The sequence trigger

Hello
I want to set up a trigger that fires when a sequence is incremented.

Select double userid_seq.nextval;

would be the trigger.

Is it possible to define a trigger fires during a sequence is incremented?

Any help or pointers are appreciated.

Thank you.
Shannon

As says cd, set the function with the line beginning with PRAGMA:

CREATE OR REPLACE FUNCTION USERID_SEQUENCE
RETURN NUMBER AS
PRAGMA AUTONOMOUS_TRANSACTION;
  CURSOR cr IS
    SELECT USERID_SEQ.NEXTVAL
      FROM DUAL;
  nId NUMBER;
BEGIN
  OPEN cr;
  FETCh cr INTO nId;
  CLOSE cr;
  INSERT INTO SESSIONS (ID,TIME_STAMP) VALUES (nId,SYSDATE);
  COMMIT;
  RETURN nId;
END;

But be aware that the insert always takes place, even if you do not use the sequence value selected for anything whatsoever.

TRIGGER - how to auto fill a column with the sequence
Hello

I have a table that contains information about the customers... I have bound him to a form of the APEX so that when a user enter information through a form he generates a sequence/trigger number and saves it in the column (named tracking_NO)... I use this tracking_no as key for monitoring purposes.

My problem is that when the admin will post information from MS access to Oracle, it generates automatically a number for my column 'tracking_No '... Please advice how to use the same trigger Auto Fill a column (tracking_no) when the value is zero.

Here's my trigger

CREATE OR REPLACE TRIGGER B.T_CUSTOMER_TRG

REFERRING AGAIN AS NINE OLD AND OLD
FOR EACH LINE

If: NEW. "' TRACKING_NO ' is null then
Select T_CUSTOMER_SEQ.nextval in: NEW. "' TRACKING_NO ' from dual;
end if;
end;

I really think this is a bug coding causing this duplication.

You wrote trigger on the table of the student. So in the trigger, only the columns of this table must be offered for example: NEW.zip.

Since zip_id is not part of this table, the: NEW.zip_id must always generate the error.

insert into student_v (zip) values('111');

In the above statement, you can only provide the value for the column zip but not zip_id. Therefore, the: NEW.zip_id is not available in the trigger. Must extract this value in the sequence after it is created.

for example

create the test of the order;

INSERT INTO postal code

(zip,

zip_ID,

created_by,

CREATED_DATE,

Modified_By,

MODIFIED_DATE)

VALUES (: NEW.zip,)

test.nextval,

NULL,

USER,

SYSDATE,

USER,

SYSDATE);

Insert data. Select the sequence ID, but popuate even value for two different columns

What is the way to apply the sequence ATG?
What is the way to apply the sequence ATG?
for example, if I want to order numbers to increment in order 1,2,3,4,... What is the way to do it?
Best way to generate an ID field is by the use of an IDGenerator. It is not guaranteed to generate numbers which are contiguous.

To get numbered contiguously order numbers, I guess you could add another field to the order and have a database trigger that will select the next value in a sequence in the database itself. In the application could get complicated if there are multiple instances ATG running the same application.

Number of the sequence in the form of the ADF.
Hi all

I have a table with ID as primary key and have a sequence created for the primary key and have a trigger to generate the sequence number when the record is inserted in the table.
How can I map this sequence in the ADF so when inserting record in the form I can skip the ID column.

Kind regards

Hi all

I need help on this trigger,

It's the scripts of the tables.
CREATE TABLE TEST (ID NUMBER NULL, NAME VARCHAR2 (20 BYTES) NULL, TYPE NULL VARCHAR2 (20 BYTES), CONSTRAINT TEST_PK PRIMARY KEY (ID));
Insert in the TEST
(ID, NAME, TYPE)
Values
(1, "caroline", "student");
COMMIT;

CREATE THE TEMP TABLE (NULL NUMBER ID, NAME VARCHAR2 (20 BYTES) NULL, NULL OF TYPE VARCHAR2 (20 BYTES), TST_ID NUMBER NULL, CONSTRAINT TEST_PKD PRIMARY KEY (ID), KEY FOREIGN (TST_ID) (ID) REFERENCES TEST);

create sequences tst_id

There are two tables.
Test table (first picture). This is a table with the original data. Now, it's so that when there is an update on this table, the record that is updated should be written to the temp(second table) table in the initial state.

For example.
the record in the table test is updated
ID NAME TYPE TST_ID
1 ColArt student 1

Temp table is inserted recording that had updates,

ID NAME TYPE TST_ID
1 student caroline 1

you want to store the original values, right?
you did a SELECT INSERT - instead of INSERT VALUES

With the help of the sequence
Hello world

Is it possible that we can assign/join a sequence on the column of a table, in fact, the requirement is that I table, in which a third person is going to be inserting data and they want join column where this sequence is expected to generate an automatic numbering after inserting each record a sequence.

For as far as I know we can use the sequence through a form to insert the auto numbers.

Any help will be appreciated.

Thanks in advance

no difference in performance on the sequence of release compared to insert third
Hello
I am perhaps concerned about how to proceed,

but y at - it overhead by using a trigger to store the unique value for a column of a sequence.
the other option is to use the seq.netval in the insert or merge statement.

It's a few million records per day.
Since I have an Oracle RAC cluster on 9i, I guess I must have noordered for reasonable performance.

To quote it's a batch of loading the several tables with unique value on several tables using insert and merge.

Thank you
Goo
Yes, there is a difference. With the help of a trigger will be significantly slower that put the sequence.nextval in your INSERT statement (assuming you have no other reason to have a trigger) because you'll avoid SQL 1 million to changes in context of PL/SQL. It would probably be a substantial fraction of the cost of him actually insert the data. Of course, if your insert statement performance is dominated by the cost of select the million lines, the impact of the trigger would be proportionately less.

As an illustration, a quick test on my machine indicates a difference factor 7. I can insert 1 million rows in 6.63 seconds
```
SQL> create table foo( col1 number );

Table created.

SQL> create sequence foo_seq cache 10000;

Sequence created.

SQL> set timing on;
SQL> insert into foo
  2  select foo_seq.nextval
  3    from dual
  4   connect by level <= 1000000;

1000000 rows created.

Elapsed: 00:00:06.63
```
But if I add a trigger, it takes 47,63 seconds
```
SQL> create trigger foo_trg
  2    before insert on foo
  3    for each row
  4  begin
  5    :new.col1 := foo_seq.nextval;
  6  end;
  7  /

Trigger created.

Elapsed: 00:00:00.70
SQL> truncate table foo;

Table truncated.

Elapsed: 00:00:01.35
SQL> insert into foo
  2    select 1
  3      from dual
  4    connect by level <= 1000000;

1000000 rows created.

Elapsed: 00:00:47.63
```
47,63 / 6.63 is slightly less than 7.2

How can I change the sequence of displayed in Thunderbird mail accounts?

I need to set up a laptop computer to take on the go. How can I change the sequence (list) of e-mail accounts in the vertical pane to match my office?

Install this add-on.
https://addons.Mozilla.org/en-us/Thunderbird/addon/manually-sort-folders/

They showed me a way to do a massive bowl of spam, but I don't remember the keys and the sequence to do.

I recently had installed Thunderbird and more 10,000 e-mails were transferred. They showed me a way that if I press Ctrl and another sequence of keys, I could scroll through many emails and send them to 'trash' collectively, instead of having to delete each message individually. I don't remember the keys and the sequence to do.

CTRL + a (for 'all') will select all of the visible items.

How to change the sequence of films in iMovie Theater

By exporting iMovie projects in iMovie Theater, the sequence of films is determined by the time of download. How to change the sequence of films in iMovie Theater list?

HI, breeaz,

I have not found a way to change the sequence of films shown in the movie screen.

If you access your movies in the Finder folder, then Ctrl-click on the folder of the theatre, you will find your movies to the poster

in the alphabetical order in archival records. I was not able to manually rearrange it. They can be rearranged in some categories, through the view menu item at the top of the screen and the changes applied to the entire window, but it was not carrying at the display of iMovie. In General, I'd like to make changes to the structure of iMovie in the finder. It can cause serious problems.

Best,

Rich

This point cannot be shared while it's still multimedia reference on the camera. This message prevents the sharing of file in the sequence

This message keeps me from sharing file in the sequence. I'm done with the movie and want to print on DVD

Your camera with multimedia files that it is connected to your Mac?

How can I change the sequence exported to iMovie?

When I finished making the video and it has exported, some errors found only. How can I change the sequence exported in the application iMovie editing new, mainly texts?

Just open the project that you exported from iMovie, make the changes necessary, then export again. (Sod / Murphy's law always ensures that errors found only after export)
