• find the closest value in table

  Hi all

  I need to find the values in the "C" line which is equal or close to the values 'A' in the 2D array, and then I want to show the values of 'B', corresponding to the values of 'C' in table 2D.

  How can I fix it?

  Thank you!

  

  0.9967 nearest value is 0.993807 in the 8 Cand in row B row, not 1. The differences are 2.893E - 3 and 3.300E - 3.

  Subtract each value from the table C. take the absolute value of the difference. To find the index of at least using Max & Min value of B. Using autoindexing array Index, create the output array.

• How to find the closest higher value?

  Hi all
  
  I want to select the closest higher value in my data (test data are below):
  

  with test_data as
  ( select 0.21 as val1, 0.19 as val2 from dual
    union all
    select 0.21 as val1, 0.29 as val2 from dual
    union all
    select 0.21 as val1, 0.49 as val2 from dual
    union all
    select 0.67 as val1, 0.49 as val2 from dual
    union all
    select 0.67 as val1, 0.69 as val2 from dual
  )
  select * from 
  (
  select 
  val1,
  val2,
  rank() over (order by abs(val2 - val1)) nearest
  from test_data
  )
  where nearest = 1;

  output:

  VAL1    VAL2    NEAREST
  0.21     0.19     1
  0.67     0.69     1

  Output of this query is the NEAREST value to the value in the column of VAL1. But I would get the SUPERIOR value CLOSEST. As below the value at the higher value 0.21 closest isn't 0.29 0.19.
  
  desired output:

  VAL1    VAL2
  0.21     0.29
  0.67     0.69

  Is it possible to get the features you want using analytical functions?
  
  Thx for the help!
  
  Kind regards

• How to find the max value of scrollV in AS3?

  I used the response from Ned to get my 3 fields of scrolling text set based on the value of one of them. Thanks Ned!

  The other two text fields scroll to match the text box 'parent', but in the end – you get to the last scroll position - the other two do not update and 3 text fields are out of alignment. It's just at the end of the roll. The rest of the scroll values line up. I think that if I can find the scrollV max value, I can force the two others to scroll one last time when this value is reached by the text field "parent".

  The textfield object has a property for this: maxScrollV.

• How to find the date of a table Max

  Hello world
  
  I have two tables in the database. I want to find the maximum routine for a case_id of the lock_date date between jan 20 to January 29, 2012.
  
  But I don't get real output (output routine_date should be 'January 28, 2012' but I m getting "January 31, 2012" ")

  Select m.case_id, r.routine_date from master m, systematic r,

  and r.routine_date = rr.routine_date

  Hello

  Here are average dradles:

  WITH     universe  AS
  (
       SELECT    m.case_id
       ,        r.routine_date
       ,       MAX (r.routine_date)     OVER (PARTITION BY  m.case_id)
                       AS max_routine_date
       FROM       master       m
       ,        routine       r
       WHERE        m.case_id       = r.case_id
       AND       m.lock_date       >= TO_DATE ('20-Jan-2012', 'DD-Mon-YYYY')
       AND       m.lock_date       <  TO_DATE ('30-Jan-2012', 'DD-Mon-YYYY')
  )
  SELECT       case_id
  ,       routine_date
  FROM       universe
  WHERE       routine_date     = max_routine_date
  ;
  

  You only want to view rowss whose routine_date is the maximum date in a subset. First get this subset
  If the universe of data that you are interested in is just the period from January 20 to January 29, then you can start by getting all the data in this range. This is what the above subquery universe.
  Now, you want to see only the rows where routine_date is the max_routine_date within this universe, for each case_id. You can use the analytic MAX function to find out what this max_routine_date.

• How to compare the 3 values in table

  Hi all

  This is my first post so be tolerant

  I need to find "bad values" in the table, it will be easier to explain with example:

  I have a table like this: 0 0 0 0 0 0 0 0 5 0 0 0 0<- so="" "5"="" is="" the="" bad="" value,="" my="" method="" is="" to="" check="" two="" of="" nearby="" values="" so="" x(i-1)="0," x(i)="5" x(i+1)="0," and="" if="" checked="" value="" is="" more="" than="" 25%="" bigger="" or="" smaller="" it="" should="" be="" replaced="" by="" average="" of="">

  example: 0 1 2 3 4 9 6 7 8<- bad="" value="" is="" 9,="" and="" result="" of="" my="" filter="" should="" be="" (4+6)/2="">

  I did it using the formula node (not 20% and no way, but the point is the same) and it works but now I want to do without C and I had a lot of problems because of the size of the array memory is 10000.

  I joined thah vi and signal, you can test that it works very well

  Thank you

  ... What is the problem?

  Because the first incorrect value is the point of 2780, because it is also disabled because the average of neighbour is biased by the incorrect value to 2781.

  You could jut blindly replace all values with the value that has the lowest absolute value among the three points that we have. Here's a quick project, seems pretty good, but it really depends what you want.

• How to find the size of a table with CLOB

  Hello

  I have a table with CLOB as follows:

  SQL > desc INFO_MESSAGES

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  CLNT_OID NOT NULL VARCHAR2 (16)

  USR_OID NOT NULL VARCHAR2 (16)

  LAST_client_msg_ID VARCHAR2 (36)

  LAST_client_msg_DATE DATE

  LAST_client_msg CLOB

  LAST_USR_MSG_BOD_ID VARCHAR2 (36)

  DATE OF LAST_USR_MSG_DATE

  CLOB LAST_USR_MSG

  Now I just want to find out what is the size/area total absorbed by the table (including the CLOB columns), so how can I find? I think that the usual command does not - the

  Select format from dba_segments where nom_segment = "INFO_MESSAGES" is only showing 7 MB, while I think that the table has several GB of space due to the CLOB.

  Also to add one more detail: when dba_segments seeking, I see a result like this:

  Select * of dba_segments order by bytes DESC;

  MIGRTN SYS_LOB0000111131C00008$ $ LOBSEGMENT SAMS DATA1 20690 6 1963 14528000 119013376000 <-the top row

  MIGRTN this is the schema where this INFO_MESSAGES table is present.

  Thanks,

  OrauserN

  you will need to add the segment_size of the LOB segments to the segment_size of the table. The connection between the two pieces of information you find in USER_LOBS (or the corresponding ALL_, DBA_ objects).
