  Hi I am new to oracle analytical functions

  I do not know how to use and where to use real-time, please send me the useful any url for it.

  I read in the Oracle Documentation , but it's not understand for me.

  Please provide me with any other useful URL, I'll read to those.if you have examples, please report it in the present.

• Analytical function in Oracle

  I have a situation where I partitioned a Recordset. If in one partition on this recordset, the value of a field (field name registered) is '45' I need to order the result of this partition by - "outdate" desc "this provision" desc and order the other partition of desc 'key',' sequence ' desc, desc "outdate."
  
  If the query looks like to.
  
  Select row_number() over (partition by the order of the keys in sequence) RowNo, key, seq, status, outdate, receivedate from table1 where...
  order by?
  
  
  RowNo status outdate Seq key provision
  1 200 0 24 9/13 / 2009 12/9/2009
  2 200 1 23 9/10 / 2009 9/09/2009
  3 200 2 24 9/09 / 2009 9/08/2009
  
  1 210 0 24 9/13 / 2009 12/9/2009
  2 210 1 * 45 * 9/09/2009-9/08/2009
  3 210 2 24 9/10 / 2009 9/09/2009
  
  So I need to get the query that will order the first series of partition by desc 'key',' order ' desc, desc "outdate" and the second set of partition (because the status of '45' exists in the second partition) by "outdate" desc "this provision" desc.
  
  The output of the query should look like
  
  RowNo status outdate Seq key provision
  1 200 0 24 9/13 / 2009 12/9/2009
  2 200 1 23 9/10 / 2009 9/09/2009
  3 200 2 24 9/09 / 2009 9/08/2009
  
  1 210 0 24 9/13 / 2009 12/9/2009
  2 210 2 24 9/10 / 2009 9/09/2009
  3 210 1 * 45 * 9/09/2009-9/08/2009
  
  I don't know if this is possible using the analytical function.
  
  I would appreciate if any can help me with that.
  
  Thanks in advance

  Hello

  Welcome to the forum!

  You can use analytical functions in the ORDER BY clause.

  I do not have your tables, so I'll use scott.emp to illustrate.

  The following query sorts first by deptno. After this, the sort order for the departments that contain at least one seller is:
  b job
  (b) ename
  DEPTNO = 30 is be the only Department with a seller, so it's the only sorting as shown above.
  Other departments will be sorted by
  (a) sal
  (b) job

  SELECT       deptno
  ,       ename
  ,       job
  ,       sal
  FROM       scott.emp
  ORDER BY  deptno
  ,            CASE
            WHEN  COUNT ( CASE
                                 WHEN  job = 'SALESMAN'
                        THEN  1
                       END
                     ) OVER (PARTITION BY deptno) > 0
            THEN  ROW_NUMBER () OVER ( PARTITION BY  deptno
                                        ORDER BY        job
                              ,            ename
                            )
            ELSE  ROW_NUMBER () OVER ( PARTITION BY  deptno
                                        ORDER BY        sal
                              ,            job
                            )
         END
  ;
  

  Output:

  .   DEPTNO ENAME      JOB              SAL
  ---------- ---------- --------- ----------
          10 MILLER     CLERK           1300

  The small set of sample data you posted, the results you want can be achieved simply through

  ORDER BY  key
  ,         outdate     DESC
  

  I guess it's just a coincidence.

  If you need help, post some examples of data that requires really looking at the status column to get good results. Display the data in executable form, such as CREATE TABLE and the instructions INSERT, olr, as Salim, a WITH clause. (Maybe you can simply add or change a couple of lines in the example Salim already posted data).

  With your version of Oracle and high-volumes of data through the analytical function, it is likely that this blog note applies. You may need a patch upgrade or special. http://jonathanlewis.WordPress.com/2009/09/07/analytic-agony/

• Cannot use analytical functions such as lag/lead in odi components 12 c except in the expression

  Hi I am a beginner of ODI 12 c

  I'm trying to get the last two comments made on the product for a given product id. and load them into a target.

  I have a source table something like

  Product SR_NO comments LAST_UPDATED_TS

  1 good car 2015/05/15 08:30:25

  1 car average 2015/05/15 10:30:25

  Jeep 2 super 2015/05/15 11:30:25

  1 car bad 2015/05/15 11:30:25

  Jeep 2 horrible 2015/05/15 09:30:25

  Jeep 2 excellent 2015/05/15 12:30:25

  
  

  I want a target table based on their last timestamp updated as (last two comments)

  
  

  SR_NO Comment1 Comment2

  1                             bad                      average
  

  2 super excellent

  I used the logic below to get records in SQL Developer but in ODI 12 c, I'm not able to do this by mapping a source to the target table by applying analytical functions to the columns in the target table. Can someone help me solve this problem

  SELECT * FROM)

  SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

  ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

  FROM Source_table

  ) M

  WHERE RN = 1

  ;

  UM, I'm afraid that ODI puts the filter too early in the request, if it generates:

  SELECT * FROM)

  SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

  ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

  FROM Source_table

  WHERE RN = 1

  ) M

  ;

  Instead of:

  SELECT * FROM)

  SELECT SR_NO Comment1, LAG(Comment1,1,) ON Comment2 (SR_NO ORDER BY LAST_UPDATED_TS ASC PARTITION),

  ROW_NUMBER() ON RN (SCORE FROM SR_NO ORDER BY LAST_UPDATED_TS DESC)

  FROM Source_table

  ) M

  WHERE RN = 1

  ;

  Even by changing the 'run on Hint"of your component of the expression to get there on the source, the request will stay the same.

  I think the easiest solution for you is to put everything before the filter in a reusable mapping with a signature of output. Then drag this reusable in your mapping as the new source and check the box "subselect enabled."

  Your final mapping should look like this:

  

  It will be useful.

  Hello

  Here is an example of when you can use the FIRST analytic function.

  Say you want the average sal for each Department, but only for the first year (taken from the hiredate column) in the Department (i.e., the column called f in the query below).

  WITH got_hireyear AS

  (

  SELECT deptno and ename, sal, hiredate

  EXTRACT (YEAR FROM hiredate) AS hireyear

  FROM scott.emp

  )

  SELECT deptno, hireyear, hiredate, ename, sal

  AVG (sal) DUNGEON (DENSE_RANK FIRST ORDER BY hireyear)

  COURSES (PARTITION BY deptno

  ) In the FORM f

  FIRST_VALUE (sal) over (PARTITION BY deptno

  ORDER BY hireyear

  ) AS fv

  AVG (sal) over (PARTITION BY deptno

  hireyear

  ), A

  OF got_hireyear

  ORDER BY deptno

  hireyear

  ename

  ;

  The analytical FIRST_VALUE function can do (except in the very special case where only 1 row has the lowest hireyear, as in deptno = 20).  AVG analysis can do (except in the very special case that all lines have the same hireyear as in deptno = 30).

• Which analytical function to use?

  
  Hi gurus,

  DB - Oracle 11 g 2

  I followed the examples of data in the table test_a.

  col1 col2 col3

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

  x                 y                   y

  p                 q                  y

  a                b                   y

  p                q                   y

  t                 r                    y

  p                q                   y

  The col3 column is always 'y '. But here's the data p, q, there is repeated 3 times (duplicate) and if this is the case I want to update only the first recordings like "n" col3 it is to say p, q, n. rest will be as it is.

  I am able to get the row_number() for it but not able to do this.

  Select col1, clo2, clo3 row_number() over (partition by col2) arrested by col1 as test_a r_num

  Would it be possible directly by any analytic function?

  Thank you

  COL4 is logical...

  Something like that?

  with x as)

  Select col1, col2 ' x' 'y', 'y' col3 col4 1 Union double all the

  Select 'p' col1, col2 'q', 'y' col3 col4 2 Union double all the

  Select 'a' col1, col2 'b', 'y' col3 col4 3 of all the double union

  Select 'p' col1, col2 'q', 'y' col3 col4 4 Union double all the

  Select 't' col1, col2 'r', 'y' col3, col4 5 Union double all the

  Select 'p' col1, col2 'q', 'y' col3 col4 6 double

  )

  ---

  Select * from)

  Select x.*,

  ROW_NUMBER() on rn1 (score of col1, col2, col3 col4 sort),

  ROW_NUMBER() on rn2 (partition by col1, col2, col3 col4 desc sorting)

  x

  )

  where rn1 = 1 and rn2 <> 1;

  Understand the logic and simply change SELECT a query to UPDATE...

  Analytical functions, such as the COUNTY and MIN, many global versions, in addition, it can give the same results.  Use the analytical versions when each row of output corresponds to exactly 1 row of input and the aggregate and GROUP BY version when each line of output corresponds to a group of lines 1 or more input.  In this issue, each line of output appears to be a group of input lines having the same group_id, part_type_id, and part_desc_id (I'm guessing just, this only has never stated), so I used GROUP BY to get 1 row of output for every input lines.

  Normally, your developers are older than your software.

  You should be able to do what you want with a self-join on t2; a copy (d) should be displayed, and the other copy (c) contains all related values you need for comparison.

  SELECT t2d.id

  I've tested this in Oracle 11, but it should work in Oracle 7.

  I have a doubt about this analytical function to lead,

  I have this table,

  create table test3 (no number, name varchar2 (30));

  
  Insert into TEST3 (NO, NAME) values (1, 'fen');
  Insert into TEST3 (NO, NAME) Values (3, 'DEN');
  Insert into TEST3 (NO, NAME) values (2, 'Sun');
  Insert into TEST3 (NO, NAME) values (2, 'sen');
  Insert into TEST3 (NO, NAME) values (1, 'end');
  COMMIT;

  I put like that with this request.

  
  Select lead don't (don't) over (partition by any order of name), name of test3.

  NO NAME

  1 fen
  end
  2 Sun
  Sen
  DEN

  But I need as below output, I am unable to get the third 'NO' that has a value, I get null for that, even if I partitioned
  by the 'NO '.

  NO NAME

  1 fen
  end
  2 Sun
  Sen
  3 DEN

  Please clear my doubt.

  Thanks in advance.

  Like this

  Select decode (NWR, 1, no, null) no

  name

  de)

  Select row_number() over (partition by any order by name) rno

  None

  name

  of test3

  )

• Analytical function?

  Hello

  I have two tables b rates and transactions (b).

  For each b.FS, I want to know new amount (b.amt time a.rate to the corresponding line of FS b and if a.na is valid based on the flag of the exclusion and the interval defined in the table's).

  It is much easier to explain with an example.

  So here we go...

  Exclude_flag = E (exclude): for b.fs = 433638, b.na = 80000. I have 2 lines in the table for this fs.  Both have E exclude_flag (exclude).  I want to go on all the lines in this FS in the table in a query and I return only one row in the result, if and only if b.na falls out of scope of a.na_min_value and a.na_max_values.  In this example, it falls outside the range excluded for both lines (first two lines of the table a).

  Similarly, exclude_flag = I (Include). for b.fs = 432828, b.na = 17200. I have 2 lines in the table for this fs.  Both have an exclude_flag of I (include).  I want to go on all the lines in this FS in the table in a query and I return only one row in the result, if and only if b.na is between a.na_min_value and a.na_max_values.  In this example, it falls in the range of both the range include for the two lines (line 6 and 7 of the table a).

  The following query gives me two lines for each b.fs.  It is possible to get what I'm looking for simply using sql (possibly write the analytical function?) or I have to write the pl/sql routine for this?

  WITH rates_table

  Any help is greatly appreciated.  I use oracle 11i

  @OP,

  For this kind of problems, we get the number of rows that satisfy the required conditions or who do not meet the required conditions. And then eliminate the line that should be eliminated.

  As below, I calculate four counts (number of join lines)

  EOBCNT - excluded and Out of Bound

  EIBCNT - excluded and in the limit

  IOBCNT - included and Out of Bound

  IIBCNT - included and within the limits

  Once those are calculated, simply return the lines that have EIBCNT and IOBCNT are zero.

  For Ex:

• Order of evaluation of analytic function

  Hello

  have question quite like this:

  with

  -This query selects a 'representative' acct_id by Group (about 300 lines in total)

  acct_repres as

  (

  Select distinct acct_id, origin_id, acct_parm_id of

  (

  Select a.*

  source_id

  , dense_rank() over (partition by order source_id by nulls first, acct_id acct_nbr origin_id) as odr

  account a join account_parm on (a.parm_id = ap.acct_parm_id) ap

  )

  where odr = 1

  )

  Select col1

  col2

  , (select accct_id from ar acct_repres where ar.acct_parm_id = t2.acct_parm_id) col3

  , col4 (select count (1) of acct_repres)

  of une_table t1

  Join other_table t2 on (...)

  And here it is. "Acct_repres" subquery returns more than 300 lines when it is run separately. But when it is used in CTE sometimes (depending on the execution plan) she seems to have that one line - the value in the column col4 is '1 ',.

  While the value of col3 is NULL for most of the cases.

  It looks like the the dense_rank function and the State 'where odr = 1' are evaluated at the end.

  When I use the hint to MATERIALIZE the result was the same.

  But when I put the result of account_repres in the dedicated table and use this table instead of CTE output is correct.

  What is a bug? Or I do something wrong?

  PS: my version of db is 11 GR 1 material (11.1.0.7).

  some unorganized comments:

  -analytical functions are evaluated towards the end of the execution ("' the last set of operations performed in a query with the exception of the final ORDER BY clause"- http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions004.htm")

  -but still the result of a SQL query must be deterministic, so I think that your results are not an expected behavior

  -the CBO has some problems with common table expressions (http://jonathanlewis.wordpress.com/2012/05/24/subquery-factoring-7/) if they are of great assistance in the structuring of complex queries. In these cases, you can avoid problems by using inline views

  -Your query uses the common table expressions in scalar subqueries and scalar subqueries are also likely to confuse the CBO. In addition, they are executed once for each row in your result set (or at least for each different correlation value) and can have a negative impact on the performance of the queries in many cases. Often, they can be replaced by outer joins.

  -you say that the suspicion of materialization brings you an erroneous result: the indicator object (online) gives you the correct results?

  Net = Dealer_price - Discount price (of the 3rd day after the date of the day, so if we are calculating for 04/01/2013 then delivery must come from 06/01/2013)

  Net_ Price_ before_ discount = Dealer_price (of the 3^rd day before the current day, so if we are calculating for 04/01/2013 then the Dealer_price must come from 02/01/2013) - Discount

  I can achieve this LEAD and functions LAG problem I'm facing is that I need to calculate it only for a date range and some values (as shown above) fall not going so here it is coming as 0.

  1. for example when I am Net_price calculation for the 09/01/2013, the discount is from 11/01/2013, but as in my case clause I have a widow who allows me to get data only between 01/04/2013 and on 09/01/2013, the discount is coming up as 0.

  It's really complicated for me to achieve.

  Please suggest.

  AB

  Every time that you give examples of data give as CREATE TABLE and INSERT QUERIES or the WITH clause. Its easy when its this way rather than the data in a structure of table posted by you.

  You can use LEAD and LAG function like that. You must specify the OFFSET value to meet your need.

• Return one row of an analytic function

  Hello

  I pulled the following query:

  Select ID_STORNO, first_value (COD_CONTATTO) ON (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as COD_CONTATTO_LAST

  of WT_STR_ESG_CONTATTO;

  The result is:

  2160603	C1-H83J1N
  2160603	C8-9FOHXJS

  2258072

  C1-H83J1N

  But I just need to take the following lines

  2160603

  C8-9FOHXJS

  2258072

  C1-H83J1N

  Because for the same value of ID_STORNO, I just need to get a value of COD_CONTATTO (to select the best value using COD_PRIORITY and FT_DAT_OPEN_CNT). What is wrong inside the query? I just use 2 or 3 times the oracle analytic functions.

  Best regards

  As SomeoneElse... you need a where clause clause in order to choose the ones you want.

  To do this, the typical is to select a column that you use for this reason, such as:

  "I want to just the first record in each group..."

  Select id_storno, cod_contatto_last from)

  Select ID_STORNO, first_value (COD_CONTATTO) ON (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as COD_CONTATTO_LAST,

  ROW_NUMBER() OVER (Partition of COD_CONTATTO

  order of COD_PRIORITY asc, desc FT_DAT_OPEN_CNT

  rows between unbounded preceding and following unbounded)

  as rnum

  of WT_STR_ESG_CONTATTO

  )

  where rnum = 1

  /

  I prefer to use rownumber in this case, so I always have a rnum = 1...

  Usually, you must use the same partition/command by as your other folders (it is usually a good idea... maybe not, depending on your needs, however)
