Need to create a trigger that generates multiple rows in another table

{size: 12} Hello

I use Oracle9i (9.2.0.4.0)

My problem is:
I need to create a trigger that create different in the other table lines when someone will introduce a new line in the first table.

For this, I use the table 4:

1. first one where you want the trigger.
2. a second just to take information.
3. a third to make a trip meter.
4. the fourth is the table where I want to create new lines. {size}

Here is a summary of these 4 tables:

{color: blue} Table 1
STOJOU
Number ¿Nulo? Tipo
STOFCY_0 NOT NULL VARCHAR2 (9)
ITMREF_0 NOT NULL VARCHAR2 (60)
LOT_0 NOT NULL VARCHAR2 (45)
VCRTYP_0 NOT NULL NUMBER (3)
VCRNUM_0 NOT NULL VARCHAR2 (45)
VCRLIN_0 NOT NULL NUMBER (10)
QTYSTU_0 NOT NULL NUMBER
NUMVCR_0 NOT NULL VARCHAR2 (45) {color}

{color: blue} Table 2
ITMMASTER
Number ¿Nulo? Tipo
ITMREF_0 NOT NULL VARCHAR2 (60)
ZCOEFI_0 NOT NULL NUMBER {color}

{color: blue} Table 3
ZCTUART;
Number ¿Nulo? Tipo
CTUART_0 NOT NULL NUMBER (10)
CTUDATE_0 NON NULL DATE {color}

{color: blue} Table 4
ZUART
Number ¿Nulo? Tipo
ZUARTDM_0 NOT NULL VARCHAR2 (102)
STOFCY_0 NOT NULL VARCHAR2 (9)
STOCOU_0 NOT NULL NUMBER
ITMREF_0 NOT NULL VARCHAR2 (60)
LOT_0 NOT NULL VARCHAR2 (45)
CREDAT_0 NOT NULL DATE
QTYSTU_0 NOT NULL NUMBER
STA_0 NOT NULL VARCHAR2 (3)
VCRLIN_0 NOT NULL NUMBER (10)
VCRNUM_0 NOT NULL VARCHAR2 (45)
VCRTYP_0 NOT NULL NUMBER (3) {color}

I do this trigger:

CREATE OR REPLACE TRIGGER CREA_REGISTROS_TRAZA
AFTER INSERT ON STOJOU
FOR EACH ROW
DECLARE
   n INTEGER;
   ct NUMBER;
   fecha_actual VARCHAR2;
   fecha_old VARCHAR2;
   codigo_dm VARCHAR2;
BEGIN
   fecha_actual := TO_CHAR(SYSDATE, 'DD/MM/YYYY');
   -- SELECT TO_CHAR(sysdate, 'DD/MM/YYYY') INTO fecha_actual FROM DUAL;
   SELECT TRUNC((STOJOU.QTYSTU_0/ITMMASTER.ZCOEFI_0),0) INTO n FROM STOJOU INNER JOIN ITMMASTER ON STOJOU.ITMREF = ITMMASTER.ITMREF;
      FOR i IN 1 .. n
   LOOP
      SELECT CTUART_0,TO_CHAR(CTUDAT_0, 'DD/MM/YYYY') INTO ct,fecha_old FROM ZCTUART;
      IF fecha_old <> fecha_actual THEN
        ct := 0;
      END IF;
      ct := ct + 1;
      INSERT INTO ZCTUART
        (CTUART_0,CTUDAT_0)
      VALUES
        (ct,SYSDATE);
      codigo_dm := SUBSTR('000000000000000000000',1,20 - LENGHT(NEW.ITMREF_0)) || NEW.ITMREF_0 || SUBSTR('0000000000',1,10 - LENGHT(NEW.LOT)) || NEW.LOT || SUBSTR('0000',1,4 - LENGHT(ct)) || ct;
      INSERT INTO ZUART
        (ZUARTDM_0,ITMREF_0,CREDAT_0,STA_0,QTYSTU_0,LOT_0,STOFCY_0,VCRLIN_0,VCRNUM_0,VCRTYP_0)
      VALUES
        (codigo_dm,NEW.ITMREF_0,SYSDATE,0,NEW.QTYSTU_0,NEW.LOT_0,NEW.STOFCY_0,NEW.VCRLIN_0,NEW.VCRNUM_0,NEW.VCRTYP_0);
   END LOOP;
END CREA_REGISTROS_TRAZA;
/

{size: 12} And the error message I get States is just:
"The trigger was created with compilation errors."
Thanks for the help {size}

You must prefix your NEW "columns" with a colon, as in: NEW.

Update trigger that inserts the record in another table
I searched the forum and the web for an example like this and I can not find a:

A field is updated in the TABLE_A and it triggers a single record TABLE_B insert that has the old and the new value of the field.

I write a lot of complex data warehouse SQL-based reports, but very rarely do much PL/SQL, any help would be appreciated.
Thanks in advance.
Hello

You can specify that the trigger should fire only when certain columns are referenced, like this:
```
create or replace trigger test_fund_trig
before update OF FUNDING
on table_a
...
```
If you do this, the trigger will not draw on statements such as:
```
UPDATE  table_a
SET     mod_date = SYSDATE;
```
You should always use an IF statement, as I mentioned earlier, if you do not want to follow the updates where the value of this column has not really changed.

inserting multiple rows of another table with incremented recordid

Hi all

I HAVE TWO TABLES:

CREATE TABLE TEMP_TEST1)
NUMBER OF RECID,
TESTCHAR VARCHAR2 (500)
)

AND

CREATE TABLE TEMP_TEST2)
TESTCHAR VARCHAR2 (500)
)

Both the table contains data in it. I want to insert data from TEMP_TEST2 in TEMP_TEST1 with RECID incremented for each record, which must be greater than max (RECID) of TEMP_TEST1.
PS: I have to query insert only, I cannot make changes in the structure of table or RECID of TEMP_TEST1 is not automatically incremented.
Please suggest a query that selects the record of TEMP_TEST2 and TEMP_TEST1 insert with recid incremented for each record.

Thank you.

Trying to create a trigger that adds a value to a field based on another field

Hello
Im trying to set a trigger that will add a field to a table if another field = the same thing and one where the condition is met, but can't seem to get anything to do and can't find anything online suggesting the syntax.
the use of im tables are
Applications_History
Students
I need the trigger to identify if the 'status' field = applicant accepted when a new data column is added, if that is the case I need to identify the scope of student_number of applications_history and match it to the student_number on students field, I then need to add a 'Y' in the field 'put' corresponding to this student in the student table. I'm looking for without stopping for some type of syntax format online but could not find anything, is it still possible?
Thank you

Something like that?

create or replace trigger aiur_applications_history

after insert or update on applications_history

for each line

Start

If nvl (: old.application_status, 'x'). = 'candidate admitted '.

and: new.application_status = 'candidate admitted '.

then

students update

the value = 'y '.

where student_number =: new.student_number;

end if;

end;

Update multiple rows in a table at a time
Hi all

I write a stored procedure that fills all columns in a table, that table with a query with the exception of a single column, say 'ABC' column in this table. I have to load this left on column using a different query that refers to some other tables. How can I update this column 'ABC' with all its rows of data from a different query?

Thank you very much!!
If you post an update with a create table and insert statements, it would be useful... I think that you want to update a table with a select from another table using a join... is that correct?

c customer update
Set client_name =)
Select client_name
of another_customer_table one
where a.customer_id = c.customer_id_from_original_customer_table
)
where c.customer_id in (select customer_id from another_customer_table)

Where clause is required only if you don't want to update missing customer_ids to null.

How to insert multiple rows in a table by the user (pl/sql)
Hello
I was trying to insert several rows in a table by a user by some pl/sql, but not every time entry. :/
What is happening is that the program requires each time ask the user for the new value but the loop
1 values inserts actually four times (the loop is run four times). can any point on what I am
doing wrong or solutions will be fun ;)

what I wrote here

---------------------------------

Set serveroutput on
set verify off

declare

EmpNo number;
EmpName varchar2 (20);

Start

because loop me in 1.4
EmpNo: = & empno;
EmpName: = '& empname';

insert into values(empno,empname) of the employee;

end loop;

end;

-------------------------------

do not laugh at my code, I'm new to this oracle :D

Thank you, prospects for the future for a response

Thanks for the info, looks like a nice tool will ;) try
but I really want (my problem) in pl/sql

Take a quick re-read my post above.

PL/SQL is a process running on the database server. This process cannot interact with the client computer. He can't ask for user input, and it cannot display the output to the client. Client interface tools can only do. You are eager to get feedback from a user, if you need an interface tool to do. SQL * Plus can interface and application of entry, but only as variable substition, and it does not really provide a programming construct that allows you to run a program in a loop to do. Do this using SQL * Plus you must pair it with shell/dos scripting languages, but more ideally you should use an interface appropriate as Apex.

I was wondering if it all works in pl/sql to release cached data (as fflush (stdin) in c ++)

PL/SQL does not a customer entry, so there is no sense to have something to release the cached data. You pass the values of PL/SQL code using procedures or functions with parameters.

Delete multiple rows in the table.

How to remove several rows in the table at the same time?
I have a table with 10 rows.
I have a loop for delete lines 1, 3 and 6.
It deletes the row 1 and 3 of the Index out of Bounds exception.
I know why this is happening.
I'm looking for a function or something to delete several lines at once?
Thank you

It must be a logic error.

For each row, you delete, you should reduce the number of indexes.

For example

If you want to delete lines 1, 3 and 6 of a table that contains 6 rows

Remove row1 as Table.Row [0].instanceManager.removeInstance ();    [now how many lines will become 5]

Remove row3 as Table.Row [1].instanceManager.removeInstance ();     [Note that index is 1 because you have already deleted a record, and the index starts at 0.

Remove row6 as Table.Row [3].instanceManager.removeinstance ();      [already two deleted record, so 6-2-1 = 3 is your index to remove]

You understand the logic?

Find columns that exist in one, but that do not exist in another table?
I ' having a slight problem. I can't find an appropriate SQL query to return values for a column that exist in a table, but that do not exist in another (related).

TABLE CAR
(
PK CAR_ID,
CAR_TYPE
)

TABLE CAR_IN_REPAIR
(
PK ID,
FK CAR_ID,
FK REPAIR_SERVICE_ID
RETURN_DATE (NULL)
)

I want to show the records that appear in the table of the CAR, but who are not in the CAR_IN_REPAIR and that CAR_IN_REPAIR. RETURN_DATE is less than SYSDATE or zero (date of return unknown).

In short, I want the query to display the cars that are currenty in repair or does not know the date of return from the repair center (NULL)

I did a SQL query:

SELECT c.id
DRIVE c, CAR_IN_REPAIR r
WHERE c.id NOT IN r.car_id

the query returned no data but data is in the table of the CAR because he displayed when I SELECT * CAR?

Published by: OraNewbie on August 28, 2008 21:02
Try this-
```
strikeselect * from CARminusselect * from CAR_IN_REPAIR--strike--
```
```
select *
from CAR c
WHERE c.id NOT IN (
                     select r.car_id
                     from CAR_IN_REPAIR r
                  )
```
Hope this will help you.

Kind regards.

Create a trigger that send mail with attachment after insertion of a line in Oracle APEX

I want to create an insert after trigger on a table that is to send a mail with an attachment. Here is my code.
CREATE OR REPLACE TRIGGER tr_feedback
AFTER INSERT on REVIEWS
FOR EACH LINE
DECLARE
l_id NUMBER;
BEGIN
l_id: = APEX_MAIL. SEND)
p_to => ' [email protected] ',
P_FROM = >: NEW. E-mail
p_subj = >: NEW. Object
p_body = > "Please see the attachment."
p_body_html = > ' review of < b > please < /b > the attachment ")
APEX_MAIL. ADD_ATTACHMENT (p_mail_id = > l_id,)
p_attachment = >: NEW. FILE,
p_filename = >: NEW. FILE NAME,
p_mime_type = >: NEW. MIME);
END;
But when I insert data, I get the following error:
ORA-20022: Null value provided for the parameter p_filename.
ORA-06512: at "APEX_040200.WWV_FLOW_MAIL", line 1070
ORA-06512: at "APEX_040200.WWV_FLOW_MAIL_API", line 141
ORA-06512: at "TR_FEEDBACK", line 11
ORA-04088: error during execution of trigger 'TR_FEEDBACK '.
Now, how can I fix that? Thanks in advance.

Agree with the above. Triggers (ab) should not be used in this way. Nontransactional process should not be based on a transactional trigger. These processes are part of the business logic and should be at the level of the company of codification (Summit, you can add a process to be executed once the completed insertion)

Creating a trigger to run only when a new table is created
I know that I can use this to create the DDL create relaxation.
```
CREATE OR REPLACE TRIGGER 
  create_table_trigger
  AFTER CREATE ON SCHEMA
DECLARE
BEGIN
END;
```
Problem is that this trigger would run on CFDS as "Create sequence." How can I perform it only for 'Create Table' CFDS?

Check ora_sysevent coupled with ora_dict_obj_type in your trigger. This will help you capture the CREATE TABLE event.

In the map target TABLE2
SERVICE_ID = TABLE1. SERVICE_ID
PRODUCT_CODE = TABLE1. ATTR_VALUE

Use SQL IKM append control

Interface 2:

"Put a filter in your 1 on attr.name = array ' PROVIDER '.

In the map target TABLE2
SERVICE_ID = TABLE1. SERVICE_ID
PROVIDER = TABLE1. ATTR_VALUE

Do SERVICE_ID as KEY (when you click the column target in properties, you can see KEY under properties of the target column) and use the incremental update of the IKM Oracle.

PS: I assume that Oracle as the source and target.

And you can refer to the documentation,
