Join conditions, update a table

• Under certain conditions, update a table based on the comparison with a SQL statement

  I have a table (table 1) that has 4 columns:
  
  UID. THE NEST | VALUE1 | VALUE2
  
  I have another statement SQL (STMT) that returns the 3 columns of a few other tables:
  
  UID. THE NEST | VALUE1
  
  Now this is the condition of the way in which I want to put up-to-date TABLE1:
  
  First, to compare a pair of UID and PID of STMT with those in TABLE1,
  
  -1, for any new pair UID and PID not in TABLE1, insert a new line of STMT in TABLE1 set TABLE1. Value2 = 0 (I already did this).
  
  2, for an existing UID and PID pair in STMT and TABLE1, do:
  
  a. in TABLE1. Value2 > 0, update TABLE1. VALUE1 = STMT. VALUE1
  
  b. to TABLE1. Value2 = 0 and if TABLE1. VALUE1! = STMT. Value1, update of TABLE1. VALUE1 = STMT. Value1, otherwise nothing to do.
  
  I can't seem to come with a solution for condition 2. Any help is appreciated!

  Hello

  Here's one way:

  MERGE INTO  table1  dst
  USING          (
               SELECT  ...   -- your stmt query goes here
           )   src
  ON         (    src.uid  = dst.uid
           AND      src.pid  = dst.pid
           )
  WHEN MATCHED THEN UPDATE
  SET           dst.value1 = CASE
                                 WHEN   dst.value2 > 0
                      OR     (   dst.value2 = 0
                           AND dst.calue1 != src.value1
                      )
                      THEN   src.value1
                             END
  WHERE   dst.value2 > 0
  OR (    dst.value2 = 0
     AND  dst.calue1 != src.value1
     )
  ;
  

  This assumes that the combination (uid, pid) is unique in stmt. It doesn't have to be unique in table1.

  FUSION could also do parts 1 and 2 together, in the same statement.

  2, for an existing UID and PID pair in STMT and TABLE1, do:

  a. in TABLE1. Value2 > 0, update TABLE1. VALUE1 = STMT. VALUE1

  b. to TABLE1. Value2 = 0 and if TABLE1. VALUE1! = STMT. Value1, update of TABLE1. VALUE1 = STMT. Value1, otherwise nothing to do.

  Why are they not simply your needs ' uid and pid that already exist in stmt and table1, if table1.value2 > = 0, then the value table1.value1 = stmt.value1 "? Are you concerned about shooting triggers unnecessarily? It has something to do with null values? The MERGE statement above does exactly what you asked, but, depending on your needs, something simpler and more efficient could do it as well.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

  Why? Suppose table A has three lines id = 1,2,3 and table B has 4 lines, id = 1,2,3,4. A.id = b.id condition will return 3 rows. But condition a.id! = b.id will not return 1 row. Why? A.id condition! = b.id will be true for:

  a.ID = b.id 1 = 2

  a.ID = b.id 1 = 3

  a.ID = b.id 1 = 4

  a.ID = b.id 2 = 1

  a.ID = b.id 2 = 3

  a.ID = b.id 2 = 4

  a.ID = b.id 3 = 1

  a.ID = b.id 3 = 2

• Trying to update a table in a second table when the data are different

  Hello;
  I have a the same table in two databases. The database are connected with a DB link. I'm trying to update one table based on the data in the second table when the EMP_ID is but the name does not match.

  There is no WHERE clause in the UPDATE statement, so that each row in the target table will be changed.
  If you only want to change the lines that have a match in the source table, then add a WHERE clause (perhaps "WHERE EXISTS (...)) with a subquery miuch very similar to the one you already have), or use the MERGER instead of UPDATE.

  If you want to know, post CREATE TABLE and INSERT statements to recreate the tables they existed before the UPDATE and also post the contents of the table changed after the UPDATE.
  Always tell what version of Oracle you are using.

  Maybe you want something like this:
  {code}
  MERGE INTO the emp target
  WITH THE HELP OF)
  SELECT o.emp_id
  o.last_name
  o.last_name
  o.middle_initial
  OF emp@other_db o
  JOIN emp t ON o.emp_id = t.emp_id
  AND o.last_name! = t.last_name
  ) source
  WE (target.emp_id = source.emp_id
  WHEN MATCHED THEN UPDATE
  SET target.last_name = source.last_name
  target.first_name = source.first_name,
  target.middle_initial = source.middle_initial,
  ;
  {code}
  assuming that emp is unique, at least in other_db.

  It will work in Oracle 10 (and more). In Oracle 9, MERGER still requires a WHEN MATCHED clause, so add one if you must. No matter what he does; the subquery USE will only return matches.

• OLAP cube - complex join condition

  Hi Experts,
  
  I requires a complex join between the dimension and cube.
  
  Requirement goes like this-
  
  We have a dimension to the date level-
  January 1, 2011
  January 2, 2011
  ...
  .. and so on.
  
  The fact table is not a matching surrogate key, but it has valid_from_date and valid_to_date that are stamps.
  
  I need to join these two to reach the condition readings - where dim.date between trunc (valid_from_date) and trunc (valid_to_date).
  
  Is it possible/feasible? Enjoyed your responses.
  
  Best regards, Marion

  You should be able to set a condition like this in the field "Join Condition" of the mapping pane cube in AWM. You would need to qualify table names to be something like this

  dim_table.date between trunc(fact_table.valid_from_date) and trunc(fact_table.valid_to_date).
  

  The only restriction to this approach is that you will not be able to partition on the time dimension for this cube due to the complexity of the condition.

  As an alternative, you can define a SQL view that joined your fact table in your time dimension table using the same condition. You map the cube on this point of view, in which case the restriction on partitioning goes.

• Join condition of cube and other mapping missing mapping

  Hi David,
  
  I have a strange problem... After the creation of cube mapping tables defning and physical objects joins and the change of my mapping intermittently disappears... Not being able to trace what's happening. Is this a known bug or nothing is done correctly?
  
  Enjoy your previous answer.
  
  Thank you very much
  Paiva

  A "mapping" is a term of olap product management which means that the cube is not mapped to the level the fact sheet. For example, suppose you have tables like this

  CREATE TABLE SALES_FACT
  (
    DAY_OF_SALE DATE,
    PRODUCT_ID NUMBER,
    UNITS NUMBER,
    COST NUMBER
  )
  
  CREATE TABLE TIME
  (
    DAY DATE,
    MONTH NUMBER,
    QUARTER NUMBER,
    YEAR NUMBER
  )
  

  Suppose you want to analyze the data only at the level of the MONTH and more. In this case, you must set a time of hierarchy which includes levels MONTHS->->-> ALL_TIME YEAR QUARTER and you would need to define a join condition between SALES_FACT and TIME of the form

  SALES_FACT.DAY_OF_SALE = TIME.DAY
  

  This is sometimes called a "mapping" because it maps data in the AW to a higher level than what is stored in the fact (for example, the MONTHS instead of DAYS).

• Update target tables...

  Hello
  
  I'm actually in a difficult situation. I need to update a table with a view. The table has 3 columns (* col1, col2, col3 *) initialized as NULLs in all records, noting that the other columns are given inside... So what I'm basically doing is this:
  
  I maps the columns to display in the table and click on the table to display the table operator properties, then set the type of loading for UPDATE. Then under a conditional loading in the filter of the target for the update , I have inserted the following condition:
  
  (INOUTGRP1.*col4 * IS NOT NULL) which shows a successful validation.
  
  Taking into account the constraints Match is chosen to be NO_CONSTRAINTS...
  
  After that I click on col1, col2 and col3 respectively to put the Match column when new line Yes...
  
  Unfortunately, these warnings will appear saying the following:
  
  + VLD-2753: all mapped attributes are used in corresponding to the criteria of 15_REC.
  
  It will be a meaningless update action if all attributes are mapped are used for matching. The update statement selects rows that meet the condition of correspondence and be updated with the same values. Specify at least one mapped attribute of my_table to use for updating by setting use update for Matching No.: ( COL1 COL2 COL3). +
  
  
  + VLD-2761: impossible to generate the Merge statement.
  
  MERGE statement cannot be generated because the COL4 column is used for correspondence and updating. A column can be updated in a merge statement. +

• Programatically update af:table when clicking on createInsert af:button

  Hi all

  I use JDeveloper 11.1.2.4.0.

  Requirement:

  I have an af:panelCollection, inside I have a (Add) af:button and an af:table. Af: button creates an empty line in a table as createInsert. Now when I click on the Add button, it creates the empty line in the af: table. But the blank row is not visible immediately. It is visible only when I do another action in this page, as on some other tab and back.

  From my observation, I found that the updating of the table does not occur immediately.

  I want to create a blank line like createInsert done and immediately refresh the table so that the empty line is visible in the table.

  I tried to adjust the partialTrigger of the tab; the reference to the id of the af: button, but still not working.

  I tried to update the table in a pragmatic way during the click on the button, but did not work.

  Can anyone suggest me solution for this.

  Thank you and best regards,

  Susanto

• ORA-01445: cannot select ROWID, or sample, a view of join without key - preserved table form w/report and LOV

  I create a page "Form on a Table with Report" (APEX 5). Table I has 3 columns: cat_key, item_value, item_description. The cat_key is a foreign key in a table with columns cat_key, cat_value. I created the report and everything works fine.  The page of the report shows my domain cat_key in number, so I want it instead to display the cat_value. I change the field cat_key to a text based on LOV, select my LOV and now when I view the page of report I get the "'ORA-01445: cannot select ROWID from where sample, a join without key preserved table view ' error." The report uses the ROWID as a link to the edit page field.

  If I use the same tables and even shared LOV in a report page interactive, it works fine.

  What I am doing wrong?

  This is a limitation of the IR Apex will rewrite your query to a query that includes the lookup table and the columns. So now you have actually created a query on an inline view, which causes the error. You can see the query apex created when running in debug mode. APEX will join the table of choice with your primary table. For example from one of my IR:

  Select 'ID '...

  "MSL". "" HIS_COUNTRIES "=> my primary table

  ) ) b,

  (select rv_meaning d, rv_low_value r

  of msl_ref_codes_table

  where rv_domain = "JOHN".

  ) L1 = > query My LOV Lookup
  

  ...

  So, if possible, base your reports and forms on the real primary key, no rowid.

  You can also write the IR query with the search yourself:

  Select T1.rowid...

  of primary_table T1

  look_table L1

  ...

• How do I update the table in Jdev

  Hello

  I use Jdev 11.1.1.7.1.

  The control of data, I added that ADF only read the table. When I click on the button create and return to the report screen, highlight lines are added.

  Highlighted those who is not inserted into the DB table but he showed in the report. How to remove it. How can I update the table?

  

  Kindly advice me.

  Thank you

  Swathi

  That's what I got:

  -You have a table read-only, and a link to create.

  -When you press the link create a popup will be launched with a new record (may be a form in the same table iterator).

  -When you press save to save the changes validation triggers, stop you to insert the record.

  -After the fire of validation you will close the pop-up window (by pressing icon or by pressing Cancel).

  -After closure of the pop-up window, you will find that reading one table has some blank lines.

  If it is your problem if you have 2 choices:

  1. in the AppModule you can make a new instance on the view object (to which redirect the table) If your view object called 'EmployeesView', so, in AppModule, you should have EmployeeView1 and EmployeeView2 and your table may point to EmployeeView1, and when you create new line create in EmployeeView2 and after completing the creation you can run the query and then refresh the table (as shown in the following code).

  2 - the second option in the popup cancelListener link at the rear bean method then you can update the table by program as:

      DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("TableIteratorName"); // from pageDef.
      iter.getViewObject().executeQuery();
      RequestContext.getCurrentInstance().addPartialTarget(getTableComponent());// from table Binding property bind it to object in back bean

  Simply add partialTrigger on table pointing to the button.

  It will update the table when the button is clicked.
