• 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.

• 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

  SID

  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...

  MIN (part_cmt) AS min_part_cmt

  COUNT AS d_count (*) OVER (PARTITION BY part_type_id)

  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.

• Truncate output of analytical function?

  For example this query:

  Select month, sum (tot_sales) monthly_sales,.

  AVG (Sum (tot_sales)) (any order by month

  between 1 above and 1 below) rolling_avg

  orders

  where year = 2001 and region_id = 6

  Group by month;

  gives me an output which includes several decimal places for the rolling_avg column.

  Is there a way to truncate this? I tried to use the rounded outside the analytical function and surely enough, it didn't work. I can't think otherwise.

  You can use an external selection on the result of this query

  select trunc(rolling_avg) from
  ( rolling_avg query);

  If you look at the output above, it dates back in the min_dt_from_grp column.

  MY question is if the analytical function calculates for a particular/set group, which is by statute and for what min (date_from) partition is 25-apr-2007 for the GROUP H (Status column), then why I have different values returned by the query above in the min_dt_from_grp column.

  Hello

  Because you have specified an ORDER BY clause for the analytical function. In doing so, you calculate the rows on a window. Since you have not specified a windowing clause, the default applies:

  RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW

  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.

  Hello

  Don't you know that it is the analytical function used to access an earlier date for example table RRODUCT

  30/09/2004	1000	4

  and this table contains more than 1000 lines in difeerent years now, I want to get the amount in a given year and the previous year like this 20 + 15 + 12 + 4

  I need analytical control that find the previous year 2012 if my year 2013 or find out if 2010 my 2011 yeaar

  You can use the YEAR-1 right? SHIFT of analytic function can be used to access the previous line. Your condition is to get the value of the previous year and previous row not. If this isn't what you are looking for then can you post output necessary for data provided?

  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?

  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?

• 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)

• SQL using the analytic function

  
  Hi all

  I want a help in the creation of my SQL query to retrieve the data described below:

  I have a test of sample table containing data as below:

  State ID Desc

  MICHAEL 1 T1

  ACTIVE 2 T2

  T3 3 SUCCESS

  DISABLE THE T4 4

  The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.

  I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.

  Kind regards

  Raluce

  Something like that?

  I had to fix it.

  with testdata until)
  Select 1 id, "T1" dsc "DISABLED" status of Union double all the
  Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
  Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
  Select 4 id, "T4" dsc "DISABLED" status of double
  )

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and)
  ID in (select id from testdata where status = ' ACTIVE')
  or
  ID = (select max (id) in testdata when status = 'DISABLED')
  )

  STATE ID DSC

  '2' 'T2' 'ACTIVE '.

  Maybe it's more efficient

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and
  ID =)
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then id
  on the other
  (select max (id) in testdata when status = 'DISABLED')
  end
  )
