  Hi all, finally I found the solution to this exception.

  I did the following steps to solve the problem.

  1. create a bean and use this method

  public void tooManyObjectsMatchExceptioHandeler() {}

  Add the code in the event here...

  System.out.println ("inside the Handeler");

  FacesMessage message =

  new FacesMessage ("Type your friendly message");

  message.setSeverity (FacesMessage.SEVERITY_ERROR);

  FacesContext fc = FacesContext.getCurrentInstance ();

  fc.addMessage (null, message);

  }

  Now, drag and drop the file above java projects in data controls in the browser of the application.

  

  2. drag a workflow method call (where u get exception as Houston-25013) and call this method as an activity of the exception handler,

  Now, do a right click on this--> definition of the page method call create or go to definition of the page--> create a link Action method and select the above method in the select and file def page this method call in the workflow then go to properties inspector set out fixed property (here name of activities of method call) u give.

• change a composite primary key

  
  Hello

  I have a table that has a composite primary key with 3 columns (col1, col2, col3)

  Now I need to change the primary key (col1, col2, col4) remove composite col3 replace with col4

  col1	col2	COL3	COL4	col5
  1	one	x	p	DFD
  1	one	There	p	DFD
  1	one	z	p	SD
  1	one	m	p	amplifier
  1	one	n	p	Try

  There are thousands of records in the table in the format above. How to make this change?

  Thank you.

  In this case, you will need to establish that if the change to the primary key makes sense - if so, you'll have to remove some lines to remove duplicates. I think that if this requirement has been raised at a request of the company, they will (should) have indicated what lines need to be maintained.

  If it is not sensible, you will need to go to the one who asked for the change and get them to change their mind or tell you what to do with duplicate lines.

  Out of curiosity, why did you change the primary key?

• How to create validation of business for a composite primary key

  Hi all

  I am newbie in oracle ADF and my knowledge is lacking in the validation of the company,

  My requirement is to display an error message when the user enter the same data into the table.

  Let me exaggerate I have a table which the composite primary key is defined on 2 columns, if the user does not have the composite primary key constraints, so I have to display the warning message.

  FYI, I use the version of Jdeveloper 11.1.2.3.0

  Please let me know the steps to create business for this rule.

  Thank you very much!!

  User, if you use adfbc, you have nothing to do because this behavior out of the box. When you create a model of your tables infrastructure creates the business rule for you.

• By specifying the Composite primary key (columns 4 and 5)

  Hi all

  I am new to Oracle Apex,

  I have a few paintings with a composite primary key (4 or 5 columns)... When I try to create a primary key constraint, it gives me only 3 columns!

  Any help please in how can I solve this problem?

  Thanks in advance

  You are probably using the workshop for this sql Object Explorer

  which seems to be limited to 4 columns on APEX 4.2.3

  best thing to do is to create manually using the sql commands in sql workshop, here's an example:

  {code}

  CREATE UNIQUE INDEX myui ON JC_ACCOUNT

  (TITLE_ID, FAMILY_NAME GIVEN_NAME, GENDER_ID, TELEPHONE_NUMBER)

  /

  {code}

  I hope this helps you

• identification of composite primary keys

  Hi mates,
  
  I am trying to identify a unique value in a particular table, so then I tried to look for the primary key of the table constraints:
  
  11:54:07 brunos@vvp > select constraint_name, constraint_type, index_name, owner of dba_constraints where table_name = 'CARD_TRANSACTIONS ';
  
  OWNER CONSTRAINT_NAME, CONSTRAINT_TYPE INDEX_NAME
  ------------------------------ ------------------------------ --------------- ------------------------------
  VVP PK_CARD_TRANSACTIONS P PK_CARD_TRANSACTIONS
  
  
  Then I looked at dba_cons_columns:
  
  11:56:22 brunos@vvp > select * from dba_cons_columns where constraint_name = "PK_CARD_TRANSACTIONS";
  
  OWNER CONSTRAINT_NAME TABLE_NAME COLUMN_NAME POSITION
  ------------------------------ ------------------------------ ------------------------------ --------------------------------------------------
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS CARD 4
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS METER 3
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS 2 OPERATION
  VVP PK_CARD_TRANSACTIONS CARD_TRANSACTIONS STATE 1
  
  
  
  I understand that in a single table, we have only 1 PK only. It is a composite primary key? I expected to see 1 single value, and then he showed me 4.
  
  
  Thanks in advance.

  It is a Composite key, you can see the column in position to observe order in the Composite key.

  Insert into demo values (2,1); -This should not
  
  Please help me... Thanks in advance...

  A quick way to do this is to create a unique index based on a function like this:

  create unique index demo_i1 on demo
  (least(one,two)
  ,greatest(one,two));
  

• A composite primary key column cannot be null

  Hi all
  It will be a silly question, but still, I would like to ask if a composite primary key column can be null?
  
  
  Thank you

  Rafi,

  Why you think he would be allowed?

• request for deletion with a composite primary key

  I have the following problem, which seems very simple, but I'm a bit at a loss :)
  
  I have a table T1 with composite primary key F1 and F2.
  
  There is a second table I want to use to delete records of T1 T2. It contains als F1 and F2.
  
  I want to do something like this
  

  delete from T1
  where T1.F1, T1.F2 in (select T2.F1, T2.F2 from T2);

  Of course, this does not work.
  
  There are solutions, but I find them unsatisfactory:
  -A loop of PL/SQL and passes the key one
  -Concatenate F1 and F2: where T1. F1 | T1. F2 to (select T2. F1 | W2M T2 F2); - but it's very ugly.
  
  Surely it must be possible in a simple SQL statement...
  
  Thank you!
  
  Rob

  delete from T1
  where (F1,F2) in (select T2.F1, T2.F2 from T2);

• Aggregation based on composite primary keys

  Hello
  
  I have a coherence cache which stores complex Java objects in the form of values in which I have to perform aggregation (County based on a composite primary key in the object). The key for the cache's UUID.
  For example:
  Class XYZ has properties a, b, c and d (all the java.lang.String type). I need to calculate the number of times a unique combination of values of a, b and c in the cache.
  
  I tried to use a ReflectionExtractor as:

  ReflectionExtractor[] xBiz = {new ReflectionExtractor(
            "getA"),new ReflectionExtractor(
            "getB"),new ReflectionExtractor(
            "getC")};

  Then, create a chained as Exractor:

  ChainedExtractor chExtractor = new ChainedExtractor(xBusinessService);

  Finally, I perform the aggregation such as:

  InvocableMap.EntryAggregator aggregator = GroupAggregator.Parallel
                      .createInstance(
                                chExtractor,
                                CompositeAggregator.Parallel
                                          .createInstance(new InvocableMap.EntryAggregator[] { new Count() }));

  Obviously something is wrong, but I get the exception:

  java.lang.RuntimeException: Missing or inaccessible method: java.lang.String.getB()

  When I do this for the aggregation based on a single property say a or b or c, the aggregation works very well:

  InvocableMap.EntryAggregator aggregator = GroupAggregator.Parallel
                      .createInstance(
                                "getB",
                                CompositeAggregator.Parallel
                                          .createInstance(new InvocableMap.EntryAggregator[] { new Count() }));

  with the result

  y1 -> 4

  for the sample data below.
  The expected result for Aggregetion based on several properties:

  Data in Cache:                Expected Result:
  A | B | C | D |                 x1,y1,z1  -> 2
  x1|y1|z1|Desc1|               x2,y1,z1 -> 1
  x2|y1|z1|Desc2|               x3,y1,z2 -> 1
  x1|y1|z1|Desc3|
  x3|y1|z2|Desc4|

  Can anyone comment on how to get the aggregate first? And also if the way I am using the extractor chained is correct.
  
  Thanks in advance

  I think you want to use a MultiExtractor who will then produce a table of the elements of the composite key on which you can then aggregate. This means that the array of items produced key can be properly evaluated for equality.

  If not, write a custom ValueExtractor which returns a single object (can be a concatenated string or a key object with equals/hashcode).

• Entity object - Validation of Composite primary key

  Hi people,
  
  Can someone help me to implement this? I have a custom table created with an entity object based on that. However, this table has a PK composed of three columns of number. The developer's guide says that PK validation should be performed inside the setter for the attribute using findByPrimaryKey PK, because for a simple PK validation is level of attribute, but in this case, I have three bombers distinct and three distinct attributes of PK, which makes the PK cross-attribute validation.
  
  I tried to implement this in the validateEntity() because it is cross-attribute, but still, the validation fails. In my view, which is related to the fact that when validateEntity() fires, the entity itself is already in the cache, and the call to findByPrimaryKey() causes BC4J return a single game. Here is the code inside the validateEntity() for me:
  

          // First validation: Primary Key Uniqueness
          if (this.getEntityState() == STATUS_NEW || this.getEntityState() == STATUS_INITIALIZED) {
              EntityDefImpl def = PeriodEOImpl.getDefinitionObject();
              EntityImpl period = def.findByPrimaryKey(getOADBTransaction(), getPrimaryKey());
              if (period != null) {
                  // ERROR: DUPLICATE KEY FOUND
                  throw new OARowValException( OAException.TYP_ENTITY_OBJECT
                                             , getEntityDef().getFullName()
                                             , getPrimaryKey()
                                             , "MSG_APP"
                                             , "MSG_NAME" );
              }
          }

  Y at - it assumptions that I am causing that validation always fail? Is there anyone who had the same requirement and implemented a working solution to this? I looked through the dev guide and other sources, but this simple and common requirement seems to be forgotten.
  
  Thank you very much and it concerns!
  Thiago

  You make a transaction fictitious attribute in the EO and do a Composite key of four attributes instead of three. This additional attribute must ensure the automatic error of the OA framework is not present. Now you can enter commands using validateEntity. Don't bother abt the value stored in the temporary attribute because it would be lost anyway.

• Update line programmatically with Composite primary keys

  Hi all

  I use JDeveloper 11.1.2.4.0,I want to update the program with two primary keys PK1_ID and PK2_ID line

  When I have a primary key I can do it by:

  /////////////////////////////////////////////////////

  Key = new key (new Object() {empid});

  Employees1ViewImpl vo = (Employees1ViewImpl) this.getEmployees1View1 ();

  Locate the line using key reference in the View object.

  Line k = vo.getRow (key);

  using this method, we can set the new FirstName

  k.setAttribute ("FirstName", "Vero");

  this.getDBTransaction () .commit ();

  ///////////////////////////////

  Is it possible to use the same code with more of primary key?

  
  

  
  

  
  

  Kind regards

  The key class contains an array of attributes that identify the line you're looking for. In your case, the key has two attributes

  Key = new key (new Object() {pkId1, pkId2});

  the rest of the method works as what.

• A composite primary key needs of the Unique ID column or not?

  Hello dear,
  I have a table that's the primary key is a key that is composed of two columns and there are like 5 columns of information. You think I'm going to use two columns as the primary key of this table or create a unique ID column.
  Example:
  Employees table:
  Services of table:
  
  The table of the problem is the Department managers:
  Now, I'll add employee id and service id in this table and Manager info etc... (info does not exist in the employee table), should I use as primary or create the id column in this table?
  
  Thank you very much.

  You must use the new ID as primary (alter table add constraint primary key,...) you cannot use foreign key as primary :)
