Trigger for INSERTION OF THE COLUMN exists?

Hello Experts

I just wonder that relaxation of the COLUMN INSERT exists as UPDATE OF THE COLUMN? If so, it seems illogical to use insert the trigger. Because can not insert for a spesific columns that we effect the registration worldwide, right line?

Thank you

There is NO such syntax as a review of the language PL/SQL doc will show you

CREATE TRIGGER statement

dml_event_clause

Specifies the trigger instructions for simple_dml_trigger or compound_dml_trigger . The database enables the trigger in the existing user transaction.

DELETE

Causes the database to activate every time a DELETE statement drops a line to table or table on which view is defined.

INSERT

Causes the database to activate every time a INSERT statement adds a line to table or table on which view is defined.

UPDATE [columns [, column]]

Causes the database to activate every time a UPDATE statement changes a value in a specified column. Default: the current database the trigger every time that a UPDATE statement changes a value in a column of table or table on which view is defined.

If you specify a column , then you cannot change its value in the body of the trigger.

  • trigger for insertion of a table to another table

    Hello again,

    I tried to write a trigger after insert or update will happen in table 1, it will move some values in another table, as shown below:

    Create or replace trigger Insert_Amount_Credit after insert or update on Reciept_Voucher

    Referencing NEW AS NEW OLD OLD FOR EACH LINE AS
    Start

    Insert into customer_Details (Transaction_Date, client_name, Description, credit) values (new. Rec_Date, new. Client_name, CONCAT (' receipt number:', again.) Rec_ID), new. Amount);

    End;

    /

    The trigger was created but with compilation error... and my question is:

    1. How do I write the code above in the best way?

    2. How can I enough the other table with a table concatenated as what I was trying to make above?

    any idea?

    Something like that?

  • How to fill out the list for inserts in the procedure?

    I want to populate a list for a string of inserts.  All pads are the same except each iteration will change by this list.

    inserting into table X (A, B) values (1,2);

    In my case, I want to change the value each time column 2.

    So, something like this:

    DECLARE

    v_species varchar2 (10);

    CURSOR spec_code_cur is

    This is an example of my list... I need to get into the cursor.  I thought to use the double, but it did not work.  They do not live in any table yet, so I can't question.

    ACGL,

    AGCR,

    ALINT,

    ARTR2,

    IDEC,

    CEVEV4

    BEGIN

    FOR v_species in spec_code_cur

    values ('450DB4460A7449B0E0440003BA9ECAD1',v_species, 'ON');

    The desired output would be for inserts run as:

  • Photosmart 7520: 7520 Photosmart black too big HP 564 black cartridge for insertion in the cartridge tray

    My Photosmart HP 7520 has 2 black cartridges.  One is narrow with the same width as the color cartridges and the other is larger and fits OK into its slot on the far right.  Close cartridge is supposed to be inserted into the slot on the left.  I bought 3 new cartridges of 564 black but it's widest 564 black.  How to find the narrow black cartridge?

    J_A_A

    564 cartridges are labeled with icons for identifications. Black regular has a Pentagon on it and black Photo has a 'Butterfly' icon (and image of the camera on the package). I think that you're looking for is the photo in the black.

    BTW, regular 564 also has a narrow black (standard load) and more wide (XL), so make sure match the icon, not the size.

  • Insert/update the column with the clob data type

    Hi all

    ORCL Version: 11g.

    I have a table with the clob data type.

    Test12

    (col1 clob);

    I'm trying to insert/update to update the column with more than 4000 characters.

    But due to the limitation of tank 4000, I could not Insert/Update.

    Need your help in resolving this issue.

    THX

    Rod.

    The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

    Here is an example that shows how to insert it, I found...

    Otherwise, here is a way 'dirty' to do.

    insert into your_table (COLA, COLB)

    values

    (PRIMARY_KEY, PART 1 OF DATA)

    ;

    Update your_table

    Define COLB = COLB | PART 2 OF BIG DATA

    where COLA = PRIMARY_KEY;

    Update your_table

    Define COLB = COLB | PART 3 OF BIG DATA

    where COLA = PRIMARY_KEY;

    .. and so on...

    I don't know that I personally recommend the second style...  But he could do the job.

  • Trigger for insertion post

    Hi all

    I want to update a column on the newly inserted row. So I wrote a trigger on the table, but it does not update the current row. For example

    If there were two rows of the table with the same criteria, two were created a minute ago, trigger will update the two lines but not the current.

    No idea how to upgrade the new line. I think that AFTER insertion, row trigger should be available in the table and must be updated, but is not.

    Thank you

  • Record is not inserted into the transparent Table Forms 10g

    Hi all

    I have the built in 10g (10.1.2.0.2) form.

    Basically, the form has 2 blocks.
    1 block with a single element, where we enter a value and press on enter (this place you block2 and run the query).
    Block 2 (tabular) will get the records. This block2 have now 3 columns (caseid, userid, date).

    Now when I insert a new record, I just need to get the caseid only. And username and date must be filled in automatically.
    I can fill fields username and the DATE.
    And when I enter a value element of the block 2 caseid and then Control + S(to insert the record and Save the transaction),.
    I get the message saying FRM-40400: transactions: 1 applied and saved records.
    But when I ask again for the same thing, I do not have is the record inserted into the table.
    Why is this happening?

    Insert the value of Column1 in trg2 where Column3 = "yyy".

    After giving the conditions on mapping, the where conditions become clubed with and I get a different value to what is excluded. As the same way, I have the same scenario for most of the columns in my target table. Suggest me how do.

    Thanks in advance.

    Hello

    to do everything in a single interface without performance issue you could do a join like this

    Source.col2 = source2.src1 or Source.col2 = Source2.src2

    This mapping and

    Target.trg1

    CASE WHEN Source.col2 = Source2.src1 THEN

    Target.TRG2

  • Add the value of the column to MRU

    Hello
    I'm sure there is a simple solution to what I see, sorry if this is the case.

    I would add column values to the update of the Apex Multi line. These values are the elements on the page, apart from the form of paintings, but common to all lines updated.

    In other words, offer will save values in tabular form with the standard MRU and then a process of "trigger as" should add these additional values.

    How can I do this without having to create a custom MRU?

    Thank you
    Marc

    Hello

    I see two methods that may work.

    First of all, you say "trigger like' - why not use a real trigger for do? The values in your page items would be available using nv('Pnn_ITEMNAME) in the trigger code.

    Alternatively, you can include the column in the form of your table, and then use javascript to hide. Then, again using javascript, you could update the field until the submission process is triggered by the button. The button should call this function and then use doSubmit() to submit the page.
