  sub_services) loop

  Start

  Select 1 from l_res

  of sub_services

  where su_seq = row.su_seq and

  so_id = "A09" and

  rownum = 1;

  exception when

  NO_DATA_FOUND then

  null;

  end;

  end loop;

  end;

  Essentially every row in the outer query are tested against him exists query.  Given the correlation between two requests is based only on su_seq each line with a su_seq value returned by him is returned in the output.

  Another way to think he uses instead a join condition.  This query is equivalent to the query to exist

  Select the main

  of main sub_services

  Join select (separate su_seq

  of sub_services

  where so_id = "A09") cond

  We main.su_seq = cond.su_seq;

  Hello

  Here is another way, it is easier to adapt to different jobs and different numbers of jobs:

  WITH got_distinct_jobs AS

  (

  SELECT DISTINCT deptno, job

  FROM scott.emp

  WHERE job IN ("ANALYST", "CLERKS") - or what

  )

  got_job_list AS

  (

  SELECT LISTAGG (job, ",") THE Group (ORDER BY work) AS job_list

  OF got_distinct_jobs

  GROUP BY deptno

  )

  SELECT job_list

  COUNT (*) AS num_departments

  OF got_job_list

  GROUP BY job_list

  ;

  This shows all the combinations of the jobs listed in the WHERE clause of got_distinct_jobs.  You don't need to change anything else in the query.  There may be any number of jobs.

  Output:

  JOB_LIST NUM_DEPARTMENTS

• Need help to highlight the query text in the document

  Hi, I'm trying to load files into the blob column and try to create the text index.
  
  I need to query the blob column in the original glass by a string, which should return the relevant documents with the query string, highlighted with some color.
  
  Can you please help me with an example of the above.

• Need help in the optimization of the query with the Group and joins by clause

  I'm having the problem by running the following query... It takes a lot of time. To simplify, I added the two tables FILE_STATUS = stores the file load details and COMM table Board table job showing records treated successfully and which was communicated to the other system real. Records with status = T is trasnmitted to another system and traansactions with P is waiting.

  CREATE TABLE FILE_STATUS
  (FILE_ID VARCHAR2(14),
  FILE_NAME VARCHAR2(20),
  CARR_CD VARCHAR2(5),
  TOT_REC NUMBER,
  TOT_SUCC NUMBER);
  
  CREATE TABLE COMM
  (SRC_FILE_ID VARCHAR2(14),
  REC_ID NUMBER,
  STATUS CHAR(1));
  
  INSERT INTO FILE_STATUS VALUES ('12345678', 'CM_LIBM.TXT', 'LIBM', 5, 4);
  INSERT INTO FILE_STATUS VALUES ('12345679', 'CM_HIPNT.TXT', 'HIPNT', 4, 0);
  
  INSERT INTO COMM VALUES ('12345678', 1, 'T');
  INSERT INTO COMM VALUES ('12345678', 3, 'T');
  INSERT INTO COMM VALUES ('12345678', 4, 'P');
  INSERT INTO COMM VALUES ('12345678', 5, 'P');
  COMMIT;

  Here's the query I wrote to give me the details of the file that has been loaded into the system. He reads the table of State and the commission files to display the name of the file, total records loaded, total at the table of the commission and the number of records which has finally been passed successfully loaded (Status = T) with other systems.
  

  SELECT 
      FS.CARR_CD 
      ,FS.FILE_NAME 
      ,FS.FILE_ID
      ,FS.TOT_REC
      ,FS.TOT_SUCC
      ,NVL(C.TOT_TRANS, 0) TOT_TRANS
  FROM FILE_STATUS FS
  LEFT JOIN
  (
      SELECT SRC_FILE_ID, COUNT(*) TOT_TRANS
      FROM COMM
      WHERE STATUS = 'T'
      GROUP BY SRC_FILE_ID
  ) C ON C.SRC_FILE_ID = FS.FILE_ID
  WHERE FILE_ID = '12345678';

  In production, this request has several joins and takes a long time to deal with... the main culprit for me is the join on the COMM table to count the number of number of transactions sent. Please can you give me tips to optimize this query to get results faster? What I need to delete the Group and use the partition or something else. Help, please!

  Don't know if it will be faster based on the information provided, but analytical functions offer an alternative approach;

  select carr_cd, file_name, file_id, tot_rec, tot_succ, tot_trans
    from (select fs.carr_cd,
                 fs.file_name,
                 fs.file_id,
                 fs.tot_rec,
                 fs.tot_succ,
                 count(case
                          when c.status = 'T' then
                           1
                          else
                           null
                        end) over(partition by c.src_file_id) tot_trans,
                 row_number() over(partition by c.src_file_id order by null) rn
            from file_status fs
            left join comm c
              on c.src_file_id = fs.file_id
           where file_id = '12345678')
   where rn = 1;
  
  CARR_CD FILE_NAME            FILE_ID           TOT_REC   TOT_SUCC  TOT_TRANS

• Extend the VO - need to change the query of VO - screen is off

  {Re-post the message in this forum (thanks to John Stegeman to lead me here...)   {Posted: August 28, 2009 04:27}
  
  Dear all,
  
  Thanks to this great body of knowledge, I ask my questions.
  
  I need to extend a VO to display the name of the country.
  The column is not in the VO. So, I need to get another table: FndTerritories
  
  I want to change the query, but the request frame is turned off (in the wizard the View - step 5 of 6 - Generated statement object substitution)
  
  Could you be it someone please let me know: how to change the application of the VO in this case?
  
  OR is there another solution for such cases, to maintain development standards
  
  Thank you very much
  
  Kind regards

  Hello

  I think that's when you just have to add an attribute, you should not click the expert mode checkbox... make use of
  Mix and add the button.

  But when you need to modify the query, and then we want to use to modify the query window...

  Thank you
  Gerard
