Help me in creating a trigger Insert and Update Options

Hello

Please help me in creating a trigger.

My requirement is that, after insert or update on a Table, I want to launch an event.

I have started this way, but does not know how to fully implement it.

I have a dept table

CREATE TRIGGER DepartmentTrigger
INSERT AFTER on Dept
BEGIN
INSERT INTO mytable VALUES("123","Kiran");
END DepartmentTrigger;

Please tell me how I can put the update option also.

Thanks in advance.

Please tell me how I can put the update option also.

Add "or update". ;-)

Here are a few suggestions, but you definitely need to refer to the manual page that suggested the previous poster.

CREATE OR REPLACE the TRIGGER DepartmentTrigger
AFTER INSERT or Update ON Dept
BEGIN
INSERT INTO mytable VALUES(:new.) Dept 'DEPT ADDED OR CHANGED');
END DepartmentTrigger;

The "or replace" means that you can replace the shutter button as you develop without having to type in a drop statement each time. Just change and reissue your script over and over again until you get it right.

The addition of "update or" or "Or remove" fact the trigger too much fire for these events. Note, you peut want separate triggers in different scripts and with different names for each event. You must decide whether your design is really the same thing either an insert or an update.

: new. Dept, this is how you should refer to the vale has changed the Dept column (: old.) Dept is the previous value). I changed the double quotes in the string in the clause VALUES of apostrophes.

Hi Paavo,

most of the steps can be made in one or other way

-create sequence for the id column

-create table

-create indexes for the id column pk

If you want to start in the logic model and you don't want to have the ID column in the logic model and select 'Create the surrogate key' checkbox in the dialog entity - you will get an identity column in the relational model and the version of database and settings in ' preferences > Data Modeler > model > physics > Oracle "you can set the sequence generation and the trigger for taking in load.

You can add the same set of columns in all tables with the transformation script 'model of Table... ».

You want to capture update dates, with trigger on a view to refresh quickly materialized. But trigger on MV consider inserting and updates are inserts only.

I create the structure of the table like that.
create table test1 (a primary key, b (2) char number, date c, d varchar2 (10), date of e);
create table test2 (number of ab, cd (2) tank, date of the ef, gh varchar2 (10), date of the ij, kl varchar2 (100));
Create materialized view log on test1;
create materialized view fast refresh test1_v on commit in select * from test1;
I have create a trigger of the sample
CREATE OR REPLACE TRIGGER test1_trig
AFTER INSERT OR UPDATE OR DELETE
ON test1_v
FOR EACH LINE
DECLARE
lr_test2 test2% ROWTYPE;
lv_error VARCHAR2 (4000);
BEGIN
lr_test2. AB: =: NEW.a;
lr_test2. CD: =: NEW.b;
lr_test2. GH: =: NEW.d;

THEN
lr_test2. EF: = SYSDATE;
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'INSERT ';
INSERT INTO test2

THEN
lr_test2.IJ: = SYSDATE;
lr_test2.KL: = 'UPDATE ';

END test1_trig;

So, if check you my code,.
When I insert EF = SYSDATE, IJ = SYSDATE.
Update EF is not changed, IJ = SYSDATE.
So I like to capture their insertion and update dates.
But if updates or insert arrives on the materialized table. The trigger themselves as an INSERT only.
So how do you capture the updates?

I use the statemnet with out merger with performance and also able to capture the update dates.

CREATE OR REPLACE TRIGGER test1_trig_merge

FOR EACH LINE

DECLARE

lr_test2 test2% ROWTYPE;

THEN

AB = WHERE: old.a;

ELSIF INSERTION

THEN

MERGE INTO test2 one

WE (ab =: new.a)

WHEN MATCHED

THEN

UPDATE the VALUE ab =: NEW.a.

CD =: NEW.b,

Mr President

Jdev worm is 12.2.1

How to modify and update a line later was inserted and updated in the doDML() method?

I added two rows in my table a method of action-listener in bean managed and secondly with operation doDML() as below.

Now the problem is that when later I change the quantity and price of the first line isn't updated but second row, because I used the command

 <af:button actionListener="#{bindings.Commit.execute}" text="Commit"

This button update the first line added by bean managed, but the second row remains unchanged.

Please help how to update the two lines with the same button or something else.

Concerning

DML_UPDATE will call only if there is some change data attributes.

I guess that the update statement is false because vid looks like a primary key for the table, then, how update you the primary key of the update statement and how the update condition statement where the vid = '0'

I assume the update statement should look like:

  private void updateSecondRowInDatabase(Object value1, Object value2, Object value3, Object value4)
  {
    PreparedStatement stat = null;
    try
    {
      String sql =
        "update vdet set lineitem='" + value2 + "',DEBITST='" + value3 + "', AMOUNT='" + value4 +
        "' where VID='" + value1 + "'";
      System.out.println("sql= " + sql);
      stat = getDBTransaction().createPreparedStatement(sql, 1);
      stat.executeUpdate();
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
    finally
    {
      try
      {
        stat.close();
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }
    }
  }

Add error causing senior in 4.2.1 when inserting and updating same time

Hi all
I have problems with the top to add a line in a table.
There is already a thread here on how to add the line above in table form in version 4.0.
We have recently upgraded to version 4.2.1 Apex.
Since then we have question while inserting a new line and update an existing line at the same time, and then click Save button causing the error below:
Current version of the data in the database has changed since the user initiated the update process. version of current line identifier = "xxxxxx" line application version identifier = "xxxxxx".
But insert a new record and update an existing record works well separately with an error.

Here's the code to add the line at the top of page header HTML
```
<script language="javascript" type="text/javascript">
function addRowTop()
{
apex.widget.tabular.addRow();
apex.jQuery(apex.widget.tabular.gTabForm).find(".highlight-row").last()
.insertBefore(apex.jQuery(apex.widget.tabular.gTabForm).
find(".highlight-row").first());
}
</script>
```
If I use by default addRow so absolutely no problem to insert and update at the same time.
Here is the example of work in the workspace apex.
Looks like a bug to me.
Can any of the Oracle team please see this and let us know if it needs a patch.
Thank you
REDA

Not sure that I consider this a bug since you are somehow hacking the default functionality of the APEX. Maybe you could add a feature request 'Add Top line' to https://apex.oracle.com/vote

It seems that you hit some enhancments to safety that have been made to the tabular forms. You should be able to work around it by putting the new lines to the bottom of the form before submitting the page.

Create a dynamic action based on the click of the submit button.

Event: click on

Selection type: button

Button: SUBMIT (Submit)

Condition: - no requirement.

Add real action to run the JavaScript Code:

Action: run the JavaScript Code

Fire when the result of the event is: true

Fire on Page load: [disabled]

Code:
```
apex.jQuery(apex.widget.tabular.gTabForm).find("input[value=''][name='frowid']").closest(".highlight-row")
 .insertAfter(apex.jQuery(apex.widget.tabular.gTabForm).find(".highlight-row").last());
```
Add a real action to send the page:

INSERT and UPDATE audit generating more lines expected in $ AUD
Environment:

Oracle 11.2.0.3 EE on Solaris

I had a request for verification of the INSERT and UPDATE on the activities of all the tables in a particular schema. It was in anticipation of a request that will live and the owner wanted to see a 'typical' of some test users activity.

Here are the steps I took:
```
alter system set audit_trail=DB_EXTENDED scope=spfile;

Bounce the instance

audit INSERT table, UPDATE table by USERX;
```
I also "audit_sys_operations = TRUE' so I know I'll take some SYS audit data in $ AUD as well, but I can ask around those."

My question is that I see several connections from the application server with "LOGIN" and "LOGOUT" actions and I don't know why they are appearing in the table of AUD $.

Is it because I have auditing enabled for inserts and updates on all THE tables for USERX and opening operations and logoff do I/O in tables that are not owned by USERX under logon logoff procedure?

I'm a newbie audit and the docs I read not answered this question.

I just found an article on the value of 'SESSION_REC' of ACTION_NAME and I need to change my check to "by access. I'll change that and see what happens, but it shouldn't change my question.

Thanks much for any help!

Hello
```
I have the SYS activities audited but I never said anything about the session auditing for this particular user.
```
"audit session;" check all successful and failed connections to and disconnections of the database, regardless of the user, by session
```
Is there a way to confirm what has been turned on for auditing?
```
You can check with the following query

Select * from dba_stmt_audit_opts;
Select * from dba_priv_audit_opts;

Combining insert and update to a form?

Hello
I am a developer web amateur who is new to dynamic Web sites, php and dreamweaver. I am currently working on a project that uses many forms to send data to a database.
Data that are inserted must also be available to update if necessary. so I need currently 2 versions of each form 1 to insert and the other for the update.
Is it possible to use a single form for insert and update, instead of using 2 forms 1 for each function. This would help reduce the level of duplication on the site.
If so is anyway to do this in Dreamweaver? or could someone point me to an example of how this can be achieved.
Thank you all

Thanks for the information, disappointing that Dreamweaver cannot handle it, but at least I know where I am...

Insert and update server behaviors in the same form

I have a php form that is inserted into a table and then update another table. I have the form of inserting the record first and then I want to update the other table. I'm starting to learn and understand PHP, but I don't know how to have the update function to run after that it inserts the records. I guess that's something like if you insert this disc, then update this record and then go to the redirect page. I know this goes to redirect page after it inserts the record, but I don't know how to tell him not to go to the $insertGoTo. I want him to run the following update function and then go to the $insertGoTo and not the $updateGoTo. Thanks in advance for any help.

PHP code is executed from top down and is controlled by the conditional statements ('if' blocks). To achieve what you want, you need to combine the conditional statements that control the insert and update server behaviors and to move the redirect to the end of the code. Amend as follows:

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
  $insertSQL = sprintf("INSERT INTO employee (CompId, empfirstname, empmiddleint, emplastname, EmpType, EmpStatus) VALUES (%s, %s, %s, %s, %s, %s)",
                       GetSQLValueString($_POST['CompId'], "int"),
                       GetSQLValueString($_POST['empfirstname'], "text"),
                       GetSQLValueString($_POST['empmiddleint'], "text"),
                       GetSQLValueString($_POST['emplastname'], "text"),
                       GetSQLValueString($_POST['EmpType'], "text"),
                       GetSQLValueString($_POST['EmpStatus'], "text"));
  mysql_select_db($database_dotweb, $dotweb);
  $Result1 = mysql_query($insertSQL, $dotweb) or die(mysql_error());

  $updateSQL = sprintf("UPDATE company SET CompanyType=%s WHERE CompId=%s",
                       GetSQLValueString($_POST['CompanyType'], "text"),
                       GetSQLValueString($_POST['CompId'], "int"));
  mysql_select_db($database_dotweb, $dotweb);
  $Result1 = mysql_query($updateSQL, $dotweb) or die(mysql_error());  

  $insertGoTo = "Roster.php?CompId=" . $_POST['CompId'] . "";

  if (isset($_SERVER['QUERY_STRING'])) {

Do you mean by using subqueries?

Something like
```
insert into whatever
  ...select statement

 update whatever
    set (column, column) = (select column, column ...)
```
There is a lot of information on this topic in the online documentation

If you are user of Jack and sending it to the db in plaintext in
the query, and then people can use techniques of SQL injection basically destroy
your database:

So, Yes, it's a pretty serious problem.

This trigger is in the database or in Jdeveloper... If it s in Jdeveloper how can I do this?
Thank you.
User,

You can create the trigger in the database or write code in the class of java feature object to do.

You can have a reading in the developer's Guide to the ADF for forms/4GL developers 6.6.3.8 section to know more about the trigger of the DB. 9.4.1.2 section talking about how to do java EO class if you prefer this method.

Create a trigger instead of update several tables in a view

I am trying to create a trigger that updates instead of to day joined several tables in a view, but I can't get my trigger to work. The create view command was as follows:

AS
SELECT MAP_INDEX.mi_prinx,
       index_type_id,
       original_map_publication_id,
       original_map_sheet_number_id,
       name_of_feature,
       geog_coordinates_id,
       GEOG_COORDINATES.mi_prinx AS "mi_prinx_polygon",
       GEOG_COORDINATES.geographical_coordinates,
       GEOG_COORDINATES.mapinfo_style_row
 FROM MAP_INDEX
  JOIN GEOG_COORDINATES
   ON geog_coordinates_id=GEOG_COORDINATES.mi_prinx;

The view above connects a polygon table to the table of function names which means that a polygon appears several times in a view, even though one version of the polygon exists in the base table. This means the direct update of view cannot take place, since 1 polygon can appear multiple times in a view. The two original base tables and their columns names are:

MAP_INDEX
---------
MI_PRINX
INDEX_TYPE_ID
ORIGINAL_MAP_PUBLICATION_ID
ORIGINAL_MAP_SHEET_NUMBER_ID
NAME_OF_FEATURE
MAPINFO_STYLE_ROW
GEOGRAPHICAL_COORDINATES
GEOG_COORDINATES_ID

GEOG_COORDINATES
----------------
MI_PRINX
GEOGRAPHICAL_COORDINATES
MAPINFO_STYLE_ROW

Relax, I created was as follows:

CREATE OR REPLACE TRIGGER TRIG_VIEW_MI_JOIN_GC
   INSTEAD OF UPDATE ON VIEW_MI_JOIN_GC
      REFERENCING NEW AS NEW
 FOR EACH ROW
BEGIN
 UPDATE MAP_INDEX
  SET mi_prinx = :NEW.mi_prinx,
      index_type_id = :NEW.index_type_id,
      original_map_publication_id = :NEW.original_map_publication_id,
      original_map_sheet_number_id = :NEW.original_map_sheet_number_id,
      name_of_feature = :NEW.name_of_feature,
      mapinfo_style_row = :NEW.mapinfo_style_row,
      geographical_coordinates = :NEW.geographical_coordinates,
      geog_coordinates_id = :NEW.geog_coordinates_id
   WHERE geog_coordinates_id = :OLD.geog_coordinates_id;
 UPDATE GEOG_COORDINATES
  SET mi_prinx = :NEW.mi_prinx,
      geographical_coordinates = :NEW.geographical_coordinates,
      mapinfo_style_row = :NEW.mapinfo_style_row
   WHERE mi_prinx = :OLD.mi_prinx;
END;
/

The idea is that when I draw a new polygon in MapInfo and assign him a revised number geog_coordinates_id and the number of mi_prinx_polygon, which are the same, once I have save the view as then it updates the underlying tables. Geographical_coordinates and mapinfo_style_row of map_index table columns are columns with ancient polygon data which while not having currently new data inserted into them, are required for the previous data they contain. These data are currently being added to the geog_coordinates table with other scripts. The idea is that all the data is then read using a view and updates made to the view, triggering instead of relaxing, so data are not duplicated but still visible as if it were.

When I created first the relaxation above in SQLdeveloper it seems to run constantly. Then my computer crashed, not related to this work, and I lost session because I did not commit it. I was not ready to commit it because I believe that something is wrong.

I am in the trigger syntax correctly and I go about it in the right way? I want to only update the rows that have changed, that's why I was using: NEWS and: OLD.

Kind regards

Tim

I modified my script a little because there were a few errors. for example. start and old as old and view name typo

Something like this->
