• No sequences present in the comparison of two models of auto-increment columns and triggers

  Hi, I'm using Oracle SQL Developer Data Modeler version 4.0.3 and I get the same behavior described in the discussion 9876135.

  Y at - it an update on this issue?

  Thank you

  Hello

  No DOF preview is currently generated differences in properties on the auto-increment columns properties page.

  However, if you create a sequence with the relevant name (and the user as appropriate) in your physical model Oracle, then its properties will be used instead of the ones on the page Auto Increment, and in this case the DOF preview will include the DDL for changes in its properties, e.g.

  FALL OF SEQUENCE "TABLE_1_SEQ".

  ;

  CREATE SEQUENCES "TABLE_1_SEQ."

  START WITH 5

  INCREMENT OF 10

  ;

  If only the increment "by" is changed, an ALTER SEQUENCE will be generated:

  CHANGE THE SEQUENCE "TABLE_1_SEQ".

  INCREMENT OF 10

• Auto-increment for alreay column in existing table DB

  Hello

  We have a DB table with column of type Number. Table is already to have contained huge. Now, we want to have the auto-increment for this particular column.

  From now on, I created this table-based entity/view objects. Created attribute from entity sequence and update as follows.

  Create the GLOBAL_SEQ INCREMENT OF 1 SEQUENCE START with 1;

  Updated the expression of the attribute of the entity with logical next

  (new oracle.jbo.server.SequenceImpl ("GLOBAL_SEQ", object.getDBTransaction ()) .getSequenceNumber)

  When I tried to create a new line by using "Browser Oracle Business Component", the sequence fixed 0,1, 2... etc. But there are lines with these values in this column.

  But we want to create new line taking into account the maximum value of the column and the increment of 1.

  It would be great, if you can suggest an idea on this issue.

  Thank you

  MSR.

  You can leave to start the sequence with any number you like. For example, you can first make a max (id) of the table selection and the beginning of the sequence value max + 100...

• auto increment column restart

  I'm looking for a way to auto-increment column when I've found the solution here.
  BEST creation in Oracle auto-increment columns all the solutions I've found so far use a sequence. However when I remove the table and start the sequence restarts obviously in the last number that is used before.

  So in other words if I insert 5 records in the table I get the sequence 1-5, great! Then I delete the table and would like to raise again 1. obviously due to the method im using the sequence has been updated to obtain the next available number.

  How can I do an auto increment, which always starts from 1 in a table is a solid solution here?

  MySQL is a column of a simple table setting.

  Thanks in advance for any help you guys can provide.

  Here is the answer to my problem.

  UPDATE fvaljor

  SET FVALJOR_SEQ_NUM = ROWNUM

  WHERE FVALJOR_SEQ_NUM IS NULL

  Thank you Paul for trying to help.

  Is not to see that is a report on inserting records in a process already takes that awaits this column be numbered sequentially upwards by one. So I guess the business reason, it's simply that I have to do if I want to plug into this process.

  Thanks anyway, sorry if I wasn't clear.

• auto increment column

  Hello
  
  I have a total of 700 tables, each table has a column that must be incremented automatically.
  
  I am thinking to create distinct sequences and triggers for all tables.
  
  Is there a different approach that could be followed or sequence-trigger is the best option available.
  
  
  * This database has been migrated from MySQL where auto-increment option is available for columns contrary to oracle.
  
  Please notify.

  Salman Qureshi says:

  So I want to generate a trigger too.

  Still not clear what triggers have to do with the automatic generation of the column values. You will probably have to ask them about the details of trigegrs self-generation of values? If you just need automatic generation of values, sequences are what you need.

  Salman

  Using a trigger to fill the column ID with the value of the sequence, you don't have to worry about the application 'forget' to do. Some DBA or developer is once of sqlplus and forget to do. Placing him in a trigger, there is simply no way to properly fill the column in question.

• Management key id primary auto increment without using triggers

  Hi, we have a lot of table in our database with the installation of key ID primary autoincrement than they are in MySQL since we are in the process of migrating to Oracle of MySQL. Now in oracle I learned recently that this application requires the creation of a sequence and a trigger on the id for each table in the type field. We have tables of 30-40 in our scheme and we want to avoid the use of database triggers in our product, as the management of database is out of reach for our device software.
  What are my options to implement the auto increment id feature in oracle... aside from manually specifying the id in the code and it management in the code that would change many existing insert statements. Some info about our application environment: groovy grails, hibernate, oracle, support for mysql

  It is NOT auto-increment, you can avoid manual entry. When executing the INSERT statement, you must use the value of the sequence.

• mobile device of auto incremented field

  Hello
  my colleague needs to establish a mechanism in the mobile device (client lite oracle) where the primary field of a table is automatically incremented.
  
  According to the documentation in order to make that happen consistently, so that all customers can synchronize correctly without ambiguities, we have created a sequence
  through the MDW and attached to the publication. then with synchronization, this sequence has been downloaded to all customers and each has a specified window.
  We assume now that we must create the trigger that uses this sequence to provide the correct primary key field.
  
  lets say that the sequence is SYSTEM names. AUTOINCSEQUENCEA
  the table is named SYSTEM. TABLEA
  and the primary key we want auto incr is named ID.
  
  the trigger that we assume that should look like:
  
  CREATE A TRIGGER SYSTEM. TRIGGERTABLEA
  BEFORE INSERTING
  ON THE SYSTEM. TABLEA REFERENCING NEW AS OLD new AND old
  FOR EACH LINE
  BEGIN
  Select AUTOINCSEQUENCEA.nextval in: double new.ID;
  
  END;
  
  (1) but if I run this from the msql on the client machine (windows mobile device) returns an error "syntax". How can I create the trigger that I need that uses my sequence in order
  to appoint the new values in the primary key (auto incremented field?).
  (2) if I can't make it through a normal sql statement then how can I do?
  
  Thank you

  Finally got the work in the sample. See the example:

• Auto increment in a MySQL table programmatically

  Hello!

  I use the database connectivity Toolkit to perform various tasks with my MySQL database.

  I am successfully able to create tables, save data, display data, etc. - no problems.

  However, there is something I have to do when creating a table that left me speechless. I need a column in one of my paintings to be autoincremented (Ie, no duplicates).

  It is possible to define this through a program such as MySQL Workbench, but it is not possible to do through LabVIEW.

  Is it possible through LabVIEW? And if so, how? Maybe it's a setting I'm missing or should I send a query using one of the functions in the box tools?

  If you need more info just ask.

  Thanks in advance.

  I have no specific experience with MySQL, but as a general rule, when inserting into a table with auto-increment columns, the insert query does NOT include this column, its value is determined automatically.

  If you are talking about creating a table with an auto-inc column, then I suppose that you use the create table VI. If you open the VI, you will see that it simply creates a SQL query. Search the relevant SQL syntax to do an auto-inc column and then create a copy of the VI and change it to you to specify the column using this syntax.

• An error explanation & missing in docs concerning Auto Increment / identity

  HI Data Modeling Team, Hello fellow readers,.
  
  could you explain the meaning of the option
  'Properties of the column' - 'General' - 'Identity' (side), that I don't see a logical difference between these two.
  
  In addition, the meaning of these fields is left in the docs under
  http://docs.Oracle.com/CD/E18464_01/ doc.30 e15802.pdf 'properties of the column 3.8' - 'General' (page 75)

  Hi Laurent,.

  You can have only one column of identity for the table. We do not limit the number of auto-increment columns.

• Update field of auto-increment using ASP.

  I use Dreamweaver 3 and created dynamic arrays using the tools ASP. I met a wall:

  When you create a form to a form, how to configure the form to update an Auto-Increment field in Access?

  I have what I think is a good book on Dreamweaver, but this feature is not discussed. If I omit the field of

  the form, he leaves the null field and I get a database error, as I expect.

  Any help or documentation links will be appreciated.

  Joe

  As others have said, the database must manage this area and it shouldn't appear on the form on the page in code that performs the actual insertion or update.

  Do you a little differently depending on whether you use the wizard insert or create the form by hand and then apply the server behavior insert.

  If you use the wizard when you select the fields in the form, make sure that you click the auto increment field, and then click the icon 'less', this it will remove the form and it will not appear in the code generated automatically, leaving MS Access free to manipulate himself.

  If you create the form by hand, do not include a form for the field to auto-increment element, then when you apply the Insert behavior it will not appear in the code generated automatically, leaving MS Access free to deal with himself.
