Pump diagram remapping of data with the default value of sequence (12 c feature)

Hello

in the 12 c Oracle database there is a new feature that allows you to set default values directly from a sequence:

http://docs.Oracle.com/database/121/NEWFT/chapter12101.htm#NEWFT155

This helps us to save the use of triggers to get the next value of an ID column for example the DDL of such a table might look something like this:

CREATE TABLE "FOO"."MY_TABLE" ("ID" NUMBER(10,0) DEFAULT "FOO"."MY_TABLE_ID"."NEXTVAL", ...   );

During the pattern FOO with Data Pump export and import the schema with the remap_schema option in the BAR diagram for example, mapping works fine for all the tables, triggers, etc. except those defaults (as Oracle always writes the schema information in these default values).

The error in the output log that says 'FOO. MY_TABLE_ID"sequence is unknown, because the sequence is now called 'BAR. MY_TABLE_ID' - mapping so does not work for default values.

Someone knows how to fix this?

Thanks in advance

Concerning

Hello

Read this note, I think that it is an expected behavior:

http://docs.Oracle.com/CD/E11882_01/server.112/e22490/dp_import.htm#SUTIL927

REMAP_SCHEMA

.

Restrictions

* The mapping cannot be 100 percent complete because there are some references to diagrams that importing is not able to find. For example, import will not find of references to patterns incorporated into the body of the definitions of triggers, types, views, procedures and packages.  -I think in your case it is the default value.

* If any table in the schema are remapped contains object types defined by the user and this table changes between the time wherever it is exported and the time you are trying to import, and then import this table will fail. However, the import operation will continue.

  • Documentation about adding column with the DEFAULT value.

    Hello

    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241

    < quote >
    If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
    < quote >

    I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.

    According to the documents of 11 g

    http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105

    n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.

    This insistence is intended? If not, IMO, it should be changed.

    Kind regards

    Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

    When you add a column, the initial value of each row in the new column is null.

    * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

    This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

    * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

    Hope that helps to clarify the matter further.

    No, can't do this in the signature. You will need to manage this by validating the parameters passed at the beginning of the function.

    It is quite simple. In your case, you might as well test for NULL and fail to function like this:

        FUNCTION date_post_message(
                user_lock_in IN NUMBER,
                form_type_in IN NUMBER DEFAULT 0 ,
                date_in      IN DATE)
            RETURN BOOLEAN
        IS
            v_num NUMBER(1);
        BEGIN
            dbms_output.put_line('Value of parameters : user_lock_in : '||user_lock_in || ' : form_type_in : '||form_type_in||' : date_in : '||date_in );
            IF user_lock_in = 1 THEN
                RETURN FALSE;
            END IF;
            IF form_type_in IS NULL THEN
                RETURN FALSE;
            ELSIF form_type_in NOT IN (1,2) THEN
                RETURN FALSE;
            END IF;
            RETURN TRUE;
        EXCEPTION
        WHEN NO_DATA_FOUND THEN
            RETURN FALSE;
        END;
    

    In other cases of use I would issue a local variable and treat it like this:

            IF form_type_in IS NULL THEN
                l_form_type := 0;
            ELSE
                 l_form_type := form_type_in;
            END IF;
    

    Of course, the code should use the local variable rather than the parameter.

    It is a good practice to validate values passed in parameters at the beginning of a function. If you really want to go to the city, discover the Design By Contract.

  • XMLNAMESPACE with the default value of XQuery

    Need help on how to solve the problem of default namespace with the underside of XQuery. XQuery below works great when space default namespace ("xmlns ="http://abc.org/SampleRequest/one"") is removed from the XML SampleRequest element. Any help is appreciated.

    with table1 AS
      (select xmltype(

    You can declare a default namespace by using the DEFAULT keyword:

    http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_xquery.htm#autoId7

    for example

    XMLTable (XMLNamespaces (default ' xmlns.example.org', 'another_ns' as "ns0"),...)

    In your example, the default namespace is the same as that associated with the ns0 prefix, so simply precede the SampleRequest element:

    SQL > with table1 AS)

    2. Select xmltype)

    3 'http://abc.org/SampleRequest/one' xmlns ="http://abc.org/SampleRequest/one" >. "

  • Problem with the default value for OAMessageTextInputBean to the controller layout

    Hello

    I encountered this problem when I expand a controller for the page create a work request (/ oracle/apps/eam/workrequest/webui/EAM_WR_WORK_REQUEST_DETAIL_PL). My goal is to re - fill OAMessageTextInputBean 'Additional Description' after the user clicks "Save" or "apply". When I try to change the value of another field, it works correctly, the problem persists for 'Description Addidional' more precisely. I don't know that I have the correct id (I took it from xml received by jdr_utils.printdocument). The journal does not all controllers running after the attempt to set the value.

    Compare these logs:

    [21]:PROCEDURE:[xxfideltronik.oracle.apps.eam.workrequest.webui.xxPageRegionCO]:Goosfraba, pre-added!
    [21]:EVENT:[fnd.framework.webui.OAMessageTextInputHelper]:OAF LOG: Event : Get Attribute Value, in: oracle.apps.fnd.framework.webui.OAMessageTextInputHelper: View:null ,Attribute:EAM_WR_WORK_REQUEST_DETAIL_PL426_EamWrRqlog , Return Value without datatype conversion :4321
    [21]:PROCEDURE:[xxfideltronik.oracle.apps.eam.workrequest.webui.xxPageRegionCO]:Goosfraba, added!
    

    [Descriptive information, does not work]

    and:

    [64]:PROCEDURE:[xxfideltronik.oracle.apps.eam.workrequest.webui.xxPageRegionCO]:Goosfraba, pre-added!
    [64]:EVENT:[fnd.framework.webui.OAMessageTextInputHelper]:OAF LOG: Event : Get Attribute Value, in: oracle.apps.fnd.framework.webui.OAMessageTextInputHelper: View:RequestDetailsVO ,Attribute:PhoneNumber , Return Value without datatype conversion :null

    [64]:PROCEDURE:[xxfideltronik.oracle.apps.eam.workrequest.webui.xxPageRegionCO]:Goosfraba, added!
    

    [Phone number, works fine]

    Here is my code for the method of the processFormRequest controller:

    public void processFormRequest(OAPageContext pgCtx, OAWebBean wBean){
         super.processFormRequest(pgCtx, wBean);
        
         String description = pgCtx.getParameter("EamWrRqlog");
         log("Goosfraba: " + description, pgCtx);
    
         if(description != null){
              OAMessageTextInputBean additionalDescription = (OAMessageTextInputBean) wBean.findChildRecursive("EamWrRqlog");
              if(additionalDescription != null){
                   log("Goosfraba, pre-added!", pgCtx);
                   additionalDescription.setValue(pgCtx, description);
                   log("Goosfraba, added!", pgCtx);
              }
         }
    }
    

    A solution would be: -.

    1. create a transitional VO with an attribute, LongDescription.

    2 associate this attribute with the EamWrRqlog field.

    3. in the processFormRequest, set the TransientVO attribute value

  • prompt of dashboard works do not correctly with the default values

    Go ahead and skip this step then. I never did, but my colleague has mentioned that you can disable the RPD to be cached at all, so if you are in online mode and you still cannot manage the cache, assume that this feature is disabled.

    In addition, as I said above, I don't think it is a caching problem, it was just more precautionary, so I don't think it will be a big problem.

    Please let me know how the rest goes!

  • Mr President, how can I enter two rows at the same time with different default values that only the first line to use see?

    Mr President.

    My worm jdev is 12.2.1

    How to enter two rows at the same time with different default values that only the first line to use see?

    Suppose I have a table with four fields as below

    "DEBIT" VARCHAR2(7) , 
      "DRNAME" VARCHAR2(50),
      "CREDIT" VARCHAR2(7) , 
      "CRNAME" VARCHAR2(50),
    

    Now I want that when I click on a button (create an insert) to create the first line with the default values below

    firstrow.png

    So if I click on the button and then validate the second row with different values is also inserted on commit.

    The value of the second row are like the picture below

    tworows.png

    But the second row should be invisible. It could be achieved by adding vc in the vo.

    The difficult part in my question is therefore, to add the second row with the new default values.

    Because I already added default values in the first row.

    Now how to add second time default values.

  • Insert with the default

    Hello
    I have a table with the following structure
    Table-1
    Identification number
    name varcahr2 (100)
    S_NO default number 1

    now, when I run insert
    insert into the Table1 values (1, 'abc');

    It gives me error not enough values, but I have done s_no with the default value.

    You must always explicitly name your columns in an insert:

    SQL> create table table_1
      2  (id number
      3  ,name varchar2(100)
      4  ,s_no number default 1
      5  );
    
    Table created.
    
    SQL> insert into table_1 values (1,'abc');
    insert into table_1 values (1,'abc')
                *
    ERROR at line 1:

  • The default values on the retail block for dummy record gets inserted in detail blk

    Hi all

    I have a master block
    a block of detail and a detail for detail block block

    For every master I have or have no certain records in the block of retail

    for each master, I have a few detail records

    for each detail record I may or may not have the corresponding detail records

    Let's take an example
    I navigate a primary record to the detail record.
    in the 3rd block of retail, there is no record for the record in detail, but I have some default values.

    Now I navigate to the 3rd block of detail and I do not insert records and then exit the screen

    Here oracle asks me to save all the changes I made (I did no changes)
    and by clicking on Yes, there is a dummy record is created for a 3rd detail record

    Please help me

    Thank you

    This is the default values are to mark the block as being changed. That's why you get the message "do you want to save the changes.

    I suggest that you fill out elements of the base with the default values table and fill out the matching elements from the base on a prior insertion trigger table.

  • How can I validate a dropdown list NOT accepting the default value?

    I have a fillable form where I need the user to select their "number of employees". I've added several lines as their options in a drop-down list (1-10, 11-25, 26-50, 50 +). My question is "defult value" is set to "1-10" and people submit it without changing the correct value.

    I changed the value for default "-select -", but it allows them to always submit the form with the value entered.

    I guess I need some sort of validation script that will basically say - "If the value of this field is - select one - do not submit the form, but give an error that says 'Please select your number of employees' or something of the sort."

    Basically I just want what they choose something as opposed to just submit it with the default value.

    I looked everywhere and am not very good with JS.

    You can't have the default set to a possible real value. You need a value that must be selected.

    So for your sending script, you will need to test all your required fields to make sure that they are not at the default value.

    You make a variable that assumes that all required fields are filled and then check each field and if one still has the default value that you set your variable to 'false' and then when you have verified all of the fields that you test the value of the variable and only if she is true to send you the form.

    var bSumbit = ture; logical variable for test submission

    Test menu drop-down # of employees

    this.getField ("number of employees".). required = false; Disable the required property

    If (this.getField ("number of employees"). value == "-select one - ') {}

    Determine = false;

    this.getField ("number of employees".). required = true; Set the required property

    }

    {if (bSubmit)}

    your submit acation;

    } else {}

    App.Alert (' not all required fields completed", 0, 1);

    }

  • How to set the default value of a column?

    Hello
    While creating a table a lack that certain field value is set to a default value, like:

    create table t2
    (a number;
    b number not null);

    In this table, I want to put a value to a certain default value, as in the case where a value is not entered then a field will be automatically filled with the default value. How to do this?

    Very simple:

    create table t2
    (a number default 10,
    b number not null);
    

    You can also set a default value and keep it as NOT NULL, to prevent it from being updated with NULL value later.

    create table t2
    (a number default 10 not null,
    b number not null);
    

    You can probably get faster answers glancing http://tahiti.oracle.com/ to more simple questions, in which case you would be looking for.

  • The default value for a property with data of type boolean

    Hi all

    Is it a system preference setting, where the default value for a property with data of type boolean can be a Virgin? I want to keep the value by default in a vacuum, but every time I save the property even after empty selection, the default value changes to FALSE.

    In this case Boolean doesn't help you, you mayneed to create a chain of ownership and have true/false / "" as your list of values
