How to add the new column in existing table to our desired location?

How to add the new column in existing table to our desired location?

For example, I have to add the new column 'course' before the salary column in the emp table.

I think the best way is to add the column at the end of the table and create a new view with the order of the columns...

Another option...

places the data into a temporary table and recreate the table with the correct order of the columns, and then insert data to the table from the temporary table


Add column (from table) in the desired position


CREATE TABLE temp_my_user LIKE)

SELECT * FROM password);

DROP TABLE password;



, first name VARCAHR2 (25)

, middleInitial VARCHAR2 (1)

(, name VARCHAR2 (25));

INSERT INTO password (userID, firstName, lastName)

(SELECT username

first name


OF temp_my_user);

DROP TABLE temp_user;

  • How to add the new column to a specific position


    My table looks like Fallows.

    How to get there.

    I tried like Fallows alter company table add company_location varchar2 (100) after company_short_name;

    but this query shows the error

    ORA-01735: invalid option of ALTER TABLE

    If the query I've tried is correct?

    Give me your suggestions.

    Thanks in advance.

    As long as you're on 11 GR 2 or lower, it will not work.

    There is no Clause "AFTER"in the alter table do not add column."

    You have the chance to use dbms_redefinition (when no interruption of service is possible) or manually create a new table with the columns in the order you need and then migrate the data and then drop the original and rename a new.

    In case you are already on 12 c, you have a chance to add the column to the end and then make visible columns and invisible status in the right order. This way your column will get to the position that you want it to be.

    Kind regards


  • How to add the new model feature with tables of another data schema?

    Hi all

    I am trying to add an entity data model to my request. The tables I need are on a schema that does NOT have a default schema of connection of the connection. So I go through the Wizard add new Entity Data Model, generation from database, but then when it comes time to choose your database objects, the only thing that shows is all that is on the default schema. How can I access stuff to another schema with an entity data model?

    (Tangentially: it is also a problem with the old Server Explorer simply itself - when adding an oracle db, I see the other schema object in the treeview control to break.) But when I right click the db and the new query, tables of other scheme become available to me here. "So it is less of a problem in the case of Server Explorer).

    I found this small excerpt to reach other patterns, but I couldn't make it work in the case of the ora db. Any suggestions?

    Thanks for the tips,

    Suppose that schema_a has granted privileges to schema_b on database belonged to schema_a objects by running the GRANT statements.
    You add a connection in Server Explorer using schema_b, and then add the schema_a in the "Filters" menu... ». Don't forget to click on
    the button of update in "Filters" dialog box and confirm schema_a illustrated with schema_b in the column 'value '.

    When to use EDM Wizard to create a database data model, choose the connection that you added by using Server Explorer
    schema_b. You will see the database of objects belonging to both schema_b and schema_a select and generate your data model. Schema_b
    should be able to use the database objects belonged to schema_a according to the privileges granted.

  • With CVI SQL Toolkit, how to add the new variable param column in a table.

    Dear all:

    I used the CVI Sql toolkit to create a database, but now I don't know how to add a new column to a table in variable param.

    I know, to add a column with the name of constant column could be down by below:

    DBImmediateSQL ((hdbc, "alter table table1 add column1 char [100]");

    But if Column1 is a param variablae how can I write the code? Please advise?  It will be appreciated if you could give me an example.

    Best regards!

    HI -.

    If you look at the parameters that you pass to the SQL function, you can see that the second parameter is a string constant. In your code, you can create an array of characters (string). You can then use sprintf to programmatically determine what will be the contents of this variable. In the function call, you can put the variable instead of the literal string, and you will have a customizable SQL statement.

    Hope this helps-

  • Effect with application ADF Go-live when I add the new column to the database.

    Hi all

    My already deployed ADF application and entry into service.
    I would add three columns of data.
    I worried that if I have does not add the new column and will redeploy again, it will have an effect at my request.

    Anyone here ever face with a kind of this problem

    As the General best practices. You do not direct operations on the ACTIVE database rather test the application in the test environment.

    on the other hand if your column is NOT NULL then it will affect your application otherwise no impact

  • Add the cluster to an existing table in oracle

    Is it possible to add the cluster of an existing table? For example...

    I have a table:

    CREATE TABLE table_name)

    t_id number PRIMARY KEY,

    t_name varchar2 (50));


    CLUSTER to CREATE my_cluster

    (c_id NUMBER) SIZE 100;

    Y at - it a command such as: ALTER TABLE t_name add CLUSTER my_cluster (t_id); or something like that?

    Because I want to table to look like this:

    CREATE TABLE table_name)

    t_id number PRIMARY KEY,

    t_name varchar2 (50))

    My_cluster (t_id) CLUSTER;

    And drop all the tables isn't really what I want to do.

    Thank you


    It is the reverse:

    A table can be stored as a segment of memory (the common way) or in a cluster.

    Will not be part of the table "in the cluster", but other parts outside.

    Please create a new table in the cluster and insert your data here.

    You get this error because your edit statement has an invalid syntax. In addition, you cannot partition a table that is not already configured for partitioning!

    You have to physically re-create the partitioned table in order to add new partitions to it.

  • Add the new column on BSE page


    I have a search page when I search on this page with a few criteria
    It shows a region of array type on what it shows all records in the db, that match this search criteria
    now, I want to add a column at the end of this table on the EBS page that displays
    and I want to show some value related to this record that is displayed on this table

    How can I get this value db linked to some folder basis

    and how do I set new column at the end of the table?


    Here are the steps you need to perform.
    1) go to the page with this region of the table. Click on this link page
    (2) check the name of the VO attached with the region of the table and click
    (3) in this page, you can see all of the attributes that are present in the original Version
    (4) if the new attribute you want to display exists in the vol. note his name.
    (5) create a new column in the region of the table through customization and attach this attribute VO with her as well as the view Instance.

    If this attribute does not exist in the original Version, then you must go for the extension of the VO.

    It could be useful!

  • How to add the 'new tab' button next to the last tab?... I use version 9.0.1. and they are missing and I can't find how to add.

    I got the new tab next to open tabs button, but with a recent update of Firefox, the tab button disappeared. Went through all the help points, but how do I add the new Help tab is not listed. The only way to open a new tab is manually using the buttons on windows/t or opening the file and choosing the new tab.


    It could be that he is hidden behind another icon. Please try this: right click on the empty space after the last tab and Customize.... With the mini window open, you can move the other toolbars and icons to check if the new tab button is hidden. You can also check inside the mini window customize the icon named new tab or click Restore Default Set that will be hopefully restore back. Please note that if nothing is uninstalled or disabled when you click on restore by default, you will have to redo all changes to manual/personal toolbar.
