• Help with the query to select only one record from the result set in double

  Hello

  Please help with the query. Version of Oracle database we use is 10g R2.

  I have a vision that is duplicated IDS, but they are used across the different functions. See below examples of data. Please help me with a query to select only one record (based on ID regardless of the area) from the bottom of the result set of duplicate records. For what is the point of view is there unique records, given the combination of the fields ID, Org, DF, dry, Sub-Sec

  ID	Org	DF	Sec	Sub-Sec

  
  (163)CQCPDMCPDMHD(163)PCENGENGENG(163)CQASICASICIS8888TSTACTACTAC(163)TSHEHESW6789CQINFOINFOFOS6789PCSECSYSSECSYSINFO16789TSSECSYSSECSYSINFO29009PCBMSBMSBMS1

  My result set must eliminate the duplicate identifiers regardless of whoever we choose of the result set. (I mean without distinction Org, DF, s, Sub-s). My expected result set should be.

  ID	DSB

  
  DF
  SEC
  Sub-Sec
  (163)CQCPDMCPDMHD8888TSTACTACTAC6789CQINFOINFOFOS9009PCBMSBMSBMS1

  Hello

  This sounds like a job for ROW_NUMBER:

  WITH got_r_num AS

  (

  SELECT id, DSB, df, s, sub_sec org

  ROW_NUMBER () OVER (PARTITION BY ID.

  ORDER BY org

  ) AS r_num

  OF view_x

  )

  SELECT id, DSB, df, sub_sec s,

  OF got_r_num

  WHERE r_num = 1

  ;

  He is a Top - N query example, where you choose the elements of N (N = 1 in this case) from the top of an ordered list.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) to your sample data and the results desired from these data.  (I know that you said that you were a view selection.  Just for this thread, pretending it is a picture and post simple CREATE TABLE and INSERT statements to simulate your point of view).
  Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places.  (I didn't quite understand the explanation above.  I don't know why you want to

  ID ORG DF DRY SUB_SEC

  and is not

  1234 IS CQ ASIC, ASIC

  or

  TS 1234 IT IT SW

  or

  )
  If you change the query at all, post your modified version.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Help with the query to create hourly statistics

  Hello!

  I have an array of jobs. Each task has a start_date and a column end_date. end_date can be null if the job is still running.

  I need to create a query to display the number of jobs running for all hours during the last two weeks.

  A job can run for more than an hour.

  
  

  I tried to define what it means for a job during an interval:

  
  

  Job.Start_date < = Interval.end AND Job.Finish_date > = Interval.start

  
  

  Can help you with this query?

  
  

  Thank you!

  I tried to define what it means for a job during an interval:

  Job.Start_date <= interval.end="" and="" job.finish_date="">= Interval.start...

  You gave essentially the solution yourself.  You just need to outside join your jobs table to a table (or, in the example below, a result set that acts like a table) containing 1 row for each interval.  You can use NVL to equate finish_dates with an effective DATE NULL, so they will be counted:

  WITH intervals AS

  (

  SELECT TRUNC (SYSDATE, 'HH') - ((LEVEL-1)/24) AS interval_start

  , TRUNC (SYSDATE, 'HH') - ((LEVEL-2)/24) AS interval_end

  OF the double

  CONNECT BY LEVEL<= 14="" *="">

  )

  SELECT i.interval_start

  EARL of (j.start_date) AS jobs_running

  Intervals I have

  LEFT OUTER JOIN jobs j WE j.start_date<=>

  AND NVL (j.finish_date

  i.interval_end

  ) > = i.interval_start

  ;

  If you would care to post a small example of data (CREATE TABLE and INSERT statements) and the results desired from this data, I was able to test this.

  Simplify the problem for display.  Do what you are interested only for the past 6 hours, not the last 2 weeks.  We will find a solution that can easily adapt to any number or intervals.

• Help with the query

  Hi, can someone help me with the query. I try to display comm based on calculation below

  SAL < 5000 then 10%

  This is the query

  Hello

  Look at the syntax of the IF in the PL/SQL manual.  Comapre to the instruction BOX and also the expression BOX.

  Perhaps, instead of an IF statement

  v_comm: = (IF v_sal<5000 then="">

  ELSIF v_sal between 5001 AND 10000 THEN v_sal*.15;

  ELSE v_sal > 10001 THEN v_sal*.20;

  END IF ;);

  you wanted to write an expression BOX, like this:

  v_comm: = BOX

  WHEN v_sal< 5000                ="" then="" v_sal="" *="">

  WHEN v_sal BETWEEN 5001 AND 10000 THEN v_sal *.15

  WHEN v_sal > 10001 THEN v_sal *.20

  END;

  Or perhaps cela:

  v_comm: = v_sal * CASE

  WHEN v_sal<=  5000="" then="">

  WHEN v_sal<= 10000="" then="">

  OF AUTRE.20

  END;

  You can also use a CASE expression in the SELECT statement.

• Help with the query to return the last possible value

  Can someone please help me to create a query for the situation below?
  
  Table: TABLEA
  Columns:
  FACID VARCHAR2 (10),
  DEPTID VARCHAR2 (10),
  CHARGENUMBER NUMBER (10)
  
  I have the following data:
  
  A, B, 1
  A, B, 2
  C, D, 3
  C, D, 4
  
  I will return the following:
  
  A, B, 2
  C, D, 4
  
  In other words, I would return the last possible CHARGENUMBER for FACID and DEPTID.
  The table has no index, and it is responsible for a worksheet in that order.
  
  Thank you very much!

  Hello

  If you have a TIMESTAMP column, called entry_dt, you can use a Top - N query like this to find the last x entries.

  WITH  got_rnum  AS
  (
       SELECT  my_table.*
       ,     RANK () OVER (ORDER BY entry_dt DESC)     AS rnum
       FROM     my_table
  )
  SELECT     *     -- or list all columns except rnum
  FROM     got_rnum
  WHERE     rnum     <= x
  ;
  

  It is very common to have a trigger to ensure that columns like entry_dt are met.

  If you have only one statement that inserts with hundreds of lines, they can all have the same entry_dt. (The value of SYSTIMESTAMP is constant throughout a statement, even if it takes a few seconds).
  The above query uses RANK, so if you tell him you want the last 10 entries, it can return more than 10, because it includes all lines with exactly the same entry_dt as the 10th. If you want to exactly 10 rows returned, even if there is a tie for 10th place, then use ROW_NUMBER instead of RANK; the rest of the query is the same.

• Help create the query

  Hi all
  
  I have the below requirement.

  Master table:

  1               TV
  2               Cellphone
  3               Laptop
  4               DVD Player

  4               Color          Blue
  4               Weight          20
  4               Height          10

  I'm looking for a way to identify products with the exact same specifications.
  
  That is to say, in the example TV and cell phone above has exact specifications.
  So the result of the query must be TV and phone cell phone here.
  
  Is it possible to do in a query, or we need a sql block to perform this action.
  
  Any help would be greatly appreciated.

  But why devil you or your specifications product model predecessor like that? You are much more complicated that it should be. And the data type of size and weight should be not the same as those of color. But now they are. And how do limit you the allowed values for the colors? Color, weight and size are characteristic of your products so that they should have been modeled like this.

  See how easily your questions becomes after remodeling it:

  You could be in one of the rare cases where the index should be rebuild, take a look in the following thread:
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6601312252730 #69571308712887 (search for 'index of Sweeper')
  Make sure that you have checked if you are in this case before going for an expensive index rebuild.

  This will give you an idea of what I'm trying to do:

  Thanks for your help!

  Hello

  Welcome to the forum!

  You were on the right track. To find if a given subscriber corresponds to any prefix_code, you can do an EXISTS subquery:

  SELECT     subscriber_id
  FROM     subsribers     s
  WHERE     EXISTS ( SELECT  NULL
                    FROM      prefix_codes
             WHERE      s.subscriber_id     LIKE prefix_code || '%'
              )
  ;
  

  This will tell you if at least a prefix code. It won't tell you exactly how many, or what they were.
  Your message, I'm guessing that there may be more than one, and you can deduct the subscriber_id itself, then the above query should work for you.

  WITH got_distinct_jobs AS

  (

  SELECT DISTINCT deptno, job

  SELECT job_list

  COUNT (*) AS num_departments

  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.

  WITH     got_family_cnt     AS
  (
       SELECT     family_code
       ,     wers_feature_code

  FROM     got_family_cnt
  WHERE     LEVEL     = family_cnt
  CONNECT BY NOCYCLE     family_code     != PRIOR family_code
  ;
  

  It produces 48 lines
  (2 choices for family 'AAA'
  * 2 for "BBB".
  * 2 for "CCC".
  * 3 choices for 1 family
  * 2 (2nd).

  This assumes you know some substring that never happens in wers_feature_code. I used ' > ' above, but you can use anything else.

• Help with the query to return the results of the group in the table?

  Hello
  Im a total noob, so please be nice...!
  
  I'm looking around a table contains a column of WORD and a WORD_TYPE_ID column.
  Words can have the same type_id.
  
  What I'm trying to do is to write a query that will return the longest word for each word_type_id.
  I tried for hours to get it and everything seems to get is two error messages or just the longest word in the whole WORD column.
  
  Is the furthest I can get before things break down...
  
  Select Word
  table
  where
  Length (Word) =
  (
  Select
  Max (length (Word))
  table
  )
  
  Any help on this or if I could be pointed in the right direction it would be greatly appreciated.
  
  Thank you

  Hello

  Welcome to the forum!

  Here's one way:

  SELECT    word_type_id
  ,       MIN (word) KEEP (DENSE_RANK LAST ORDDER BY LENGTH (word))     AS longest_word
  FROM       table_x
  GROUP BY  word_type_id;
  

  If there be a tie in some word_type_id (i.e. 2 or more words have exactly the same length, which is the longest in this group) the expression above will return the first one alphabetically. (This is what means here MIN.)

  Published by: Frank Kulash, 11 August 2009 13:56

  You almost had it.
  As you have noticed, you get the longest line across the table. This is because your subquery was watching the entire table.
  If you to correlate the subquery to the row in the main table, as shown below, you can get the longest word in each group:

  select  word
  from     table     m                              -- m for main
  where      length (word) = (
                              select  max (length(word))
                 from     table
                 where     word_type_id  = m.word_type_id     -- New
                 );

  20 11-A1

  ?  You would be satisfied to one or the other?

  Depending on your answer, you may need to modify the analytical ORDER BY clause in the ROW_NUMBER function.
