• implement the primary key on the field of forms

  Hello experts,
  
  I have a form with deptno single base table.
  dept_name and deptno. DEPTNO is a primary key in the database table.
  When I get the records, it prevents to insert the value that is duplicated in the deptno text box when I insert or update.
  
  the form I create a block with the base table, apply the primary key property of this Dept block. is Yes.
  then I put the key property primary deptno fields to yes.
  When I get duplicate records and then save, it prevents insertion but I want the following:
  
  I run the form, when I enter the first record, if it exists in the table can prevent to insert. also after the first record was inserted.
  If I insert to new deptno even into the next record, it must also prevent.
  
  Please help me.
  
  Thank you

  You have built your data forms to help block the "data block Wizard? If so, it already identified DEPTNO as the PK column. If it does not, or you have built your data manually block, you can open the palette property for the DEPTNO element and set the primary key property Yes. When this property is set on an element, the corresponding property of block, primary to apply key must also be set to yes. Please remember, however, that the Act of mark the DEPTNO as a PK does not 'Real time' checking for duplicates. Checking for duplicates occur when validation occurs. If you need a real-time duplicate check, you will need to write code to allow audits in double 'real time '.

  There are numrous examples in the forum to check duplicate in real-time as well as examples on the Internet. A search on Google for 'Check' the locker double shaped will give you lots of good examples.

• primary key for the table

  I have a Gr_order table that was settled long ago, and now he needs to be filled
  with some more search data.
  
  "Orderid" is a primary key for the table, but the question is how can I insert "orderid" in the insert statement in the procedure. I couldn't find any name sequence. There are 1230
  documents that must be inserted.
  

  Desc Gr_order
  Orderid  Number Primary key
  Desc     Varchar2

  INSERT INTO gr_order (orderid,desc)  
  VALUES (???, upper(each_pom.desc);

  Thank you
  Sandy

  You can find the code that inserts into the table and see if it uses the sequence ;-). A sequence is not 'attached' to a particular table - this is the insert statement to determine whether a sequence should be used.

  You can check if the table has a trigger - some developers like to emulate the behavior of MS - sql server by having a trigger on the table that selects in a sequence. If it has such a release, then you just do your insertions without specifying order_id. But if the table does not have such a release, then you cannot know if the table was originally filled using a sequence or not (unless you can find the instructions for inserting somewhere).

  Hi Dinesh,

  You can customize a KM to create a primary key on the target
  The target table will be created with the mention of the primary key constraint in the data target store.

  Steps: -.

  Customiuse creating target step of the table and I create $ step table.

  for example: -.

• queues the IMAQ image data type

  I'm trying to run multiple queues in the same loop entering IMAQdx images from several cameras, and then save to AVI. After reading the site nor a little, I discovered that the reason why I get only the last image of each bucket, repeated on all frames in the AVI file, is that the IMAQ image data type stores only the memory location for the image, not the image itself data. However, I don't see a better solution for the queues of the actual image data. What conversion could be the fastest / are in charge of the processor the lowest?

  

  For each image you must initial Image space.

  You can use something like this:

  

  You need to add initialization camera (s) and AVI. You must add the multicamera feature. Stop recording is missing.

• primary key on the form

  Hello
  
  I'm working on apex 4.0.2

• Problems with the primary key of the query string

  Moving from asp to php, to work with David Power's book: The Essential Guide to Dreamweaver CS4 with CSS, AJAX, and PHP.  Recycling of my brain, so starting from scratch in the learning process.

  Everything was going perfectly until I tried to add the primary key of a record in a query string.  I compared my code with the example code for the book, and everything matches.  When previewing the page in my browser and hover over the link which must pass the main code on the next page, the query string does not appear correctly.  It shows user_id = but no figure shows, as it is supposed to.  www.webpage.com/update_user.php?user_id=

  Here is my code: (Please note, <>have been removed, as I was unable to find a way view the code in the correct way here (copy/paste was doesn't work do not, nor insert syntax))

  ? PHP {?}

  ? PHP echo $row_listUser ['family_name'];? PHP echo $row_listUser ["FirstName"];?

  ? PHP echo $row_listUser ['username'];?       ? PHP echo $row_listUser ["admin_priv"];?

  a href = "update_user.php? user_id =? php echo $row_listUser ['user_id'];?" "Edit / has

  a href = "delete_user.php? user_id =? php echo $row_listUser ['user_id'];?" ' Delete / has

  ? PHP} while ($row_listUser = mysql_fetch_assoc ($listUser));?

  Any ideas that could help me understand why this part does not in particular would be greatly appreciated.  Writing to the database worked perfectly, I see that there are numbers in the database as user_id, and it is defined as my primary key in the configuration database.  Such a simple process that is causing me headaches!

  Thank you

  You have the code to request a copy in your folder:

  $query_listUser = 'SELECT user_id, username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  $totalRows_listUser = mysql_num_rows ($listUser);

  $query_listUser = 'SELECT username, first_name, family_name, admin_priv from users ORDER BY family_name ASC';

  $listUser = mysql_query ($query_listUser, $connSCFDIR) or die (mysql_error ());

  $row_listUser = mysql_fetch_assoc ($listUser);

  The $listUser table will contain the results of the second query, which does not include the field user_id. delete the redundant code.

• How to get the primary key of the node selected in af:tree

  Hi all
  
  I use JDeveloper 11.1.1.5.0.
  
  I want to get the primary key of the node selected in the af:tree element. I wrote the code below in SelectionListener:

          model.setRowKey(key);
     
          System.out.println(rowKeySet);
          System.out.println(rowKeySet.size());

  The result looks like this:

  [[oracle.jbo.Key[5 ], oracle.jbo.Key[6 ], oracle.jbo.Key[12 ],oracle.jbo.Key[14 ]]]]
  1

  I need the values of the last 2 nodes:

• How to add the primary key for the table with the existing data?

  The table is already busy data. There was no primary key before, so for each column, there are some duplicate values.
  
  I want to add a new column, which should be of the integer data type and can automatically incremented, from 001. I tried with Oracle SQL Developer, but it says "ORA-01758: table must be empty to add mandatory (NOT NULL) column. How can I do? Thank you!

  Hello

  Look for the [ALTER TABLE | http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_3001.htm#sthref4803] command to find out how to add a column (step (1)) and a (step (3)) constraint to an existing table.

  For the step (2):

  CREATE SEQUENCE  employee_id_seq
  START WITH  1
  ;
  
  UPDATE  employee
  SET     id  = employee_id_seq.NEXTVAL;
  

  When you create a sequence, START WITH 1 is the default value, so that the line is not really necessary above... I've included just to show how you could start with any number you have chosen.

• [SOLVED] Export Oracle SQL Data Modeler is missing a PRIMARY KEY on the DDL script

  I use data 4.1.888 maker to create an ER diagram and generate a DDL her script.

  The diagram contains more than 40 paintings, most of them have a primary key defined.

  For some reason any there is a table that has a primary key defined, but which is ignored when I export the model to a DDL script.

  It is the "wrong" key (even if it is checked that it is not found on the generated DDL script):

  

  This is where the key is set:

  

  And it is the preview of the DDL (Yes, primary key up there shows):

  

  This is what happens if I try to generate the DDL for just this (still not generated primary key) table:

  

  Has anyone had the same problem? Any ideas on how to solve it?

  There is no error in the log file, but when I run the generated DDL script there, and then I realized that I was doing something wrong:

  The table MEMBERS had a mandatory foreign key from another table, which in turn had a mandatory key against MEMBERS himself.

  So even if I could generate this primary key on members myself, and then run the the constraint definition that returned an error on the DDL script, I could not perform an insert operation on any of these two tables because of the constraint.

  I revised my design and realized relationships was not mandatory. I unchecked the mandatory box on the definition of the constraint and everything went well.

  I could reproduce the problem and the solution on a diagram with only two tables, so I'm sure that's it.

  Anyway, the Data Modeler is "a failed" silently in this kind of situation. It should be fairly obvious to an experienced designer that I was doing something wrong, but it is not so obvious when you deal with dozens of tables and all their relations and this is your first time using the Modeler.

  Thanks for your reply :-)

• Primary key for the case in (NVARCHAR2 datatype) in Oracle 10 g

  I have primary keys in my database which are of type NVARCHAR2. By default, the data is inserted in these columns as case sensitive, which means the insertion of these two 'ABCD' and 'Abcd' is allowed.
  
  Can I change the settings in Oracle so that primary keys are working in sensitive cases? I tried Oracle to raise an error if someone is inserting "Abcd" and if there is already a record with primary key 'ABCD '.
  
  Note: I use Entity Framework.

  The simplest approach is probably to create a unique index on the UPPER (your_key) function, i.e.

  CREATE UNIQUE INDEX case_insensitive
      ON table_name ( UPPER( key_column_name ) );
  

  If you want to replace the queries to be case-sensitive, so, you can change the NLS_COMP and NLS_SORT for each session and create all your index with these NLS settings by default, but that complicates life in general.

  Either said by the way, do you really need to use the NVARCHAR2 data type? Your really using characters that cannot be represented in your character of database primary keys are defined?

• How can I make sure that changes in a primary key (in the parent table) would also appear directly in the FOREIGN KEY in the child table?

  Forgive my question. I am very new to Oracle.

  How can I make sure that changes in the key primary supplier_id (concerning the supplier table) would also appear directly in the FOREIGN KEY (supplier_id) in the products table?

  Is that not all the primary key and FOREIGN KEY on?

  My paintings:

  I created 2 tables and connect to apply in the data base referential integrity, as I learned.

  CREATE TABLE - parent provider

  (the numeric (10) of supplier_id not null,)

  supplier_name varchar2 (50) not null,

  Contact_Name varchar2 (50).

  CONSTRAINT supplier_pk PRIMARY KEY (supplier_id)

  );

  CREATE TABLE - child products

  (the numeric (10) of product_id not null,)

  supplier_id numeric (10) not null,

  CONSTRAINT fk_supplier

  FOREIGN KEY (supplier_id)

  REFERENCES beg (supplier_id)

  );

  I inserted the following text:

  INSERT INTO provider

  (supplier_id, supplier_name, contact_name)

  VALUES

  (5000, 'Apple', 'first name');

  I expect that the supplier_id (5000) to the provider of the table also appears in the products table under key supplier_id having the same value which is 5000. But this does not happen.

  How to get there?

  Thanks in advance!

  Hello

  What is a foreign key in Oracle?

  A foreign key is a way to ensure referential integrity in your Oracle database. A foreign key means that the values of a table must appear also in another table.

  Ok!??

  What is now the right way to implement referential integrity in your Oracle database that the values of a table must also be included in another table?

  A foreign key referential integrity indeed enfore in ensuring that the value in the child table must have a corresponding parent key (otherwise you will encounter an error, as evidenced by "SomeoneElse"). However, it will never automatically insert a row in the other table.

  If you are looking for a solution that automatically inserts a record in the other table, maybe you should go for triggers:

• ODI 12 - problem with missing data in the store column data types

  Hello world

  We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.

  

  So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")

  Anyone can give an idea what could be the reason for this and how might be solved?

  Any ideas would be appreciated.

  Thank you in advance.
