• The appropriate to a MAX on an analytical function syntax

  I am trying to apply a MAX function on a function analytically than doing a MAX as well. However, I can't understand the appropriate syntax. That's what I tried:
  

  SELECT MAX(MAX(t.col1) OVER (PARTITION BY t.col2) AS max_col
    FROM sample_table t;

  When I try to run the above query, I get a 't.col1 is invalid in the select list because it is not contained in an aggregate function or the GROUP BY clause error.

  You must encapsulate the query that has the analytical function in another query and then make the max in the outer query.

  Thanks for help

  Hello

  I think that you are not analytic function correctly.

  Analytical functions will be run for each line. Where as Group BY will run for groups of data.

  See example below for you reference.

  Example 1:
  
  -- Below query displays number of employees for each department. Since we have used analytical function for each row you are getting the number of employees based on the department id.
  
  SQL> SELECT e.department_id,count(*) OVER (PARTITION BY e.department_id) cnt_analytic
    2  FROM employees e
    3  WHERE e.department_id IN (10,20,30);
  
  DEPARTMENT_ID CNT_ANALYTIC
  ------------- ------------
             10            1
             20            2
             20            2
             30            6
             30            6
             30            6
             30            6
             30            6
             30            6
  
  9 rows selected.
  
  Example 2:
  
  -- Since I have used GROUP BY clause I'm getting only single row for each department.
  
  SQL> SELECT e.department_id, count(*) cnt_group
    2  FROM employees e
    3  WHERE e.department_id IN (10,20,30)
    4  GROUP BY e.department_id;
  
  DEPARTMENT_ID  CNT_GROUP
  ------------- ----------
             10          1
             20          2
             30          6
  

  Finally, what I'm trying to explain is - if you use the analytical function with the GROUP BY clause, the query will not give the ful menaing result set.

  See below

  SQL> SELECT e.department_id,count(*) OVER (PARTITION BY e.department_id) cnt_analytic, count(*) cnt_grp
    2  FROM employees e
    3  WHERE e.department_id IN (10,20,30)
    4  GROUP BY e.department_id;
  
  DEPARTMENT_ID CNT_ANALYTIC    CNT_GRP
  ------------- ------------ ----------
             10            1          1
             20            1          2
             30            1          6
  

• Try to use a function of Group on an analytic function

  Hello
  
  We use the Oracle 11.1.
  
  I have an analytic function that gives me the DENSE_RANK of lines groups. I would like to return the highest value of each group.
  
  The function looks like:
  

  DENSE_RANK( ) OVER (PARTITION BY METRIC ORDER BY sum(AEROBIC_EXERCISE_P1), COACHID)

  When I try to use:

  MAX(DENSE_RANK( ) OVER (PARTITION BY METRIC ORDER BY sum(AEROBIC_EXERCISE_P1), COACHID))

  I have get and error
  

  ORA-30483: window  functions are not allowed here

  Is it possible that I can do this?

  Hello

  Sorry, my mistake. You do not have an ORDER BY clause analytic it.

  COUNT (DISTINCT SUM (aerobic_exercise_p1)) OVER (PARTITION BY  metric)
  

  If you would post CREATE TABLE and INSERT statements, then I could test it.

• [8i] can I use an analytical function, or do I need a subquery?

  Hi all...
  
  This should be a quick. I hope I can solve my problem with an analytic function, but I don't know if it's possible. Can I use a subquery if I have to, but I'd really rather not.
  
  Here is a very simple version of what I'm trying to do:
  

  CREATE TABLE     test123
  (     field1          VARCHAR2(10)
  ,     field2          VARCHAR2(10)
  ,     my_date          DATE
  );
  
  INSERT INTO     test123
  VALUES     ('value1', 'a',TO_DATE('12/31/1900','mm/dd/yyyy'));
  INSERT INTO     test123
  VALUES     ('value1', 'b',TO_DATE('01/02/2010','mm/dd/yyyy'));
  INSERT INTO     test123
  VALUES     ('value1', 'c',TO_DATE('01/05/2010','mm/dd/yyyy'));
  
  INSERT INTO     test123
  VALUES     ('value2', 'a',TO_DATE('12/31/1900','mm/dd/yyyy'));
  INSERT INTO     test123
  VALUES     ('value2', 'b',TO_DATE('01/01/2010','mm/dd/yyyy'));
  INSERT INTO     test123
  VALUES     ('value2', 'c',TO_DATE('01/15/2010','mm/dd/yyyy'));

  I want the results:

  FIELD1     FIELD2
  --------------
  value2     a
  value2     b
  value2     c
  value1     a
  value1     b
  value1     c

  I started with the following query:

  SELECT     field1
  ,          field2
  FROM     test123
  ORDER BY     MIN(my_date)     OVER     (
                                               PARTITION BY     field1
                                               )                                -- removed DESC here
  ,               field2

  But the problem is the database has a date of 31 December 1900 ' as default / initial for any date field. I don't want these default values taken into account in my calculation of min. I tried to put a WHERE clause in my analytical function [WHERE my_date <>TO_DATE (' 12/31/1900 ',' mm/dd/yyyy')], but I kept getting an error message "missing right parenthesis", so it seems that you can not have a WHERE clause here... or I'm just something wrong?
  
  Moreover, it is a 8i database...
  
  Edited by: user11033437 may 20, 2010 17:16: took the 'DESC' criteria out of my order by clause. In my real application, I need DESC, but not the example.

  Hello

  A WHERE clause excludes rows in the results set. Whenever you want you can have a WHERE clause that was more limited (for example, something that would simply exclude MIN calculating values in the ORDER BY clause), then think CASE:

  SELECT       field1
  ,       field2
  FROM       test123
  ORDER BY  MIN ( CASE
                WHEN  my_date > TO_DATE ( '12/31/1900'
                               , 'MM/DD/YYYY'
                               )
                THEN  my_date
            END
             )     OVER     (PARTITION BY     field1)      DESC
  ,       field2
  ;
  

  This puts the lines for "Value1" first.
  The minimum my_date for "Value1" (after excluding the values of 1900) is later than the minimum for "Value2", so I think that you either made a mistake in the desired output, or you do not want sorted by descending order.

  As always, thanks for the display of the data of the sample and the results so clearly.

• Analytical function - max_distinct

  Hello world
  
  (a) I have a request tht returns multiple rows for a student
  
  (b) to simplify my query, is columns
  
  Student ID, Academic_Period, student, Expected_Graduation_Date status
  
  (c) If a student has several status codes
  AS - active
  THE - leave
  
  He gets 2 rows to display.
  
  (d) I want to show only the rows
  
  Maximum preference on the Date of graduation
  
  (e) so I made this calc:
  
  MAX_DISTINCT (Expected_Graduation_Date) OVER (PARTITION BY ID.)
  
  and received the error:
  data types incompatible number got date scheduled
  
  (f) so I did:
  
  MAX_DISTINCT (TO_NUMBER (Expected_Graduation_Date)) OVER (PARTITION BY ID.)
  
  and received the error:
  invalid number
  
  (g) so I changed to max on alpha field of: student status
  MAX_DISTINCT (student status) OVER (PARTITION BY Id)
  
  and received the error:
  invalid number
  
  (h) is the right function to use?
  What's doing FIRST_VALUE.
  
  Your ideas and your advice would be appreciated, tx, Sandra

  Hello

  You need not use analytical functions. Try to create these calculations to replace the columns where there are different values:

  student_status_last = keep max (student_status) (last dense_rank order by Expected_Graduation_Date)

  Expected_Graduation_Date_last = max (Expected_Graduation_Date)

• Consolidation of the unauthorized analytical functions

  Hi all, I have a calculated field named Calculation1 with the following calculation:
  
  AVG (Resolution_time) KEEP (DENSE_RANK FIRST ORDER BY RANK) OVER (PARTITION BY "The COMPLETE user groups". Name of the group, "notes report COMPLETE #7. Name of the resource)
  
  The result of this calculation is correct, but is repeated for all the rows in the dataset.
  

  Group Name      Resourse name    Calculation1
  
  
  
  SH Group            Mr. A            10
  
  SH Group            Mr. A            10
  
  SH Group            Mr. A            10
  
  SH Group            Mr. A            10
  
  SH Group            Mr. A            10
  
  ...............................................
  
  5112 rows

  I tried to create another calculation to have only one value for the couple "(nom dele de groupe, le nom de la ressource) like AVG (Calculation1) but I got the error: unauthorized consolidation of analytical functions"
  
  I have also seen inside the spreadsheet "Edit" Panel that the Calculation1 * is not represented * with the "Sigma" symbol I (like for instance a simple (field_1) AVG) and inside the SQL, I did not GROUP BY group name, name of the resource...
  
  I would like to see ONLY a line like:
  

  Group Name      Resourse name    Calculation1
  
  
  
  SH Group            Mr. A            10

  .. .that means I've grouped by group name, name of the resource
  
  Anyone know how I can get this result or any workaround?
  
  Thanks in advance
  
  Alex

  Hello

  You can do this completely in the workbook because you need to aggregate several times. You need computing rank as a calculated using Disco admin folder item.

  Then you should be able to use

  AVG (CASE WHEN STATUS = 1 THEN Resolution_time END)

  in the workbook.

• A question about the analytical function used with the GROUP BY clause in SHORT

  Hi all
  
  I created the following table named myenterprise
  

  CITY       STOREID    MONTH_NAME TOTAL_SALES            
  ---------- ---------- ---------- ---------------------- 
  paris      id1        January    1000                   
  paris      id1        March      7000                   
  paris      id1        April      2000                   
  paris      id2        November   2000                   
  paris      id3        January    5000                   
  london     id4        Janaury    3000                   
  london     id4        August     6000                   
  london     id5        September  500                    
  london     id5        November   1000

  If I want to find which is the total sales by city? I'll run the following query

  SELECT city, SUM(total_sales) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  that works very well and produces the expected result, i.e.

  CITY       TOTAL_SALES_PER_CITY   
  ---------- ---------------------- 
  london     10500                  
  paris      17000            

  Now in one of my books SQL (Mastering Oracle SQL) I found another method by using the SUM, but this time as an analytic function. Here's what the method of the book suggests as an alternative to the problem:

  SELECT city, 
         SUM(SUM(total_sales)) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  I know that the analytic functions are executed after the GROUP BY clause has been transformed completely and Unlike regular aggregate functions, they return their result for each line belonging to the partitions specified in the partition clause (if there is a defined partition clause).
  
  Now my problem is that I do not understand what we have to use two functions SUM? If we only use one only, i.e.

  SELECT city, 
         SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY;

  This generates the following error:

  Error starting at line 2 in command:
  SELECT city, 
         SUM(total_sales) OVER (PARTITION BY city) AS TOTAL_SALES_PER_CITY
  FROM myenterprise
  GROUP BY city
  ORDER BY city, TOTAL_SALES_PER_CITY
  Error at Command Line:2 Column:11
  Error report:
  SQL Error: ORA-00979: not a GROUP BY expression
  00979. 00000 -  "not a GROUP BY expression"
  *Cause:    
  *Action:

  The error is generated for the line 2 column 11 which is, for the expression SUM (total_sales), well it's true that total_sales does not appear in the GROUP BY clause, but this should not be a problem, it has been used in an analytical function, so it is evaluated after the GROUP BY clause.
  
  So here's my question:
  
  Why use SUM (SUM (total_sales)) instead of SUM (total_sales)?
  
  
  Thanks in advance!
  :)
  
  
  
  
  
  In case you are interested, that's my definition of the table:

  DROP TABLE myenterprise;
  CREATE TABLE myenterprise(
  city VARCHAR2(10), 
  storeid VARCHAR2(10),
  month_name VARCHAR2(10),
  total_sales NUMBER);
  
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'January', 1000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'March', 7000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id1', 'April', 2000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id2', 'November', 2000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('paris', 'id3', 'January', 5000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id4', 'Janaury', 3000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)
    VALUES ('london', 'id4', 'August', 6000);
  INSERT INTO myenterprise(city, storeid, month_name, total_sales)

  It is clear that thet Analytics is reduntant here...
  You can even use AVG or any analytic function...

  SQL> SELECT city,

• Analytic function to summarize

  Hi, I have a question regarding the analytical functions.
  
  SCENARIO OF
  I have two fields: TICKET_ID and TASK_TIME
  
  For each TICKET_ID, I have a task_time calculated as in the example:
  

   
  
  TICKET_ID                            TASK_TIME 
  
  112293                                 25                                    
  
  112294                                 1200                                  
  
  112294                                 40                                    
  
  112295                                 40                                    
  
  112296                                 60                                    
  
  112297                                 120                                   
  
  112298                                 60                                    
  
  112299                                 60                                    
  
  112300                                 180                                   
  
  112301                                 1440                                  
  
  112302                                 4320                                  
  
  112303                                 120                                   
  
  112304                                 306                                   

  TASK_TIME calculation is the following: IPTV_COUNT_TASKS_TIME (JTF_TASKS_B.Task Id: CREATION_DATE_UL)
  
  where:
  
  IPTV_COUNT_TASKS_TIME is a function of DB
  JTF_TASKS_B.Task Id is an area from runtime
  : CREATION_DATE_UL is a parameter after PERIOD
  
  
  As you can see the 112294 ticket I have 2 rows.
  What I want to achieve is the following: I would like to have average task_time (taking into account all tickets), but I don't want to count 2 times the ticket 112294
  
  So... What have I done?
  I create another calculated field named SUM (Task_time) where the calculation is: SUM (TASK_TIME) OVER (PARTITION OF TICKET_ID)
  and I got:
  

   
  
  TICKET_ID                            TASK_TIME 
  
  112293                                 25                                    
  
  112294                                 1240   
  
  112294                                 1240                                
  
  112295                                 40                                    
  
  112296                                 60                                    
  
  112297                                 120                                   
  
  112298                                 60                                    
  
  112299                                 60                                    
  
  112300                                 180                                   
  
  112301                                 1440                                  
  
  112302                                 4320                                  
  
  112303                                 120                                   
  
  112304                                 306                                   

  .. .and it isn't good, because, in order to calculate the AVG (TASK_TIME) I want to have only one ticket 112294 (and see only once the value of 1240)
  In other words, I need to summarize the task_time for each ticket and show the result only once for each ticket.
  
  Where is the error? How I do change the SUM (Task_time) calculation?
  
  Thanks in advance for any suggestion

  You can create the package in a schema, although usually an APPS environment I would create the package in the APPS schema because then you need not to grant privileges.

• Error installing Fallout 3:-'Default functionality', component 'Fallout3', file: E:\data2 cab, error "incorrect function".

  Original title: 'Incorrect function' Fallout 3

  I have Vista 32-bit, all the elements for Fallout 3. It starts to install then a box pops up saying characteristic-'Default Feature', component 'Fallout3', file: E:\data2 cab, error "incorrect function".  I have the original disc, no copy, I cleaned the disc. I don't know what else to do?

  Hi tsp2u61,

  Usually, when you get this error, it means that your CD cannot be read.

  You can check if the drive works in another computer to make sure that the disk is not damaged.

  You can try to copy all the contents of the installation of the drive on the local hard drive and install from there and check if you can install

  a. right click on the desktop, create a new folder and name it as Fallout 3

  b. Insert the diskette in Fallout 3

  c. Click Start and open computer.

  d. right-click on the CD / DVD drive and click Open.

  e. press the Alt key and click on modify.

  f. click on select all.

  g. still once, press the ALT key and click on copy.

  h. Ouvrezledossier Fallout 3 on the desktop.

  i. press the Alt key and click on paste.

• GGetting advapi32.dll error invalid function on bootcamp

  Original title: at the start, I am reciving an error "invalid function advapi32.dll" almost all start-ups. How can I troubleshoot this to clear the error?

  Do not know what is the origin, online searches, just trying to sell me programs to erase it. some answers say hardware problems, software. all my gear works as far as I can see, no errors in the hardware Manager.

  Win xp SP3.

  Thanks in advance for any help!

• 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...

• Using the analytic function

  Oracle 11g Release 2

  I'm assuming that the best solution is the use of analytical functions.

  create table test3
  ( part_type_id  varchar2(50)
  ,group_id      number
  ,part_desc_id  number
  ,part_cmt      varchar2(50)
  )
  /
  
  insert into test3 values( 'ABC123',1,10,'comment1');
  insert into test3 values( 'ABC123',1,10,'comment2');
  insert into test3 values( 'ABC123',2,15,'comment1');
  insert into test3 values( 'ABC123',2,15,'comment2');
  insert into test3 values( 'EFG123',25,75,'comment3');
  insert into test3 values( 'EFG123',25,75,'comment4');
  insert into test3 values( 'EFG123',25,75,'comment5');
  insert into test3 values( 'XYZ123',1,10,'comment6');
  insert into test3 values( 'XYZ123',2,15,'comment7');
  commit;
  
  select * from test3;

  NOTE: There are about 12 columns in the table, for brevity I only included 4.
  
  
  
  

  Post edited by: orclrunner was updated desired output and rule

  Hello

  Here's one way:

  WITH got_d_count AS

  (

  SELECT part_type_id, group_id, part_desc_id

  MIN (part_cmt) AS min_part_cmt

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

  OF test3

  GROUP BY part_type_id, group_id, part_desc_id

  )

  SELECT DISTINCT

  group_id, part_desc_id, part_type_id, min_part_cmt

  OF got_d_count

  WHERE d_count > 1

  ;

  Output:

  GROUP_ID PART_DESC_ID MIN_PART_CMT 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);
