Using user_tab_columns on the trigger

dear all
i need to use user_tab_columns on the trigger before delete
like ex
SELECT a.column_name
INTO l_col_name
FROM user_tab_columns a
WHERE a.table_name = 'EMPLOYEE' AND a.nullable = 'N';
this is not work because the query not retrieve column name but emp_no is not null , if any suggestion to solve this issue?

i need to use user_tab_columns on the trigger before
delete And what business case you are trying to solve?

Error in Forms while creating the trigger- WHEN-CREATE-RECORD

Hello,
Right now I am using 11g client side and 10g database.
I am constantly getting an error while creating triggers in 11g.
I have created a sequence in SQL developer using the following code:
create sequence loc_id_sequence
start with 14;
After creating the sequence. I am trying to write the PL/SQL code in forms builder for the trigger WHEN-CREATE-RECORD
declare
loc_id number;
begin
loc_id := loc_id_sequence.nextval;
end;
But I have been getting the following error constantly. Can anyone please help me?
"Error 0 at line 5, column 4
SQL statement ignored".
Can anyone please tell me why I am getting that error

In fact, even I thought there might be some problem with the connectivity with the 10g database and 11g client but the other DB related code works.
I just have the problem with using sequence for the trigger WHEN-CREATE-RECORD.
In fact I also tried using WHEN-NEW-RECORD-INSTANCE smart trigger instead of WHEN-CREATE-RECORD for the same sequence. But even that doesn't work.
Do u have any idea of what that error means?

Using PFI0 as a trigger and PFI1 as an input on PCI-5114

Hi,
I have a NI-5114, and I'm currently using PFI0 as the trigger, and reading out the two analog channels. I'd like to add a second digital input through the other PFI so I can simply test if something is on or off (already a digital signal). So, when PFI0 triggers, it digitizes the two inputs and reads whether or not PFI1 is on or off (no timing necessary). Is there a trick to get this done?
Thanks,
Karl

Hello Karl,
Since the PFI lines are generally used as triggers, we cannot read a PFI line unless you are specifically triggering off it. What you could do is as soon as you receive a trigger you can export a trigger of PFI1 which you could connect to one input of an external AND gate and second one is the signal you want to monitor. or can use another DIO DAQ device like USB-6501 to monitor the status of external digital signal.
Good Luck

How to use ABAP Webservice to Trigger the start of BPMN

Hello,
My scenario is that i define a webservice in the SAP ECC system and import it in the process composer as the service interface. As to the start event, i set the above service interface and operation as the trigger service.
After then, i call this webservice in the user exit of a T-Code. However, the BPMN is not started by this webservice call.
Anyone can explain on this and tell me how to use the ABAP webservice as the starting event service interface?
Thanks in advance
Erick

Hi Erick,
When you develop a process model and use some arbitrary service interface in the message start event then this will be exposed on the Java / BPM system you deploed the process definition on.
That allows you to start the process via this web service once you know its endpoint.
So in case you want to start your process from the ABAP side you would need to call this endpoint on the Java side out of your ABAP system.
Simply calling the web service / code on your ABAP system and hoping that this will also invoke the Java stack won't work I AFAIK.

I am using PCI-6033E IO card and i would like to send 5 volts (high logic ) to the trigger box. the trigger box will trigger the frame grabber card, that i am using for image acquisition.

Hello;
The first thing you need to figure out is the shape of the trigger pulse needed.
In case you just need a logic high TTL pulse, you can use one of the digital lines of your DAQ device.
In case you need a pulse train (multiple trigger pulses), you will need to configure one of the general purpose counters to accomplish that task.
You can find examples in both Labview and NI-DAQ showing how to program your DAQ board to accomplish both approaches.
Hope this helps.

Stop one Daq but without use the trigger

Hello everybody,
I have one while loop and in it I have my DAQ, one time I have start with the Data Aquisition I need stop it and re-configure it again, but it is indepently of the trigger and I can't stop the while loop either.
Is there some path to do it??
Thanks
Gonzalo De Francisco

Dear Gonzalo
You are talking about pausing a while loop, right? If so, this post http://forums.ni.com/ni/board/message?board.id=170&message.id=10689&requireLogin=False could be helpful.

How to get the table name in the trigger definition without hard coding.

CREATE TRIGGER db.mytablename
AFTER UPDATE,INSERT
AS
    INSERT INTO table1(col1)
    SELECT InsRec.col1
    FROM
    INSERTED Ins
   --Below i am calling one sp for which i have to pass the table name
   EXEC myspname 'tablename'
In the above trigger,presently i am hard coding the tablename
but is it possible to get the table name dynamically on which the trigger is defined in order to avoid hard coding the table name

I really liked your audit table concept. You inspired me to modify it so that, the entire recordset gets captured and added a couple of other fields. Wanted to share my end result.

Its bit urgent
NO - it is NOT urgent. Not to us.
If you have an urgent problem you need to hire a consultant.
I have a performance issue in the below code,
Maybe you do and maybe you don't. How are we to really know? You haven't posted ANYTHING indicating that a performance issue exists. Please read the FAQ for how to post a tuning request and the info you need to provide. First and foremost you have to post SOMETHING that actually shows that a performance issue exists. Troubleshooting requires FACTS not just a subjective opinion.
where i am trying to insert the data from table_stg into target_tab and in parent_tab tables and then to child tables via cursor with bulk collect .the target_tab and parent_tab are huge tables and have a row wise trigger enabled on it .the trigger is mandatory . This timetaken for this block to execute is 5000 seconds.Now my requirement is to reduce it to 5 to 10 mins.
Personally I think 5000 seconds (about 1 hr 20 minutes) is very fast for processing 800 trillion rows of data into parent and child tables. Why do you think that is slow?
Your code has several major flaws that need to be corrected before you can even determine what, if anything, needs to be tuned.
This code has the EXIT statement at the beginning of the loop instead of at the end
    FETCH stg_cursor BULK COLLECT INTO v_rt_all_cols LIMIT limit_in;
              vstep_no := '4';
              vtable_nm := 'after fetch';
--EXIT WHEN v_rt_all_cols.COUNT = 0;
    EXIT WHEN stg_cursor%NOTFOUND;
The correct place for the %NOTFOUND test when using BULK COLLECT is at the END of the loop; that is, the last statement in the loop.
You can use a COUNT test at the start of the loop but ironically you have commented it out and have now done it wrong. Either move the NOTFOUND test to the end of the loop or remove it and uncomment the COUNT test.
WHEN OTHERS THEN
ROLLBACK;
That basically says you don't even care what problem occurs or whether the problem is for a single record of your 10,000 in the collection. You pretty much just throw away any stack trace and substitute your own message.
Your code also has NO exception handling for any of the individual steps or blocks of code.
The code you posted also begs the question of why you are using NAME=VALUE pairs for child data rows? Why aren't you using a standard relational table for this data?
As others have noted you are using slow-by-slow (row by row processing). Let's assume that PL/SQL, the bulk collect and row-by-row is actually necessary.
Then you should be constructing the parent and child records into collections and then inserting them in BULK using FORALL.
1. Create a collection for the new parent rows
2. Create a collection for the new child rows
3. For each set of LIMIT source row data
a. empty the parent and child collections
b. populate those collections with new parent/child data
c. bulk insert the parent collection into the parent table
d. bulk insert the child collection into the child table
And unless you really want to either load EVERYTHING or abandon everything you should use bulk exception handling so that the clean data gets processed and only the dirty data gets rejected.

Using a link to trigger a delete action on form page?

Hello,
I have been unable to find an explanation about how to do this in the documentation, these forums or the old interakt forums.
Is it possible to use a link to trigger the delete action on a form page?
If so how is it done?
Thanks in advance!

Sorry Purple.. I know that there is a delete link that triggers the delete transaction on the form page..
The question was if anybody knew if I am able to use a link to trigger that delete transaction (on the form page), much like a dynamic list has a link that will trigger the delete transaction on the form page.
I don't want to use a dynamic list in this case though. :)
Thanks anyways,
Drew

Error while deploying the trigger

Hi All,
In the trigger given below I want to append the data from all the table columns , to convert the numeric data to string i am using to_char function , but when i try to deploy the trigger i am getting the error.
What could be the problem here?
Is there any alternate way to achieve the same??

:NEW cannot be used in After Delete Trigger ?

Hi,
Is there any way to get the :NW.value in the After delete trigger for each row. My requirement is audit log of the end user DML operations along with user Name (HERE THE USER IS NOT THE ORACLE USER, BECAUSE OF THE LARGE NUMBER OF END USERS WE ARE MAINTAINING ONE TABLE TO CREATE USER NAME & PASSWORD, WHEN THE USER LOGIN TO ORACLE FORM SCREEN, ASSIGN THE USER NAME TO GLOBAL VARIABLE) & Action Date.
Here is my code for trigger - It is working fine with INSER & UPDATE but for DELETE User is NULL

Thanks in advance.

Rizly,
As i mentioned in the above post, you should remove the references of :old and :new when you are trying to use the global variables. These values are only significant when you the talk about the record in the table.
For the scenario, you explained, your trigger would insert two records....The trigger would be fired twice.. once during the insert and once during the delete. The audit table will have two records indicating both the actions..
Take a look at this example below...I am artificially manufacturing a user id in the package test_pkg and using that in the insert trigger. As i explained above, you dont need the :old and :new references because the user id is not a column in the table . hence the :old and :new references have no relevance.
Also note that, for the delete, I use the :old value and for the insert, I use the :new value.
for update, I assume you want to store the old record and hence used :old (you can of course use :new too..technically.).
I don't have access to a forms environement, but the user id logic should be similar to what I described below.

2     id number,

Processing LONG RAW in the trigger

I'm currently using Oracle 7.3.4.x. I'd like to perform in the
update trigger of LONG RAW column the copy of that value to
another table. Since the :new and :old is prohibited in triggers
and you cannot defined variables as LONG RAW data type in the
trigger I couldn't work out any solution to this problem.
Any one get any idea how to do that?
Thanks,
Mariusz.

Hi!
You will not be able to do "select * from ..." from a table with a LONG column. However you will be able to do a select successfully by using the individual column name(s). The other thing is, in order to see the full content of the LONG column you will have to do do "set long nnnnn" where nnnnn represents the maxumum length of the values in the LONG column.
Hope that helps.

I am trying to get my vi to trigger, not sure where to add the trigger

I need a vi that can trigger using an analog rising edge (1V), then produces a square wave (any square wave will do for now), and then show the measurement of the waveform. Attached is the code that I have made so far. Not sure how to get a trigger attached, or where to place the trigger, onto what I have done so far. Another question is where to have it triggered from, do I need to add another generate waveform to produce the trigger signal?
Any help is appreciated!!

Hi,
You can place a DAQmx start trigger VI in the code at the top, between the DAQmx Timing and DAQmx write VIs, and then set the trigger type to "Analog Edge" and specify the channel to trigger from (in this case I think you would use the APFI line on your card). Check out the 'Voltage - Continuous Output' Example' if you need help implementing this in code, that example covers analog output with different types of triggering in a setup similar to yours.

Using to pass the current user while creating a procedure

I have a .sql script that several people use to help set-up test beds but some users call the test procedures from a separate schema. The .sql creates a table (TABLE_A) and then a procedure that when run will create a trigger on a separate table (TABLE_B) that basically writes all info to TABLE_A. The problem is that if the .sql is run under schema SCOTT and then the procedure is run from schema JOE to create a trigger on JOE.TABLE_B, the trigger will try to write copy info to just TABLE_A instead of SCOTT.TABLE_A. My plan is to add a new input variable to the procedure for the schema where the procedure is located and set the default to the schema of the user running the .sql.
I can't seem to figure out how to call the current user and then pass it to a procedure as a DEFAULT input variable. Any help would be greatly appreciated.

OK, sadly, that did not work. What that provided to me was user that runs the procedure. If I run it as SCOTT it gives me SCOTT, but if I run as JOE, it gives me JOE.
I created an example of what I am trying to do (it is all run in a .sql file). Let me know if this is a bad example....

Call a Form using Webutil from the Menu loose focus on the applet

Hello,
I have the following problem:
When calling a form using webutil from the menu the focus on the applet (I mean the Forms Application window) is lost and I have to click on the window to get back the focus on the application.
Any advice ?

Try to use the NO_HIDE parameter in the CALL_FORM() built-in.
