Insert into a table using DB trigger

Hi,
I want to create a trigger on mytableA during INSERT or UPDATE:
When a record is created or updated in mytableA, I would like to insert a record into mytableB.
Before inserting, I would like to check if the corresponding mytable data already exists in the mytableB.
I was wondering if there's any better PLSQL code rather than using something like this.
select count(1) from mytableB where...
if count(1) <0 then
insert into mytableB
end if;
OR
use a no data found logic
Note: I will not be doing an UPDATE to mytableB if the record already exists.
Thanks in Advance.

Hi,
I am using 10g.
Could you give me an example on how to form a MERGE for DB trigger.
I tried something like this:
MERGE INTO mytableB
USING (SELECT col1,col2,col3 FROM mytableA) A
ON (A.col1=:new.col1)
WHEN NOT MATCHED THEN INSERT (col1,col2,col3e)
VALUES (:NEW.col1,:NEW.col2,:NEW.col3);
But since I am write a trigger on mytableA , SELECT might cause trigger mutating.
Please suggest.
Thanks.

Can select, but cannot insert into oracle tables using php.

I am having trouble inserting data into a tables in oracle using PHP. I can insert into the tables using baninst1, but nothing else. I can't even insert using the tables' owner. Every time I try I get the ORA-00492 error of table or view does not exist. However, I can run a select statement just fine. So far, baninst1 is the only user that can actually do inserts. I've triple checked all the table grants and everything is fine. Also, I can copy/paste the exact insert statement into SQL*Plus and it works with the correct user. It doesn't have to be baninst1. I've tried everything I can think of. I've tried putting the table name in quotes, adding the schema name to the table, checking public synonyms, but everything appears to be ok. I would greatly appreciate any suggestions others may have.
I'm using PHP 5.2.3 with an oracle 9i DB.

Here is the code that doesn't work. It works only with baninst1, no other username will work and all I do is change the my_username/my_password to something different. This is one example function where I try to do an insert, but it doesn't work on any of the tables I try.
Thanks for looking.

How to insert into two tables using a Single ADF creation form?

Hi,
I need to make a ADF Creation Form that will insert the data at same time in two tables... Like i have two tables Track (Track_id,Track_Name)
and Module ( Module_id, Track_id, Module_name, Module_Short_name) and i have to insert the data in both the tables using Same Creation Form.
can anybody help me out and gave me the solution,how to do that?
Thanks

if you want to insert different data into two different tables then you can drag the two data objects into creation form..
If you want to duplicate the data inserted in the one table to another then you can follow two approach
1. Drag and drop one table, When Save button is invoked then insert data into another table using callable statement.
or
2. Create on-insert trigger in Table1 where you can insert data into table2.

It appears you're missing the format mask in the TO_CHAR, ...
TO_CHAR(:new.apth,'YYYYMMHR24MISS')
The full code would help a bit more.

From Oracle 9.2 onwards we can do clever things with records:
SQL> select * from tab1
2 /
K F
Z X
A X
SQL> declare
2     r tab1%ROWTYPE;
3 begin
4     for r in ( select * from tab1 order by key ) loop
5       insert into tab12 values r;
6     end loop;
7 end;
8 /
PL/SQL procedure successfully completed.
SQL> select * from tab12
2 /
K F
A X
Z X
SQL> But as K Richards has pointed out you can do this with a straight INSERT ... SELECT statement...
SQL> roll
Rollback complete.
SQL> insert into tab12
2 select * from tab1 order by key
3 /
2 rows created.
SQL> select * from tab12

Insert into a table using select statement

I have a table aa_table which alread has data for 3 columns now i need to insert
the date for the 4th column C_id as shown below
INSERT INTO aa_table s(s.c_id) values (select id from C_table c ,aa_table s
where c.cin in( select s.cin from aa_table))
Its says missing expression?
Any one know what is wrong with this.
Thanks

yes this will update all the rows in the table
UPDATE aa_table a
   SET c_id = (SELECT ID
                 FROM C_table c
                WHERE c.cin = s.cin)this will update selected rows only
UPDATE aa_table a
   SET c_id = (SELECT ID
                 FROM C_table c
                WHERE c.cin = s.cin)
WHERE EXISTS (SELECT 'c'

Insert into multiple tables using a page variable

Hi Guys,
I was going to trawl the PL/SQL forum for this but as I need to use a page variable I thought I would try here first.
I have 4 tables 2 live and 2 archive, company_table, company_table_arch, product, product_arch the tables are set up with a company Id as the join.
you can have multiple products to a company.
what I want to do is have an archive button on a form that will select the current record on the company table, and insert it into archive then select all records with that id in the product table and insert them into the product_arch table.
I was thinking about doing this as a couple of page proccess, sound about right?
the other option was using a package,
is it possible to use page variables in a package? If so what is the sintax
cheers
Bjorn

OK, I have got the basis of this working I press the archive button and the records update as per the code.
I have one problem however.
The button is on a form. and if the user updates the form then presses the archive button it copies the data before the table is updated (the table is updated using a save button).
One way round this would be to jump to an "are you sure?" page
Does anyone know a better way of doing this?
cheers

Inserting into a table which is created "on the fly" from a trigger

Hello all,
I am trying to insert into a table from a trigger in Oracle form. The table name however, is inputted by the user in am item form.
here is what the insert looks like:
insert into :table_name
values (:value1, :value2);
the problem is that forms does not recognize ::table_name. If I replace :table_name with an actual database table, it works fine. However, I need to insert to a table_name based from oracle form item.
By the way, the table|_name is built on the fly using a procedure before I try to insert into it.
Any suggestion on how can I do that? My code in the trigger is:
declare
dm_drop_tbl(:table_name,'table) // a call to an external procedure to drop the table
dm_create_tbl(:table_name,'att1','att2');
insert into :table_name
values (:value1, :value2);
this give me an error:
encounter "" when the symbol expecting one.....

Hi ,
You should use the FORMS_DDL built_in procedure. Read the on-line documentation of forms ...

Creating a button for inserting into a table

What I can't do, because I've never needed to, is to create in a page (where I have a Interactive report) a button that when is clicked performs a simple sql (for example an insert into a table using some page item values).
How can I do it?
Thanks

Here are some of the steps:
1) Create the button.
2) Then right click on the button name and select Create Dynamic Action
3) Give the DA a name, click next
4) On the "When" Step, Event should already be "Click" and the button name should be filled in
5) For Condition, you would have a condition for when you want the button display. Say, if your page items have a certain range of values then display this button. No condition means the button is always displayed.
6) For the "True Action" Step, for Action select "Execute PL/SQL Code"
    [There are other ways to do this, but this is straight-forward for me.]
7) The in the PL/SQL Code block enter say:
Begin
INSERT INTO EMP (EMPNO, ENAME, HIREDATE)
          VALUES (:P6_EMPNO, 'MARK1970', :P6_HIREDATE);
COMMIT;
END;   --- You would likely make them all page item variables
8) Here the part I'm not 100% sure of.
    For "Page Items to Submit", name the page items used in YOUR QUERY -- in my example these are P6_EMPNO,P6_HIREDATE   (Note no use of & or : or . here)
    Hmm. Start by putting nothing in the "Page Items to Return".   If that fails, then try the same page items P6_EMPNO,P6_HIREDATE there as well.
[ I'm too lazy to go run this down at the moment.]
9) I think that's it.

Abort inserting a record in a table using a trigger

Hi there,
Is there any way to abort inserting a record in a table using a trigger?
For full details, I have the following table ("myTable"):
BSC INTEGER NOT NULL,
BTS VARCHAR2(20) NOT NULL,
INFO1 INTEGER,
INFO2 INTEGER
myTable_PK = PRIMARY KEY (BSC,BTS)
I have also a stored procedure that imports a data from text file and inserts them to the specified table (using UTL_FILE package). The stored procedure works great.
But the thing that in the text file itselft it might be (due to third-parity report generation bug) that the primary key will be violated or the BSC/BTS field has null value. In such case I just want to ignore the insertion statement using a trigger.
Thanks

Ok Jens, could you tell me what exception could I use?
Below a protion of my StoredProcedure.
CREATE OR REPLACE PROCEDURE update_myTable() IS
FHANDLE UTL_FILE.FILE_TYPE;
BSC INTEGER;
BTS VARCHAR2(20);
INFO1 INTEGER;
INFO2 INTEGER;
BEGIN
FHANDLE := UTL_FILE.FOPEN('LOG_FILE_DIR',FILENAME,'R',4000);
LOOP
UTL_FILE.GET_LINE(FHANDLE,STR);
-- Process the line STR and generates BSC, BTS, INFO1, and INFO2 values
EXECUTE IMMEDIATE 'INSERT INTO myTable VALUES(:1,:2,:3,:4)' USING BSC,BTS,INFO1,INFO2;
END LOOP;
EXCEPTION WHEN NO_DATA_FOUND THEN UTL_FILE.FCLOSE(FHANDLE);
END UPDATE_R205BTS;
Remember that I am already using an exception with NO_DATA_FOUND to indicate the end of file then closing it.
Thanks for your reply

Inserting Multiple Rows into Database Table using JDBC Adapter - Efficiency

I need to insert multiple rows into a database table using the JDBC adapter (receiver).
I understand the traditional way of repeating the statement multiple times, each having its <access> element. However, I am just wondering whether this might be performance-inefficient, as it might insert records one by one.
Is there a way to ensure that the records are inserted into the table as a block, rather than record-by-record?

Hi Bhavesh/Kanwaljit,
If we have multiple ACCESS tags then what happens is that the connection to the database is made only once. But the data is inserted row by row.
Why i am saying this?
If we add the following in JDBC Adapter..logSQLStatement = true. Then incase of multiple inserts we can see that there are multiple
<i>Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','1000')
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','2000')</i>
Doesnt this mean that rows are inserted one by one?
Correct me if i am wrong.
This does not mean that the transaction is not guaranted. Either all the rows will be inserted or rolled back.
Regards,
Sumit
