Join as a Condition

• VO join EOs 2: conditionally updating only 1 EO.

  I have a view object that joins the tables of 2 DB/EOs, mainly to display data attached in an ADF Faces table.
  
  However, I now apply for the user to be able to update the attached data. The user will be able to update the data that would go in one or both of the DB tables.
  
  Now, let's say that in a given table ADF Faces line, a user updates the data happens in A DB Table, but does not change the DB table B data. It seems that during the validation of the task flow operation runs, the framework commits data at the same time table DB A and B. This is not, I can present our application functionality - without going into details, it has to do with the UPDATE BEFORE and AFTER the UPDATE DB triggers.
  
  So, is there a way to configure or code so that the update only occurs when the DB Table, for which the data has actually changed? in other words, in the example above, since no data for table B has been changed, I would that the DB to update only to the Table has.
  
  I know that another approach is just to not use has the VO attached; However, it would be much more productive if there is a way to do it, where the question.
  
  Using 11g.
  
  Thanks for your help.

  Well, there is always a way to prevent the operation of update at the level of the entities.
  In the entity class that corresponds to table B, you can do the following:

      protected void doDML(int operation, TransactionEvent e) {
         if (operation != DML_UPDATE)
            super.doDML(operation, e);
      }
  

  Of course, you can examine the additional conditions, for example (in pseudocode):

      if ((operation == DML_UPDATE) && theUserHasReallyChangedThisEntity())
             super.doDML(DML_UPDATE, e);
      else
            super.doDML(operation, e);
  

• outer join and OR condition

  Hello world
  
  I have a query that is not working properly. I'm trying to join two tables and I or condition and outer join
  I get the error message

   ORA-01719: outer join operator (+) not allowed in operand of OR or IN
  
  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'))
  AND NVL(l.pos_22, '-99') = NVL(map.pos_22(+),NVL(l.pos_22, '-99'))
  AND NVL(l.pos_27, '-99') = NVL(map.pos_27(+),NVL(l.pos_27, '-99'))

  AND NVL(l.ind,'-99') = NVL(map.ind(+), NVL(l.ind,'-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.

  Hello

  Whenever you have any questions, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and the desired results from these data. I know that's not always easy, but it is really necessary. Compounds that, I do not understand your problem.
  It could be useful that simplify you the problem. If you were not interested in, say, the mta, gcc, tables msib and ood, would you still have the same problem? If so, forget all these tables and just after, CREATE TABLE and INSERT statements for the remaining tables and the results you want from this data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

  The query you posted will not exclude any line of mmt just because it doesn't have a corresponding line in the mtr; That's what the condition:

  and mmt.reason_id=mtr.reason_id(+)
  

  but it will exclude mmt lines if they do not have matching rows in other tables. Maybe you need + plus join and may under certain conditions non-join, such as conditions

  gcc.segment2 (+) = :P_ACCOUNT
  

  Too much. It's just a guess. Without seeing your sample data and the correct results, you should get from this data, I can't say.

• [Help] Join the query from 3 tables

  Hi, I'm new to database. I have a question about joining 3 tables, forgive me for my bad English.
  
  My paintings look like this
  
  Table 1: person (id, firstname, lastname)
  Table 2: AssignPersonAddress (id, personid, addressid, type)
  Table 3: address (id, phone, street, etc.)
  
  I need AssignPersonAddress table, because in my data structure, a person may have more than 1 address and address type must be registered (for example: private, work)
  
  
  I want to do a select query to the State any person with his private phone and work phone, like this.
  NOBODY | PRIVATE | WORK
  
  
  
  Right now my query looks like this
  

  select p.name , a1.tel AS Private, a2.tel AS Work
  from person p, 
  addresse a1 , 
  AssignPersonAddress apd1, 
  AssignPersonAddress  apd2, 
  addresse a2
  
  where p.id  = apd1.person (+)
  and apd1.adresse  = a1.id 
  and apd1.art = 'Private' 
  and p.objectid = apd2.person (+)
  and apd2.adresse  = a2.id 
  and apd2.art = 'Work'

  the problem is that I only get the person who has a private address and the job. But what I want is all anyone no matter if the person has only 1 or 2 address.
  
  As you can see I put the left outer join in where condition, but I always get the wrong result.
  
  
  THX in advance

  Hello

  See the Boneist first message in this thread:

  select t1.emplid, t1.repdt, t1.code, t1.hrs, nvl(t2.hrs, 0)
  from   tab1 t1,
         tab2 t2
  where  t1.emplid = t2.emplid (+)
  and    t1.repdt = t2.repdt (+)
  and    t1.code = t2.code (+)
  and    (t1.emplid, t1.repdt) in (select emplid, repdt
                                   from   tab2)
  order by repdt, emplid, code;
  

  As Boneist said, this fact corresponds to option (b)
  "(b) do just an outer join, with a condition EXISTS (or IN) in the WHERE clause to find corresponding repdts.
  The

  (+)
  

  an outer join are signs.

• Correct answer? (SQL)

  I read the question from a book.

  If we are forced to build an equi-join of 30 tables, how to join

  Have conditions?

  a. 30

  b. 20

  c. 29

  d. the number cannot be determined

  I wonder what is the correct answer to the following question, C or D?

  The book says is correct C.

  The theory says

  "To join the tables together n, you need a minimum of n-1 join conditions.

  For example, to join the four tables, a minimum of three joints is necessary.

  This rule do not apply if your table has a concatenated primary key.

  in this case more than one column is required to uniquely identify each row. »

  What should I answer if this issue was in a test 1Z0-051?

  I would answer D. Is this wrong?

  That's the problem with people who write these test questions.  They forget to check their questions of ambiguity.

  So, assuming that each table has a single unique primary key that relates to foreign keys in other tables, then the answer would be 29.

  However, suffice it to say there are 30 paintings, does not the number of columns is required of each table to perform joins, so the answer is that it cannot be determined.  If the other answers had said for example "at least 29" which would have been okay, but as it gives an exact "29", it is not necessarily true.

  I hate ambiguous questions.

• Studio-based members of financial reports

  Hello
  
  I'm building a HFM to the reconciliation report Essbase en (with a grid for HFM and a grid for Essbase + calc column with the values of essbase-hfm). Metadata between Essbase and HFM is synchronized.
  
  I want to generate the report as dynamic as possible, so for my selection of account HFM, I selected members of the basis of a hierarchy of void (Total assets that wraps to the Trial Balance).
  
  I want to reproduce this in Essbase but cannot figure out how to select the members of a hierarchy of sub base.
  
  Any help would be greatly appreciated.

  Hello

  EN studio, when you select members, you can make a preliminary selection. first of all, in the member selection window, select option ahead of upper right button (view) then you can put a list descendant (member) and Level0 and use new options to join these two conditions (you can use and/or to join)

  I hope it helps you.

  I don't think that you can easily do, apart from maybe a customized version of the form with a customized view of the underlying data.

  The problem you have is that data are presented on the screen with a view; in the definition of the view, part of the join to retrieve condition meaning object will be based on the presence of a code corresponding to the hr_lookups to get the code that represents the object. So, even if you took out of the logic of the field research (assuming that it is even possible to do), there is a high probability that the data 'free format' will not be found in any question.

• Other new lines in SQL script file and problem with SQL * more

  Hi all
  
  
  I would like to ask a question on the characters of new line inside files SQL scripts. I have a very long SQL query, stored in a file txt (ANSI encoding). Because query instructions are very long (several table joins and WHERE conditions) tried to separate, WHERE and ORDER BY clauses by inserting several new characters of lines (just hit the entrance) among them in order to improve the clarity of the source code. Now the problem is, whenever these newline characters are inserted in the file, apparently SQL * Plus cannot parse the file properly and gives me the following error message:
  

  SP2-0042: unknown command "FROM" - rest of line ignored.
  SP2-0734: unknown command beginning "myenterpri..." - rest of line ignored.

  The problem is definitely related to these new line because characters that when I remove them, the scripts runs without any problem. I would appreciate that you could kindly guide me how should I deal with this problem. Is there any SQL * Plus command to run to correctly interpret the new line characters?
  
  
  Thanks in advance,
  
  
  Kind regards

  Help out me

  Yes it gives Cartesian product and also you saidTN1 table a number of records. So you may be required to use a join or else condition in your case.

• Any suggestions on the elimination of the error ORA-01417?

  Just a question here. I'm developing a workbook in Discoverer Plus. I get a message ORA-01417 - a table can be external joined as another table. Just trying to see if there is a way to eliminate this error message. What I do is the following. I join table PA_EXPENDITURE_ITEMS_ALL to PA_EXPENDITURES_ALL. It is a standard join. Detail exists in master. Then I join PA_EXPENDITURES_ALL to PER_ALL_EMPLOYEES_F. Since I have a lot of spending on projects that aren't payroll/labor partner, my id of the person spending all the table is often null. This particular join must be an outer join, where I want to go back the detail that corresponds to a master document and detail that does not match. So far, nothing unusual there. The problem is that an employee may have multiple records in the employee file. Which would give me the detail data duplicate lines when I do not have a match, which would be bad. So what I do is to add a condition to test the article date of expenditure between the employee effective start date and the date of actual end of the employee. It is a condition that I add to the workbook. There is NO join defined between PA_EXPENDITURE_ITEMS_ALL and PER_ALL_EMPLOYEES_F. But what does the discoverer is when it generates the SQL, is to put the symbol of outer join on this condition. That does not seem logical, why he would do this. After all, I'm having some retail spending with no record of employee for them. So I have to have a way to deal with situations of nowhere. In any case, when I added this condition and try to refresh the workbook when I get the message ORA-01417. So I did some playing. I realized that if I build a condtion like that - AND ei.expenditure_item_date BETWEEN nvl(per.effective_start_date,ei.expenditure_item_date-1) AND nvl (per.effective_end_date, ei.expenditure_item_date + 1)
  then manually running a SQL query, I get good results. When I create this condition in discoverer, discoverer always ends by adding the symbol of the left outer join and I always get my message ORA-01417. Does anyone know of a sneaky way to keep discoverer of the addition of this symbol of outer join on my condition when discoverer built its SQL statement? I hope that I have explained the situation pretty well. Always a challenge to adequately describe a question.

  Hello

  The error ORA-01417 is a restriction of the database rather than an a discoverer. If you get wrong this discoverer entirely in. Here are some things you can do:

  1. you can set a condition:

  Nvl (per.effective_start_date, ei.expenditure_item_date) AND nvl(per.effective_end_date,ei.expenditure_item_date) OR ei.expenditure_item_date BETWEEN EI.expenditure_item_date BETWEEN nvl(per.effective_start_date,ei.expenditure_item_date) AND nvl(per.effective_end_date,ei.expenditure_item_date)

  GOLD tells discoverer an outer join cannot be used, and it is why the sign (+) will not be added. This is not a real outer join but might work, as the dates are never null in the per_all_employees_f table.

  2. you can create a folder complex, combining the fields you wanted two tables PA. Then outer join this folder to the employee record, including the date of track conditions.

  3. If you only want the name of the employee in the per_all_employees_f table, and then you could implement a search function to translate the person_id in name of the employee. The function could be brought from the workbook so no join would be necessary. You might have to cache the result in the output function.

• Dealing with maps

  Hi all
  
  I have two tables that I'm under certain conditions to join a specific condition in the expression of the join operator that is only the first part of an if statement. Operator to join even how I implicitly understand the continuum of the other as I'm just another arrow that represents the condition else and no need to create another join operator representing the explicit if condition else condition? Please refer to the following pseudocode:
  
  Join tables 1 and 2.
  
  If the variable x is not null
  then include records with not null for table 3 variable x
  on the other
  include records with the variable x = null, table 4.

  Hello

  After joining tables 1 and 2

  spend everything, including the variable x to Splitter and

  In a group take variable x is not null
  join table 3

  In the second group to take variable x is null
  Join the in table 4.

  Then union them.
