• Validation auto-generated Primary Key not Null

  Hello
  
  I have a generated Assistant shape, that has a primary key that is generated automatically by a trigger before insert. In my form, primary key is initially empty and after that the user saves the form, then the primary key generates a number and that it fills in the form. I currently have a non-Null on the form validation, after that the user submitted the form and wants to update. How can I keep the validation non-Null on the form so that the user can write again at the start of the database, with the empty primary key field? Auto Wizard generates this out of the constraints of the table, and I would like to know if it is a validation required?
  
  
  Thank you
  Mary

  Well, you do NOT have NULL validation on the primary key point and that causes the problem that the user create folder? Started to run or remove the 'never '. I don't think it's necessary that you display as 'read only '.

• Trigger - use one to create primary key values

  I'm stuck on a simple use to do a TRIGGER that fires when you add new rows to a table and want to Developer SQL to add the primary key value.

  I seem to be able to relax, but it is not inserted the primary key but giving a SQL error: ORA-00947: not enough values.

  Here's what I have.

  CREATE TABLE HF_fishers

  (

  contact_id INT NOT NULL

  , name VARCHAR (25)

  , last_name VARCHAR (35)

  PRIMARY KEY (contact_id)

  );

  CREATE SEQUENCES HF_fishers_seq.

  Then I ran the following trigger:

  CREATE

  HF_fishers_seq_trigger RELAXATION

  BEFORE INSERTING

  ON HF_fishers

  FOR EACH LINE

  BEGIN

  IF (: new.contact_id IS NULL)

  THEN

  : NEW.contact_id: = NVL (: NEW.contact_id)

  HF_fishers_seq. NEXTVAL

  );

  END IF;

  END HF_fishers_seq_trigger;

  =============

  Then I executed the following SQL statement that gives the error.

  INSERT INTO HF_fishers VALUES('Jacob','Muller');

  But if I do everything is good except that it defeats the purpose of relaxation.

  INSERT INTO HF_fishers VALUES(1,'Jacob','Muller');

  MySQL has a nice 'AUTO_INCREMENT' command, but from what I understand in Oracle, I need to set up a trigger to automatically increment a column/cell, which in this case I use for the PRIMARY KEY.

  OK Jaramillo, I tried as you wrote, but what would be an INSERT statement correct?

  -After the code trigger of Jaramillo

  INSERT INTO HF_fishers (first_name, last_name) values ("Jesse", "Owens"); -I have the trigger but he made the mistake of duplicate key.

  INSERT INTO HF_fishers values (hf_fishers_seq.nextval, 'Jesse', "Owens");  -No trigger but get key duplicated,.

  INSERT INTO HF_fishers VALUES(:NEW_contact_id,'Jesse','Ownes'); -works without the trigger but the "get links" dialog box appears. So not much 'automatic' on this issue,.

  My mistake.  Here is the modified version of the trigger. I removed the CONDITIONAL clause and comes to be a part of the body of the trigger.

  So, I created the table, the sequence, the relaxation and ran the first two insert statements and it worked fine.  The third one you have invites SQL + or any tool you use to enter a value if she sees the ":" colon as a variable binding.  Colon only works in a trigger without asking for confirmation.

  Here is the code and my exit I ran home

  DROP TABLE hf_fishers CASCADE CONSTRAINTS PURGE;
  DROP SEQUENCE hf_fishers_seq;
  
  CREATE TABLE hf_fishers
  (
  contact_id   INTEGER NOT NULL
  ,first_name   VARCHAR(25)
  ,last_name    VARCHAR(35)
  ,PRIMARY KEY (contact_id)
  );

        :NEW.contact_id := hf_fishers_seq.NEXTVAL;
     END IF;
  
  END hf_fishers_seq_trigger;
  
  INSERT INTO hf_fishers(first_name, last_name)
       VALUES ('Jesse', 'Owens');  -- Works with the trigger
  
  INSERT INTO hf_fishers
       VALUES (hf_fishers_seq.nextval, 'Jesse', 'Owens');  --Works without using the trigger body code.

• Shape of the apex - how to get the primary key value manually?

  Hello
  
  Whenever I create form by using wizard Apex, he asks me to specify the trigger/sequence/pl/sql function to fill the primary key value.
  
  However, if I want to specify primary key myself (ie. undetermined generated automatically), how I can clarify that?
  
  Thanx

  Hello

  You mean by yourself: by hand or by a pl/sql?

  If you say by trigger, the system does not take on what number is sent. If you can give it "manually".

  May I ask what is the reason for this?

  See you soon,.

• How to create an entity with more than one primary key.

  Hello

  JDeveloper Version 11.1.2.4.0

  I am trying to create an entity object based on a table with 5 columns. The combination of them is unique.

  I do the five columns of primary keys, but when I delete a line I: RowAlreadyDeletedException, although always the line exists in the database.

  Also displaying the view sometimes I get Houston-25019: line entity oracle.jbo.Key [1 key 2 null null NULL].

  
  

  
  

  How to create an entity based on one object several columns in the primary key?

  I don't want to add an additional column to a primary key, because this table is used in many PL/SQL procedures, and I'm not sure that this will not affect the.
  

  Also using Rowid as a primary key should be avoided.

  Kind regards

  Pamela.

  As I said, the framework is not like that

  Check this old (but still relevant) blog of Sung Im on Table Whose Primary Key entity object can be NULL

  describing the reason behind the behavior you're seeing and the way around.

  Or you use the secondary key rather as described here Wael Abdeen Blog, how to look at the views - part 2 | Oracle ADF as a secondary key composed of more then one column can have null values.

• Difference between the immediate and normal constraint primary key value

  Hello

  *
  ERROR at line 1:
  ORA-00001: unique constraint (SCOTT.CUST_ID_PK) violated

  The above error violation even works for a normal constraints primary / unique
  
  So what is the use of the command
  
  immediate Set constraint cust_id_pk;
  
  
  Thank you

  So what is the use of the command

  In fact, the use of the command when you're dealing with foreign key constraints. As explained below

   SQL>  create table cust (cust_id number ,cust_name varchar2(25), supplier_id number);
  
  Table created.
  
  SQL> create table supp(supplier_id number);
  
  Table created.
  
  SQL> alter table supp add primary key(supplier_id);
  
  Table altered.
  
  SQL>  ALTER TABLE cust ADD CONSTRAINT fk_cust_supp
    2    FOREIGN KEY (supplier_id)
    3    REFERENCES supp (supplier_id)
    4    DEFERRABLE
    5    INITIALLY deferred;
  
  Table altered.
  

  To insert a line in the cust table without entering Ref provider table supp

  SQL> insert into cust values(1,'raj',111);
  
  1 row created.
  

  Line by 1 created successfully (attention this validation is not yet done) because the foreign key constraint is initially deferred.

  Now

  SQL> set constraint fk_cust_supp immediate;
  set constraint fk_cust_supp immediate
  *
  ERROR at line 1:
  ORA-02291: integrity constraint (OWNER.FK_CUST_SUPP) violated - parent key not found
  

  Since Ref no outs in extra table so forced provider violated.

  allows to insert a row in the vendor corresponding with the vendor id in the cust table id

  SQL> insert into supp values(111);
  
  1 row created.
  

  Now, try

  SQL> set constraint fk_cust_supp immediate;
  
  Constraint set.
  

  but now, if you try to insert a row into the table cust without this vendor id in table supp, it give error (since now forced to check from the inserted row, even will not wait for commit)

  SQL>  insert into cust values(3,'bob',222);
   insert into cust values(3,'bob',222)
  *
  ERROR at line 1:
  ORA-02291: integrity constraint (OWNER.FK_CUST_SUPP) violated - parent key not found
  

  Also, in the case of primary key constraints will be checked when you perform VALIDATION, otherwise that it will allow you to insert the second row.

  SQL> alter table cust add constraint cust_id_pk primary key(cust_id)
    2  deferrable initially deferred;
  
  Table altered.
  
  SQL> insert into cust values(1,'raj');

• With the help of several key values to find the data

  Hello, it's me again.
  
  I had a question out about data from database and display them on a page of the ADF on Jdev 11.1.1.3.
  
  And Mr. Daniel Atwood answered my question with this blog to follow, that wrote.
  http://www.avioconsulting.com/blog/datwood/2012/06/19/using-BPM-process-variable-ADF-form-retrieve-database-information-0.
  
  But I have another question on top that.
  
  The Mr.Atwood example is when using a value of key 'one', what happens if I have two key values, how to set?
  
  Here are some details:
  
  I have a table like this
  
  ID Type_code name
  0001 05 a-blabla
  0002 b 25-blabla
  0002 26 b-blabla
  0003-08 c-blabla
  0003 25 c-blabla
  0003 c 79-blabla
  
  What I want to do is after the entry of the ID (0003) and type_code (25), he will show me the result on three components of text entry in the ADF with the value 0003, 25 page and c-blabla.
  
  Currently, I use only ID to query the data, but I would use two key values to find specific data.
  
  Thank you very much for taking the time to think about it,
  
  Sincerely,
  
  Alto

  If you had multiple values to use for the request, one approach would be to create a display object. Whether you are creating the view object, in step 6, you will add two bind variables. Call a "pTypeCode" and call the other "pId". Click on the back button so that you're still in step 5, and modify the WHERE clause as follows:

  (ID = :pId) and (Type_code = :pTypeCode)
  

  After you have done this, double-click the Module of the Application and add your new view object. In the tab control of data, click the Refresh button. Expand your new view object tab of data control-> expand "French"-> note that you now have a new method called "ExecuteWithParams".

  Open your workflow diagram-> delete your existing "SetCurrentRowKeyValues" method-> made slide on your new "ExecuteWithParams" operation on the diagram. When you do so, you should see two settings you need to complete the dialog box. Just as you did before with the SetCurrentRowKeyValue method, set the values for the pTypeCode and the nest.

  Add the case of control flow of the new method to your existing view-> make the new method, the default value.

  On your form, remove the fields that have been placed here who uses the old object from view. On the tab of data control, drag the fields you want to be placed on the inside of your new view object form.

• Copy a record ang get its new primary key value

  Hello again everyone!
  
  I need to copy a record from a table at the same table. Here is the sample table and data:
  
  CREATE TABLE (PRODUCTS)
  ID INTEGER NOT NULL,
  DESCRIPTION VARCHAR2 (80).
  PRICE NUMERIC (9,2),.
  KEY ("ID") PRIMARY CONSTRAINT 'PK_PRODUCTS '.
  );
  
  INSERT INTO PRODUCTS (DESCRIPTION, PRICE) VALUES (' PRODUCT 1', 8.5); -You will receive 1 trigger ID
  INSERT INTO PRODUCTS (DESCRIPTION, PRICE) VALUES (' PRODUCT 2', 7.0); -You will receive 2 ID by trigger
  
  Now, I need to copy data from product 1 on a new line on the table.
  
  I would use the following SQL statement:
  
  INSERT INTO PRODUCTS (DESCRIPTION, PRICE)
  SELECT DESCRIPTION, the PRICE OF PRODUCTS WHERE ID = 1 - assuming that I want to copy 'Product 1'
  RETURN ID IN: NEW_ID
  
  But as far as I know, this is not supported by Oracle. Is there no workaround solution to solve the problem?
  
  I can't use procedures, functions, or something like that. Must be a SQL statement.
  
  Once again, thank you all for help.
  
  Best regards

  user9936895 wrote:
  INSERT INTO PRODUCTS (DESCRIPTION, PRICE) VALUES (' PRODUCT 1', 8.5); -You will receive 1 trigger ID
  INSERT INTO PRODUCTS (DESCRIPTION, PRICE) VALUES (' PRODUCT 2', 7.0); -You will receive 2 ID by trigger

  I really, really, really hope that your trigger uses a sequence to generate pk

  I can't use procedures, functions, or something like that. Must be a SQL statement.

  If your trigger uses a sequence to generate the pk, I hope that there is a clause which no values if the KP value is zero...

  If Yes, then you could just do:

  INSERT INTO PRODUCTS (ID, DESCRIPTION, PRICE)
  SELECT id_sequence.nextval, DESCRIPTION, PRICE FROM PRODUCTS WHERE ID=1 --Assuming I want to copy "Product 1"
  

• MySQL Insert with autoincremented primary key

  I did not before MySQL.  I try and hit a roadblock soon enough.

  I would like to insert new records and have the auto-generated primary key / auto-increment.

  So, I have attached a few screenshots.  The first is a screenshot of the MySQL settings for the table that I'm writing.  The second is the Labview code that I threw as well as I am trying to run.

  The complete of the error I get is:

  > Database Connection.viADO error: 0x80004005
  Exception occurred in the Microsoft OLE DB provider for ODBC drivers: [MySQL] [ODBC 3.51 Driver] [mysqld - 5.7.11 - log] field 'techniciansID' didn't is not a default value to create a NI_Database_API.lvlib:Rec - Command.vi-> NI_Database_API.lvlib:Cmd Execute.vi-> NI_Database_API.lvlibData.vi B tools insert-> Connection.vi in the database

  I know that this error indicates that the techniciansID has no default value and he won't write because of it... but since it is an AutoIncrement field, it seems like it should work.

  Any help would be appreciated.  Thank you

  Thad

  Setting to 0 did not work, but I understand it.  For some reason any when I was refreshing my tables in MySQL server and using the "Forward Engineer" feature, the changes were not multiplication.  I had to drop the schema of the database (attached image) and then do an "engineer forward."  I made the changes, but the tables and the columns still had the attributes of origin... guess they cannot be updated by the script during execution.

  After doing this and the original settings I had (autoincremented primary key), the insert works in MySQL and Labview.

  Thanks for all the answers.  They made me think and check some things I didn't have before.

• Get the value of the primary key next or previous

  Hi guys,.
  
  I use this interactive report with a Get Next or previous primary key value process.
  This works very well if you do not filter anything, because it will take you to the next ID.
  
  BUT, I can do this job, so I only get the ID of the selected (using filters) lines?
  
  It is obvious that you would like to, in the hollow of the page, the results of the international registration instead of all records.

  Hi Philippe,.
  I also went through the trouble of IR + disorders navigation of form and was very disappointed with the standard record Navigation. So, in the hope of finding a solution I trawled by google :) search results Fortunately, I found a blog of Simon Hunt, where he shares his solution with us (Blog of the SHUNT: http://simonhunt.blogspot.com/2009/12/next-and-prev-from-interactive-report-2.html).
  However, it was not enough for me, as I have many IRs with columns that have their display derived from a LOV values. His solution is great, a lot of pure sql to analyze :) Then, I took his code and adapted/customized to my needs. The steps are explained in a blog I did, where the code was included. http://tpetrus.blogspot.com/2012/03/record-navigation-in-Oracle-apex.html

• How to get generated automatically the primary key to create procedure

  I have a service of physical data corresponding to a table named ACCOUNT. The primary key on the table is called ACCOUNT_ID. There's a trigger on the database which generates the primary key value and adds it during an insert. I would like to have this primary key value returned by the procedure of creation of physical data service. Any ideas on how this can be done? Thanks in advance.

  as the primary key automatically obtained by ODSI leave a sequence in the DB and used during a procedure for creating

  Go to the design for the physical data service view

  Click the column which is filled from the sequence.

  In the Properties tab (bottom window), under general, for automatic numbering, click the 'Value' column, select sequence. You get a noise on some things have changed, just click OK. With AutoNumber = sequence setting, this column appears as optional (question mark).

  Just below that, for purpose of sequence, type the name of the sequence (you can also specify MYSCHEMA. In case the sequence SEQUENCE_NAME is under another schema).

  When you create objects SDO - leave the update vacuum column.

  that is if he were CUSTOMER_ID, your client would look like this...

• Engineering problems the surrogate with Unique key primary key

  SDDM 3.3.0.747 with 2 problems (at least so far).  I hope that the problem comes from this recruit SDDM and I forgot a setting. PROBLEM 1 I don't want to start a religious debate on substitution vs natural keys but I'm having a problem correctly both the logic model of engineering.  I'm a rookie when it comes to SDDM but have many years of experience with the Designer. By default, only I wish I had a natural UID (UK) and a surrogate mother based on a primary key UID (PK) which is used for foreign keys.  The problem I have with engineering is I can successfully engineer the substitute PK, engineer of the FK with the PK, but cannot get the unique key to contain surrogate keys in the child table.  If I check the identification property in relationships, the PK columns and the UK are included in the child PK and the United Kingdom contains no columns. The installation program, I've defined two reference entities, PROBABILITY and GRAVITY with unique keys natural defined.  I also have a child entity RISK_ASSESMENT with links to entities of the PROBABILITY and SEVERITY and both have the "use surrogate keys:": check box selected.  The unique key of the entity RISK_ASSESMENT includes links to PROBILITY and GRAVITY.  None of the entities have a PK or replacement of the defined keys and they all have the checkbox "Create a surrogate key" checked.  In addition the following preferences are defined: Data Modeling/model/logic NO checked - use and the first Unique key as primary key value NOT checked - name - Keep under the name of the from attribute Checked - entity carrier to create controlled key - use surrogate PROBLEM 2 key relationship when the foreign key columns are engineered I want names have a prefix 'FK_"but they don't.  Models are defined as follows: Data Modeler/assignment of Standard/Templates Foreign Key name: FK_ {children} {parent} foreign key column: engineer FK_ {Ref column} relational model/General checked Options - translation name Marcus Bacon apply

  Once more, I designed without removing anything and still no FK to the United Kingdom of the child.

  There is a synchronization problem in DM 4.0 EA1. This will be fixed for the production version.
