• 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 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:
  

      public void drzewkoRwaSelectionListener(SelectionEvent evt) {
          RichTree tree = (RichTree)evt.getSource();
          TreeModel model = (TreeModel)tree.getValue();
          RowKeySet rowKeySet = evt.getAddedSet();
          Object key = rowKeySet.iterator().next();
          
          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:
  1: oracle.jbo.Key [14]
  2: oracle.jbo.Key [12]
  
  How can I get?
  
  Kind regards
  Wojtek.

  Hello

  Try this code:

  {} public void drzewkoRwaSelectionListener (evt SelectionEvent)
  RichTree tree = (RichTree) evt.getSource ();
  Model TreeModel (TreeModel) = tree.getValue ();
  RowKeySet rowKeySet = evt.getAddedSet ();
  Key of the object = rowKeySet.iterator () .next ();

  model.setRowKey (key);

  System.out.println (rowKeySet);
  System.out.println (rowKeySet.Size ());

  Object [] keys = rowKeySet.toArray ();
  List (list) = keys [0];
  Keys = list.toArray ();
  * //from the table keys, you can get according to the value you want using as: [2], [3] key *.

• 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.

• 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.

• How are there many Types of primary keys

  Hi all
  
  In one of the interviews, asked me how many types of primary keys is here.
  
  I said two types, one for a column, and the other on the set of columns (primary key). But I got a response that there are actually 3.
  
  Can you get it someone please let me know what is the third type.
  
  Appreciate your help.
  
  Thank you
  Madhu K.

  A type only - one that you create by using the primary key constraint clause.

  Try to categorize it at an abstract level, you could break up in:
  -single column
  -multi-column
  -column of substitution

  But I don't see the interest that the primary key does not behave differently or serve another or another purpose.

  It's like saying that there are 2 types of people in the world. Those who divides people into 2 types, and who are not...

• data transfer from one table to another and by generating a primary key

  Hello experts,
  
  Well, I have 2 paintings and I need to move columns in one of them.
  the problem is state that the primary key of the second table has to go in a column in the first table, and I generate a primary key in the first table as well. How to generate the primary key

  You can insert the value of key primary agent_id from agent table via before level trigger for insertion line. The agent_id value can be generated through a sequence.

  the trigger code can be as

  create sequence seq_agent;
  
  create or replace trigger trg_agent_id before insert
  on agent
  for each row
  declare
     v_agent_id number;
  Begin
     select seq_agent.nextval into v_agent_id from dual;
     :new.agent_id:= v_agent_id;
  End;
  

  So when will pull you insert tasks than this agent_id value will be added. And you will not get error

• Primary key with PHPmysql database question

  I know that the update of the primary key is a taboo subject, but I have a newsletter subscription form set up that works perfectly, but I can't understand how to create the primary key.  I tried to use the subscriber email address (because its unique, but when trying to add a function to update, I realize that the e-mail address may have to be updated.)

  My question is how do I get a primary key that works when I'm relying on a form variable to create the folder and did so no control over the assignment of one?

  Is it possible to have one assigned automatically when a Subscriber clicks on the submit button?

  This is why it is always a good idea to use surrogate keys. You can just have the database generates a unique id. In MySQL, I think that there is a column with the auto_increment attribute. If you then get this id after insert, php has functions for this (mysql_insert_id() I think).

• Question about primary key

  Hello

  What kind of primary key data should I user?
  
  I used the number in the past, but I've heard there are most efficient data type for this purpose
  
  Thank you

  BINARY_FLOAT and BINARY_DOUBLE types are designed to store floating-point numbers. If you generate synthetic primary keys using a sequence, you generate integers. It is absurd from a point of view to store data from integer to floating point fields of data modeling. And it is exceptionally dangerous if a value is rounded up unexpectedly (floating-point numbers lose precision for the bits from the right)

  You need to specify, for me, that means more "useful for indexing. The extent of the storage space is going, there may be some space savings using a BINARY_FLOAT and BINARY_DOUBLE types if you have very large values of primary key, but there will be a penalty of space for values generated by a more 'normal' sequence, i.e.

  SQL> create table x (
    2    col1 number,
    3    col2 binary_float,
    4    col3 binary_double
    5  );
  
  Table created.
  
  SQL> insert into x values( 1, 2, 3 );
  
  1 row created.
  
  SQL> select length(col1), length(col2), length(col3) from x;
  
  LENGTH(COL1) LENGTH(COL2) LENGTH(COL3)
  ------------ ------------ ------------
             1            8            8
  
  SQL> insert into x values (1e20, 1e20, 1e20 );
  
  1 row created.
  
  SQL> select length(col1), length(col2), length(col3) from x;
  
  LENGTH(COL1) LENGTH(COL2) LENGTH(COL3)
  ------------ ------------ ------------
             1            8            8
            21           15            8
  
  SQL> select * from x;
  
        COL1       COL2       COL3
  ---------- ---------- ----------
           1   2.0E+000   3.0E+000
  1.0000E+20   1.0E+020   1.0E+020
  

  So it takes 8 times the storage to store a 1 in a BINARY_FLOAT and BINARY_DOUBLE types it does to store in a column for the NUMBER. But it takes less space if you store values such as 1e20 (1 to 20 of 0). If you store values large enough to get the benefit of space, however, you're going to have rounded up questions that will result in the application not to function, as you can imagine is probably a much bigger problem than a bit of disk space wasted.

• Creation of primary keys, foreign keys and indexes

  Hello
  
  I created 60 new tables based on 60 existing tables.
  
  The 60 current tables are named FY11_ACC1, FY11_ACC2, FY11_SALES1, FY11_SALES2..., but all of the 60 tables start with FY11. I created the same structured tables but with names like FY12_ACC1, FY12_ACC2, FY12_SALES1, FY12_SALES2 FY12...
  
  I used the below SQL and generated SQL code.
  
  Select 'create table ' | Replace (table_name, 11, 12).
  ' in select * from '. table_name | "where 1 = 0'.
  from user_tables;
  
  But this did not generate the PRIMARY KEYS, FOREIGN KEYS and INDEXES. How can I automatically or with similar like SQL above? _
