• Problem with Outer join and filter

  Hello
  
  I join two tables in the source using a left outer join. Outside of the join, I have a filter specified with condition TabA.C1 > TabB.C2.
  
  Now, when ODI generates the query it puts the left outer join on the filter condition as well. So he puts filter as
  
  where
  (1 = 1)
  And ((TabA.C1 = TabB.C1 (+)) AND)
  (TabA.C2 = TabB.C2 (+))
  And TabA.C10 > TabB.C14 (+)
  
  How to avoid this problem. I tried this performance on stage as well, always generated query remains the same.
  
  I use the incremental update of the IKM Oracle. My source and target are both on the same PB.

  Hi Chikk,

  If you analyze the data, you'll see it's OK to have the "(+)" to the filter...

  Anyway, if you want to drop it, leave it as inner join and put the "(+)" manually to the join object.

  This help you?

• Outer Join and joining several Tables

  Hello
  
  Oracle Database 10 g Express Edition Release 10.2.0.1.0 - product
  
  I have three tables AddProject, AssociateProjectLead, AddAssociate. Now I'm generating a report who will join AddProject and AssociateProjectLead for a list of all the projects, even if it doenst have a project coordinator. I used the outer join for this. However, if I want the name of the project leader, I need to search for AddAssociate table. By joining this table also, the outer join is no longer valid. Please see the result below

  How can I select all the values in table AddProject?
  
  Published by: Pramukh on August 23, 2012 12:18

  Hello

  I could get the result with a bit of modification

  select ap.projid,
         apl.associateid,
         aa.associatename
    from addproject ap
         left outer join
         associateprojectlead apl

         left outer join
         addassociate aa
      on apl.associateid = aa.associateid
  

  As a follow-up, I have a request more. In the report form, the user can select a particular project ID and the report should be generated as a result. For example;-he wants to see the results of the only "Proj08". I get the output as below, while the result should display only the details of 'Proj08 '.

  select ap.projid,
         apl.associateid,
         aa.associatename

• left outer join and the where clause for the table to the right

  I want to join two tables a and b, where a is a must and b is a result set in option. When I use a left outer join to a to b, I want to achieve:
  
  1. Select a single column, two columns of b (not the join columns)
  2 - even if theres no friendly on the join column does not return data from one.
  3. If there is a match applies when the criteria on column b (table in option)
  
  so, how can I avoid no_data_found in this case? When I apply where criteria for b, so it does not return the data from one, which is a must.

  Sounds like a regular outer join to me...

  select a.col1, b.col2, b.col2
  from   tableA a
         left outer join tableB b
         on (a.id = b.id and b.colX = 'X')

• outer join and LignesMax problem left

  I'm having a problem with the method and an sql join. My left table includes some documents that I want in the list, max 25 per page. These records have some notes are related in another table that is outer joined. When I specify the method in my cfoutput tag it includes my external joined table rows. So I could only go 5 records in my table left and 20 of my attachment table. What I want is 25 records in my table on the left and however the number of records in the table on the other that could be associated with these 25 records. Is this possible?

  I make two requests and avoid the outer join in this case:

• outer join and OR condition

  I have a query that is not working properly. I'm trying to join two tables and I or condition and outer join

  my query is as follow
  
  SELECT l.* FROM table1 l, table2 map
  WHERE (NVL(l.id, '-99') = NVL(map.id(+), NVL(l.id, '-99'))
          AND  l.TYPE = 'TKE')
        ) OR 
      (NVL(l.id, '-99') = NVL(map.id(+), NVL(l.id, '-99'))
  AND NVL(l.type, '-99') = NVL(map.type(+), NVL(l.type, '-99'))

    )

  So, basically in the above query I say that if the type = "TKE" do not join on all columns of pos. If type is not TKE then do all the joints on all columns POS etc.
  How do I rewrite query so that I can use OR and the outer JOIN in the same query?

  Hello

  It is one of several good reasons to use the ANSI join syntax. Move all the join conditions in the clause on, not the WHERE clause, and you do not use the sign +.

  SELECT  l.*
  FROM           table1 l
  LEFT OUTER JOIN  table2 map  ON   (    NVL(l.id, '-99') = COALESCE (map.id, l.id, '-99')
                                      AND  l.TYPE = 'TKE'
                        )
                               OR  (     NVL (l.id, '-99') = COALESCE (map.id, l.id, '-99')
                            AND   NVL (l.type, '-99') = COALESCE (map.type), l.type, '-99')
                       ...
  

  Instead of nesting the NVL statements, use COALESCE, as illustrated above. It is independent of the issue of the join.

  CHECK (regexp_like (law on the ' [[: digit:]] {4}'))

  Rgds,

  Athuru Mithuru.

  Let's start by defining precisely what you want.  For example

  1. The 1st character can be 0, 1, or 2.
  2. The 2nd character can be any number EXCEPT if the 1st character is '2', then the 2nd character must be in the range ' 0 'to 3'.
  3. The 3rd character can be '0' and '5'
  4. The 4th character can be any digit.

  It's pretty simple code like a regular expression with the exception of the exception in the 2.   Here's a way to get around that:

  REGEXP_LIKE (law on the)

  , ' (' || -options for the first 2 digits of start

  "([01][0-9])' |" --0 or 1, followed by another digit

  '| (2[0-3])'    || -2 followed by 0, 1, 2 or 3

  ')'              || -end of the options for the first 2 digits

  '[0-5]'          || -any digit between 0 and 5

  '[0-9]' - a figure

  )

  As others have said, think about the type of data.  How will you use this column?  If you really need a column which reflects a time of day, but not special, then perhaps an INTERVAL, or a NUMBER (for example, the number of hours after midnight) rather than a string.

• getting bad results with a query

  I have a column with the VARCHAR2 data type name (2) into a table and another table with a column named OFFICER_ZONE with the VARCHAR2 data type (1). What I'm trying to do is to compare these data and then insert it in the second table. But before you insert the data, if the AREA is equal to a number in double digits with a zero in front of her, then I need to CUT 0. If the BOX has a number greater than 9, then I have just these values to NULL. With the query below, I get the upper to 9 zones to be null, which is correct, but I also have those who are the two numbers with a zero not significant, which is not correct.

• records with an outer join restrictions while using a sub query?

  I have the following code:

  declare

  Default char Activeonly ' n ';

  SearchKey varchar2 (15) default '413041494500064';

  number of lclAcctNo;

  Start

  Select

  rat_acct_no in lclAcctNo

  ACCT,.

  marketer_account ma1,

  Marketing agent,

  Account_Service,

  Account_Address

  Where (Rat_Acct_No = Mka_Acct_No

  and Mka_Exp_Dt = (ma2 select Max (Mka_Exp_Dt) of Marketer_Account

  Where Mka_Acct_No = Rat_Acct_No)

  and mka_service_type = 'E')

  And Rat_Acct_No = Acs_Acct_No

  And Rat_Acct_No = Add_Acct_No

  "And Add_Address_Type s ="

  And Rat_Full_Css_Acct_No as Trim (Searchkey) | '%'

  And (Activeonly is Null or Activeonly = ' or (Rat_Acct_Status_Cd = 'A' or Rat_Acct_Status_Cd is Null))

  and rownum < 1000;

  dbms_output.put_line ('Account' | lclAcctNo);

  end;

  I'm doing the table MARKETER_ACCOUNT (MKA_fields) an outer join, because the data I expect to will not be on the table, but I want even when the table of ACCT.

  I can't do an outer join on subqueries, so wanted to know if there was a way more easy/better to Edifier cela?

  I use Oracle 11.2 g.

  Thanks for any help.

  Basically, I think, your outer join is ruined by the subquery correlated in the WHERE clause:

  R.ToDate = (Select MAX(ToDate) from R r2
  

  Since you joined outside R to A tell you the database to give you the lines of A for which R.ToDate is null * AND * meets your requirement: and this is not possible. Tom Kyte gave the classic explanation for this kind of problem long ago on AskTom: http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:4963137609733 ("ask yourself this - how a row in T2 (EMP in your example) the MISSING two (composed due to the outer join) AND have a column that corresponds to something?")  It cannot be").

  Here's your example in DDL + DML form: ''

  create table account)

  VARCHAR2 (10) key

  , name varchar2 (10)

  , status varchar2 (10)

  );

  insert into account values ('A1', 'John', 'Active');

  insert into account values ('A3', 'James', 'Inactive');

  insert into the relationship values ('R3', 'A2', 'M2', ' 01 /' 02/2013, 31 / 05/2013 ');

• Using Left Outer Join with reference

  I have three tables.
  Table 1: BOOK_DETAILS

  Table 3: BOOK_AUTHOR

  I must link table 1 and table 2 with a left outer join, because even if the book is not the questions to anyone, his name should come.
  I have once again display the name of the author of books for each book.
  I am able to create a query with the left outer join between table 1 and table 2. However, I am not able to give a reference to Table 3.
  Can someone help me with this please.

• Create a view which limits a large table, but also allows an outer join?

  INSERT INTO MY_ITEM_DISPLAY VALUES ('01 ', 20 '007', '013', '004',' 009');

  INSERT INTO MY_ITEM_DISPLAY VALUES ('01', 30 ' 001', '004', '009',' 011');

  INSERT INTO MY_ITEM_DISPLAY VALUES ('02', 30 ' 001', '004', '009',' 011');

  MY_PAY_ITEMS is a table that stores line of payslip items.  It has a total area of 500,000,000 lines.

  PEM is the unique id, we have about 200,000 employees (with about 50,000 being active today).

  PAY_PRD is a weekly pointer (2010-01, 2010-02, 2010-52), we have the 2004 data and add a new pay period each week.  2010 01 is defined as the first Monday in 2010 for the first Sunday in 2010, etc.

  Key1 is an internal key, it follows the chronology in the pay period.

  KEY2 is a child of KEY1, there follows the sequence of events in KEY1.

  LN_ITEM is the component of actual compensation resulting from the event, on average, a person produces 20 lines per event.  Note that in this example, everyone gets the same LN_ITEM values, but in practice it is selected 20 of 300

  ITEM_AMT is the net salary per command line.

  FILLING is a set of fields that are unrelated to this issue, but act as a brake on the charges of the line.

  MY_ITEM_DISPLAY is an array that describes how some screens should display items.  The screen itself is a grid of 4 poles, with the content of each cell is defined as a LN_ITEMS search to retrieve the relevant LN_AMT.

  We have an application that receives a DISPLAY_CODE and an EMP.  It automatically creates an sql statement in the sense of

  SELECT * FROM MY_VIEW WHERE DISPLAY_CODE =: 1 AND EMP =: 2

  and returns the output to the user.

  My challenge is that I need to rewrite MY_VIEW as follows:

  (1) (select the relevant lines from MY_ITEM_DISPLAY where DISPLAY_CODE =: 1)

  (2) select the relevant all MY_PAY_ITEMS lines that meet the criteria

  (a) EMP =: 2

  (b) PAY_PRD = (a more recent for EMP and sysdate, so if he got last paid 2010-04, return 2010-04)

  (c) KEY1 = (highest key1 in EMP and PAY_PRD)

  (d) KEY2 = (highest key2 in KEY1, PAY_PRD and EMP)

  (3) I then need to cross reference to create tabular output

  (4) Finally, I have to return a 0 line where there is no LN_ITEMs (DISPLAY_CODE 01, 40 sequence contains possible values for this scenario)

  The following query is part of it (but not the PAY_PRD, KEY1, KEy2)

  Select * from)

  SELECT A.DISPLAY_CODE

  B.EMP

  A.SEQUENCE

  , MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM1, B.ITEM_AMT, 0)) 'COL1 '.

  , MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM2, B.ITEM_AMT, 0)) 'COL2 '.

  , MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM3, B.ITEM_AMT, 0)) 'COL3 '.

  , MAX (DECODE (B.LN_ITEM, A.COLUMN_ITEM4, B.ITEM_AMT, 0)) 'COL4 '.

  OF MY_ITEM_DISPLAY A, MY_PAY_ITEMS B

  WHERE B.PAY_PRD = ' 2010-03'

  GROUP OF A.DISPLAY_CODE, B.EMP, A.SEQUENCE)

  WHERE DISPLAY_CODE = '01'

  AND EMP = '0000011'

  SEQUENCE ORDER

  My questions

  (1) how I do PAY_PRD, KEY1, KEY2 forced, can I use a form any of ROW_NUMBER() FUNCTION?

  (2) how can I deal with the fact that none of the 4 LN_ITEMS column can exist (see sequence 40, none of these can exist)...  Ideally the SQL above should return

  01, 0000011, 10, < a digit - > < number > - < a digit - > < some number >

  01, 0000011, 20, < a digit - > < number > - < a digit - > < some number >

  01, 0000011, 30, < a number--> < number > - < number > - < number > -

  01, 0000011, 40, 0, 0, 0, 0

  I tried a UNION, but it prevented the view to eliminate most of the MY_PAY_ITEMS lines, because it solves ALL MY_PAY_ITEMS instead of simply retrieve lines for the EMP passed to the view.  The same seems to be true for outer joins.

  Hi Paula,

  It does not handle SEQNUM 40, it's just that your second set of test data did not SEQNUM 40. When I put in the first set of values MY_ITEM_DISPLAY, I get:

  DISP EMP SEQUENCE COL1 COL2 COL3 COL4

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

  01 00000011 10 101.1 103.1 105.1 104.1

  01 00000011 20 107.1 113.1 104.1 109,1

  01 00000011 30 101.1 104.1 109.1 99.99

  01 00000011 40 0 0 0 0

  If this isn't the issue, you will need to explain the requirement of "outer join" and what you want more. Apart from his return nothing if there is absolutely no element of remuneration of the employee, this query will always return a line for each line MY_ITEM_DISPLAY for the display_code. If there is absolutely no data, no return line seems reasonable.

• OUTER JOIN query returns the results of JOIN IN-HOUSE 11.2.0.1.0

  I'm data transfer in 11.2.01.0 (Windows XP 32-bit) and I wanted to compare the sizes of table with the same Table name in two different patterns, ML and SILENT, with a FULL OUTER JOIN (to account for all the tables and NULL values in a diagram).
  
  The scheme of ML has 176 tables: schema TUT a 133 tables. The use of a standard INNER JOIN gives 131 paintings.
  
  I get precisely the results with a FULL OUTER JOIN I get with an INTERNAL JOIN (not the same NULL values so I know they exist).
  
  This happens in SQL-Plus, SQL_Developer and using Oracle Wire pilot of Data_Direct.
  
  Here is the code:
  
  Login: SYS as SYSDBA or SYSTEM (same results for either)
  
  SELECT M.TABLE_NAME, M.NUM_ROWS, T.TABLE_NAME, T.NUM_ROWS
  OF SYS. ALL_TABLES M FULL OUTER JOIN SYS. ALL_TABLES T ON M.TABLE_NAME = T.TABLE_NAME
  WHERE
  M.OWNER = 'ML' AND
  T.OWNER = 'TUT';
  
  Produce the same results with LEFT OUTER joins and RIGHT OUTER joins in ASI and Oracle (+) syntax.
  
  Any thoughts?

  Hello

  If you read what I posted, forget it. MScallion (below) gave the correct answerr.

  If conditions such as

  owner   = 'ML'
  

  in the WHERE clause, and then they will reject the rows of the result set formed by the join condition.

  The inner join returns only 131 lines where the two 'paintings' have the same table_names.
  The outer joins return multiple lines (133, 176 or 178) before the place WHERE the provision is applied , but the WHERE clause eliminates all lines except the 131 found by the inner join.
