My trigger isnt working, i am getting the error
Missing IN OUT parameter at Index:: 1
could anyone help please

Hi,
the code works for me. The error message you posted here doesn't sound like an Oracle error -- what is the Oracle errorcode (ORA-xxxxx) that you are getting?
Best regards,

Help with mutating trigger

Hi all,
I have a trigger shown below is gives me the mutating error.
The error is to do with the select from the payments table (which it does not allow cos of the mutating effect).
Can anyone give me some ideas on how I can resolve this?
Thank you very much

Hi Anwar,
Thanks for this.
Can you please help me out here
I did the bit with creating a temporay table to hold the invoice_ids and then created a procedure that will be fired by the trigger, however because of the clause
IF :NEW.PAYMENT_STATUS='C' AND :NEW.PAYMENT_STATUS <> :OLD.PAYMENT_STATUS
I cant use a statement level trigger for this procedure and when i use the row level trigger i get the mutating error.
here is what i have got so far.
A temporary table which holds the invoice_ids (this is called payments_temp)
I then created a trigger as below which populates this temp table
TRIGGER insert_payments_temp BEFORE
UPDATE OF "PAYMENT_STATUS" ON "PAYMENTS" FOR EACH ROW
DECLARE
-- check if all the payments for that invoice have been received (completed)
-- if they are complete then sum all the payments for that invoice and compare to gross value on invoices
v_invoice_amount NUMBER;
v_gross_amount NUMBER;
thisproc CONSTANT VARCHAR2(80) := 'trap_errmesg for mco_transfer_status';
v_value VARCHAR2(150);
BEGIN
INSERT INTO payments_temp
VALUES (:NEW.invoice_id);
END insert_payments_temp;
Then I created a procedure below which will do the update
PROCEDURE "CHECK_INVOICE_PAID_IN_FULL_PRO" IS
-- check if all the payments for that invoice have been received (completed)
-- if they are complete then sum all the payments for that invoice and compare to gross value on invoices
v_invoice_amount NUMBER(20);
v_gross_amount NUMBER;
thisproc CONSTANT VARCHAR2(80) := 'trap_errmesg for mco_transfer_status';
v_value VARCHAR2(150);
BEGIN
-- We will sum all the payments for that invoice that have a value in payment_complete
--select sum(amount) into v_invoice_amount from payments where payment_complete is not null and invoice_id=:NEW.INVOICE_ID;
FOR x IN (SELECT invoice_id FROM payments_temp) LOOP
SELECT NVL(SUM(amount),0) INTO v_invoice_amount FROM payments
WHERE payment_complete IS NOT NULL AND invoice_id=X.INVOICE_ID;
SELECT NVL(gross,0) INTO v_gross_amount FROM INVOICES WHERE
invoice_id = X.INVOICE_ID ;
END LOOP;
-- We will also get the gross amount for the invoice to compare to the sum of the payments
IF v_invoice_amount = v_gross_amount
THEN
UPDATE INVOICES SET paid_date=SYSDATE;
COMMIT;
END IF;
END CHECK_INVOICE_PAID_IN_FULL_PRO;
Then finally the update trigger itself below
TRIGGER "NICKC"."CHECK_INVOICE_PAID_IN_FULL" AFTER
UPDATE OF "PAYMENT_STATUS" ON "NICKC"."PAYMENTS" FOR EACH ROW
DECLARE
-- check if all the payments for that invoice have been received (completed)
-- if they are complete then sum all the payments for that invoice and compare to gross value on invoices
v_invoice_amount NUMBER;
v_gross_amount NUMBER;
thisproc CONSTANT VARCHAR2(80) := 'trap_errmesg for mco_transfer_status';
v_value VARCHAR2(150);
BEGIN
-- Changed as requested by nicola on 12/09/05 IF :NEW.PAYMENT_COMPLETE is not null
IF :NEW.PAYMENT_STATUS='C' AND :NEW.PAYMENT_STATUS <> :OLD.PAYMENT_STATUS
THEN
CHECK_INVOICE_PAID_IN_FULL_PRO;
END IF;
END CHECK_INVOICE_PAID_IN_FULL;
However i still get the mutating error message and when i try to create a statemtnet level trigger i get the message say cannot use :NEW and :OLD values here.

I need help with a trigger mutating a table

I'll add the trigger I have written now at the bottom. Here is the problem that I have. We have employees and their families in an individual table.
A family is indicated by matching client, branch, and emp_id. An employee is indicated by individual_num = 1. All other numbers indicate family members. A person is determined to be terminated by having a date other than '2299/12/31' (It's a varchar(10) and very very wrong. Don't ask...) in the termination date column.
A family member can be terminated in the system independent of the rest of there family. However, if an employee is terminated then all active family members need the termination date set to the same date as the employee. If that termination date is then changed for the employee all family members with the same date need to have their dates updated.
I understand why this causes table mutation but I need a work around. Any ideas? Please...
CREATE OR REPLACE TRIGGER INDIV_EMP_TERM
after update on INDIVIDUAL
for each row
begin
if ( :new.INDIVIDUAL_NUM = 1 and :old.TERMINATION_DATE <> :new.TERMINATION_DATE ) then
if ( :old.TERMINATION_DATE = '2299/12/31' ) then
     update INDIVIDUAL
          set TERMINATION_DATE = :new.TERMINATION_DATE
          where CLIENT = :new.CLIENT
          and BRANCH = :new.BRANCH
          and EMP_ID = :new.EMP_ID
          and INDIVIDUAL_NUM <> 1
          and TERMINATION_DATE = '2299/12/31';
     else
     update INDIVIDUAL
          set TERMINATION_DATE = :new.TERMINATION_DATE
          where CLIENT = :new.CLIENT
          and BRANCH = :new.BRANCH
          and EMP_ID = :new.EMP_ID
          and INDIVIDUAL_NUM <> 1
          and TERMINATION_DATE = :old.TERMINATION_DATE;
     end if;
end if;
end;

Try your code like this below .It will help you to eliminate the mutating error

Help with AI Trigger!

Please help! I'm an experienced LabVIEW user, and this one is really
puzzling me. I have a (2) PXI-6070E MIO boards in a PXI chassis. What
I would like to do is have a data acquisition with an analog trigger.
When the analog trigger occurs, I would like to start a counter output.
Therefore, I'd really like to route the "AI start trigger" to the
counter gate. Here's what has happened:
1) I can set up the analog trigger, and the data acquires when the
signal goes above the trigger level, just like it's supposed to.
2) I can manually start the counter by toggling the gate by hand and
watching the output toggle.
3) I can't get the AI start trigger to be an output to anything--a PFI,
an RTSI line, nothing. How do I route this
signal to gate of the
counter? If I can get that, I know it will work.

I got it. Although I am not able to specifically route the AI trigger
to a PFI, I can route it to a RTSI line. (If I'm triggering a counter
from the same MIO board, I don't even need to do that--see below).
What I found is that buried deep in the Generate Delayed Pulse VI, there
is a VI called CTR Mode Config. There is a cluster input to this VI
which contains the parameter for the gate line. If you check the help
on this VI, it shows that you can select AI trigger or RTSI line as the
counter gate, but the cluster control they've put on the front panel
doesn't allow you to select this as an option.
Redoing the control (basically deleting it, putting the wiring tool on
the input, and then selecting create control) allowed me to select the
appropr
iate line, and thus my triggering worked correctly. I don't know
why they don't have all the selections available in the control they
made for this VI. *shrug*

Need help with creating trigger using instead of insert.

Hi all,
I am trying to create a trigger that can read the inserted Mail data from table1 and check if the Mail data matches the Mail data from table2. If the Mail data matches the Mail data from table2 it will get the EmpID from table2 and insert it into table1
column EmpID.
Here are table2 columns:
EmpID (int) Mail(varchar) Mail2(varchar)
101 [email protected] [email protected]
102 [email protected] [email protected]
table1 columns
EmpID (int)(primary key) Mail(varchar) Mail2(varchar)
If I insert [email protected] into table1 column Mail, I would like it to get the value for the EmpID from table2 before actually inserting the record into table1, by matching the Mail from table1 = Mail from table2.
I am using ASP.Net to insert the records into Mail and Mail2.
How can I achieve that?
I appreciate any help.

There should be two SQL statements in the stored procedure in order to accomplish the task?
Ideally you need to include logic as a part of your insert procedure itself. You should have a standard insert stored procedure which should include this logic and should be used for all inserts.
Also if EmpID field has to have a non NULL value always you may better off creating a foreign key constraint from Table1 to Table2 on EmpID column to enforce the Referential Integrity.

WOHOO! - You guys are stars! - Thanks everyone who helped with my trigger prob.....

I added the trigger logic to the before insert trigger created by designer and it works a treat.
Thankyou so much, I've learned bundles, hopefully I'll be abe to impart my knowledge to others in the future!

Like to know the final trigger.
Can you please post it.

Help with Oracle Table Audit Trigger

Hi Guys,
Need some help with the design of a trigger please. I have created one standard audit table where all sensitive data will be audited/inserted. The idea is to insert the column name and the old and new values here, dont want to maintain an audit table for each and every table there is, reporting would be a nightmare.
Trying to fetch all the column names from sys objects then looping through each and inserting the new and old values for them into the audit table. Everything else is fine apart from the actual :old and :new value inserts. The column name is coming from a variable in a cursor and this is where I seem to be failing.
Can anyone help please? What is the correct syntax to use?

What does auditing mean in the financial environment? "An audit is a professional, independent examination of a company's financial statements and accounting documents according to generally accepted accounting principles."
What does it mean in database terms? Surely, the basic definition would be the same, ito of a proper independent examination of changes in the database according to accepted principles?
And just how does a trigger live up to that? When it is fully dependent on being enabled for that transaction in order to examine it? It is trivial to disable a trigger, make changes, and re-enable it.
So what happens to your "auditing" then?
Do you really think that a trigger suffices as a means to audit changes in a table? And if so, what logic and reasoning do you use to discard Oracle's auditing features that are built into the core of the database?

Who can help me with a trigger?

Ok, the problem is: the table 'estadia' means 'stay' and 'quarto' means 'room'. I need to, before inserting on 'estadia', to check if that room is available or not.
I may do this:
insert into estadia values (4, 3, *3*, to_date('09.12.15', 'yy.mm.dd'), to_date('10.02.25', 'yy.mm.dd'));
but if, after this command, i do this:
insert into estadia values (5, 4, *3*, to_date('09.12.15', 'yy.mm.dd'), to_date('10.02.25', 'yy.mm.dd'));
it accepts and it shouldn't, because I'm putting users 3 and 4 in the same room at the same time.
the 3rd field is the room id and the next two fields are the entry date (data_entrada) and the exit date (data_saida). If a room is related to a specific stay in which the exit date hasn't gone by, that room shouldn't be available. Also, the exit date may be null, meaning that the exit date is unknown.
I hope to have been clear about my question.
Thanks, Chiapa

This is a fairly easy business rule which can be implemented using triggers. Here goes.
Tables (my version):
drop table stay;
drop table room;
create table room
(room_id     number not null primary key
,other_col     varchar2(10) not null)
create table stay
(stay_id     number not null primary key
,room_id     number not null references room(room_id)
,arrive          date not null check(trunc(arrive)=arrive)
,depart          date          check(trunc(depart)=depart)
,unique (room_id,arrive)
,check(arrive <= depart))
/The rule you are trying to implement is this one:
create or replace assertion no_overlap as
check(not exists
        (select 'two overlapping stays for a room'
         from stay s1
             ,stay s2
         where s1.room_id = s2.room_id
           and s1.stay_id != s2.stay_id
           and (s1.arrive between s2.arrive and nvl(s2.depart,s1.arrive) or
                s1.depart between s2.arrive and nvl(s2.depart,s1.depart))
/Sometime in a far far away future, we may be done now. That future has still to arrive though.
So here's the trigger-code and supporting objects:
create or replace procedure p_get_Lock(p_lockname    in varchar2) as
pl_id number(38);
pl_return number;

                                      ,hash_size => power(2,30));
-- Request the application lock in X-mode.
pl_return :=
dbms_lock.request(id                => pl_id
                   ,lockmode          => dbms_lock.ssx_mode

if pl_return not in (0,4)
then
    raise_application_error(-20000,'Could not serialize for business rule.');

Help with triggers

Hi All,
i have a few triggers that I need your help with.
The first trigger (below) is fired when an update is made to a column in an invoices table.
The question I have is to do with the exception section.
I want to change the status of the invoice if it fails to F.
This trigger has already complied fine but I have no test data yet to test against.
I was unsure of the mutating effect and was wondering if the exception section will cause it to mutate since it is trying to update the status of the current invoice being processed. Pls see below
create or replace
TRIGGER POP_STAGE AFTER
UPDATE OF "EXCHANGED_DATE" ON "INVOICES" FOR EACH ROW
declare
-- check if the invoice.mco_transfer_status has been updated to R
-- if it has then insert records into the relevant tables
-- Start the Insert based on the update of invoices.mco_transfer_status
ecode varchar2(100);
thisproc CONSTANT VARCHAR2(80) := 'trap_errmesg for transfer_status';
v_value varchar2(150);
BEGIN
-- do updates based on update of invoices.transfer_status column
IF :NEW.TRANSFER_STATUS='R'
THEN
-- Insert into E_TICKET_STAGE
INSERT INTO E_TICKET_STAGE (emco_document_number,exchanged_date,pax_seq,pax_forename,pax_surname,pax_type)
select :NEW.EMCO_DOCUMENT_NUMBER, :NEW.EXCHANGED_DATE,PX.PAX_SEQ,PX.FORENAME,PX.SURNAME,PX.PAX_TYPE
FROM PAX PX WHERE PX.BOOKING_ID=:NEW.BOOKING_ID;
-- Insert into SECTOR_STAGE table
INSERT INTO SECTOR_STAGE (emco_document_number,ps_id,sector_seq,pax_seq,fare_class,fare_basis,net_fare,tax,gross_fare,
flight_number,departure_date,dep_airport_code,dest_airport_code)
SELECT :NEW.EMCO_DOCUMENT_NUMBER, PS.PS_ID,PS.SECTOR_SEQ,PS.PAX_SEQ,PS.FARE_CLASS,PS.FARE_BASIS,PS.NET_FARE,PS.TAX,PS.GROSS_FARE,BS.FLIGHT_NUMBER,BS.DEPARTURE_DATE,
BS.DEP_AIRPORT_CODE,BS.DEST_AIRPORT_CODE
FROM PAX_SECTORS PS, BOOKING_SECTORS BS
WHERE PS.BOOKING_ID=:NEW.BOOKING_ID
AND BS.BOOKING_ID=PS.BOOKING_ID;
-- Insert into TAX_STAGE table
INSERT INTO TAX_STAGE (emco_docUment_number,PS_ID,TAX_SEQ,TAX_CODE,VALUE)
SELECT :NEW.EMCO_DOCUMENT_NUMBER, pt.PS_ID,TAX_SEQ,TAX_CODE,VALUE
FROM PAX_TAX pt,PAX_SECTORS ps
WHERE ps.BOOKING_ID=:OLD.booking_id and pt.PS_ID=ps.PS_ID;
-- Insert into CHARGES_STAGE table
insert into CHARGES_STAGE (emco_document_number,CHARGE_TYPE,CHARGE_AMOUNT)
select :NEW.EMCO_DOCUMENT_NUMBER, CHARGE_TYPE,VALUE FROM INVOICE_DETAILS IND
WHERE :NEW.INVOICE_ID=IND.INVOICE_ID;
END IF;
EXCEPTION
WHEN OTHERS THEN
ecode := SQLCODE|| ' '||sqlerrm ;
dbms_output.put_line(thisproc || ' - ' || ecode);
v_value := thisproc || ' - ' || ecode;
-- Insert into DOCUMENT_STATUS_STAGE ANY ERRORS DURING PROCESSING
insert into DOCUMENT_STATUS_STAGE (EMCO_DOCUMENT_NUMBER, STATUS,STATUS_DATE)
VALUES (:NEW.EMCO_DOCUMENT_NUMBER,v_value,sysdate);
update invoices set TRANSFER_STATUS='F' where invoice_id=:old.invoice_id;
END pop_stage;
The second trigger (also below) does a check on the payments table to see if the payment_complete date has been set.
If this has been set then we want to sum all the payments (based on invoice_id). once this sum has been made we want to compare this value to the value of the gross amount on the invoices table for that invoice. if they match (which shows the invoce has been fully paid) then we want to update the paid_date and set to sysdate.
create or replace
TRIGGER CHECK_INVOICE_STATUS AFTER
UPDATE OF "PAYMENT_COMPLETE" ON "PAYMENTS" FOR EACH ROW
declare
-- check if all the payments for that invoice have been received (completed)
-- if they are complete then sum all the payments for that invoice and compare to gross value on invoices
v_invoice_amount number;
v_gross_amount number;
thisproc CONSTANT VARCHAR2(80) := 'trap_errmesg for mco_transfer_status';
v_value varchar2(150);
BEGIN
IF :NEW.PAYMENT_COMPLETE is not null
THEN
-- We will sum all the payments for that invoice that have a value in payment_complete
select sum(amount) into v_invoice_amount from payments where payment_complete is not null
group by :OLD.INVOICE_ID;
-- We will also get the gross amount for the invoice to compare to the sum of the payments
select gross into v_gross_amount from invoices where
:OLD.INVOICE_ID = invoice_id;
END IF;
IF v_invoice_amount = v_gross_amount
then
update invoices set paid_date=sysdate;
end if;
end CHECK_INVOICE_STATUS;
Is this trigger sufficent?
Any tips will be appreciate.
Thanks

I didn't really look into your post (rather long) ... anyway, I have 2 words for you "stored procedures".

Mail.app - Applescript - Looking for help with my 1st Applescript

Okay… so I am taking the plunge. I've finally found something that is bugging me enough that I want to make a script to resolve it.
*Here's the situation:*
I use Smart Mailboxes a lot. It's my primary window into dealing with email.
I use MailTags (an addon for Mail) to apply keywords to messages, via Mail Act-On rules (an addon by the same company).
I use Smart Mailboxes to show me messages with various keywords etc.
What I have found is that Smart Mailboxes do NOT automatically update themselves. For instance, when a message in the Smart Mailbox is changed in such a way that the filter on that mailbox should not display it, the message will still sit there until I either leave the mailbox and return, or hit Rebuil in the Mailbox menu.
The same applies for when new mail comes into my Inbox. If there is new mail that qualifies for inclusion in the smart mailbox I am currently viewing, it will not appear until I do one of the above two things.
What I discovered was this script:
tell application "Mail" to activate
tell application "System Events"
click menu item "Rebuild" in menu ¬
"Mailbox" in menu bar 1 of process "Mail"
end tell
This is what got me thinking about scripting a solution.
The other option is to assign a keyboard shortcut to the Rebuild command. But I would like the Rebuild to take place automatically when I apply certain rules to messages. I want my Mail Act-on rule to trigger the a Rebuild. I figure I can do this by having it trigger the Rebuild script shown above.
*HERE IS MY QUESTION:*
Is there a way to have the script check what the currently active/selected Mailbox is? Or, put another way, can I get it to NOT run if certain mailboxes are selected?
Here's what I am thinking.
Under no circumstances do I want this script to be triggered if the current mailbox is NOT a smart mailbox, and IS any of my IMAP mailboxes… most especially the Inboxes. That would trigger a complete cleaning out and rebuilding of the entire IMAP inbox, which has many gigs of mail in it.
What I am trying to figure out, and would love some help with, is how I can make sure this script ONLY runs when the current mailbox is either ANY smart mailbox, or NOT an IMAP mailbox, or some other logic that keeps it from running in an IMAP mailbox.
Any tips are greatly appreciated.
With thanks,
Jonathan

Thanks Camalot,
I appreciate your help with this. I am also enjoying learning more about AppleScript. It seems much easier that other scripting languages, if for no other reason that it uses basic english logic and words.
When I run your script with an inbox selected, I get the following Result:
tell application "Mail"
get selected mailboxes of message viewer 1
--> {mailbox "INBOX" of account "JE Gmail"}
end tell
Result:
{mailbox "INBOX" of account "JE Gmail" of application "Mail"}
When I run it with a smart mailbox selected the following is produced:
tell application "Mail"
get selected mailboxes of message viewer 1
--> {current application}
end tell
Result:
{application "Mail"}
So get the impression it's not throwing up an error. Certainly, either way it does not run what I put into the On Error section, which was simply
display dialog "Success"
Is this useful? Can I test if the output contains the word "INBOX" ?
I notice that if I have, for instance, a SENT folder select, it gives the following result:
Result:
{mailbox "INBOX/Sent Messages" of account "[email protected]" of application "Mail"}
Which again has the word INBOX in there. Drafts comes up a little different.
Result:
{mailbox "Drafts ([email protected])" of application "Mail"}
So if there was a way to parse the result through a test against "INBOX" "DRAFT" etc then this might work. What do you think?
I have no idea how to go about that though, so your input would be very helpful.
Thanks,
Jonathan

Need Help with my Imessage

i need help with my imessage i am using a Iphone 4 ios 6.1.3 but when i go to settings>message>send and reecieve. i only get the options Apple ID: and You can be reached by iMessage at: my current email and add another email. my question is how do i get it to where imessage uses my cell phone number instead of my Email i have looked all over the web and no luck......

The hidden text should be sent for you automatically by the phone. From personal experience, this is automatic, but something has obviously tripped up somewhere on your phone.
It appears from reading the documentation, I would first try signing out of your Apple ID by going to Settings > Messages > Send and Receive then press your Apple ID, and press Sign Out. Then sign back in. This should hopefully trigger a re-activation of your mobile number. Your mobile number should be assigned to your Apple ID on first sign-in so hopefully this signing in and out should trigger an automatic re-activation.
Failing that, others have posted a reset of the phone, as does the support page I quoted. It appears this could be a last resort as a reset can be a bit of a pain (although if you Back your phone up via iTunes, you should be able to restore it to how it is currently). I would try the signing in and out method. Hopefully, fingers crossed, it should kick your phone back into action.

Need help with adjusting Javascript code to work in Adobe Edge (Countdown)

Hello
Im a newbie when it comes to working with Javascript and Adobe Edge and need a bit of help with adjusting some javascript code to work with Adobe Edge. A friend of mine helped me with making this javascript code: Edit fiddle - JSFiddle
Its a simple countdown which counts down to a certain time at a certain date. What I aim to do is to add this code as a trigger on a text-element called "countdown" (within a symbol called "count").
I have tried to do this as the code is, but it does not work. Anyone have any suggestions?
Thanks!
Mvh,

Hello again
I have stumbled upon a problem with these animations; They crash the browser after viewing them a little while, usually less than 30 seconds in.
Is this problem also occuring when you watch the animations?
Is the countdown-code to much for the browsers to handle?
Thanks in advance for your answers.
Sincerely,
Øyvind Hermans

Need Help with a Flash Web Project

Hello, everyone. I am trying to use Flash to make a two-step
system. I want the flash document to, first, allow a person to
upload multiple image files and then, second, for the flash
document be able to create a slideshow with the uploaded images and
fade in and out from each image until the slideshow is over. I want
it to be where the flash document creates its own slideshow with
the images that are uploaded in the first step that I mentioned. I
want it to do it completely on its own so I need to know how to
give it the proper AI so that it can do this task.
So, are there any tips that anyone has on how to do this? Can
anyone tell me exactly how to do this? I really need help with this
for my new website project. Thanks in advance, everyone!

The problem with the text not appearing at all has to do with you setting the alpha of the movieclip to 0%. Not within the movieclip, but the movieclip itself. The same for the xray graphic, except you have that as a graphic symbol rather than a movieclip. To have that play while inhabiting one frame you'll need to change it to a movieclip symbol.
To get the text to play after the blinds (just a minor critique, I'd speed up the blinds), you will want to add some code in the frame where you added the stop in the blinds animation. You will also need to assign instance names for the text movieclips in the properties panel, as well as place a stop(); in their first frames (inside).
Let's say you name them upperText and lowerText. Then the code you'd add at the end of the blinds animation (in the stop frame) would be...
_parent.upperText.play();
_parent.lowerText.play();
The "_parent" portion of that is used to target the timeline that is containing the item making the command, basically meaning it's the guy inside the blinds telling the guy outside the blinds to do something.
You'll probably want to add stops to the ends of the text animations as well.
If you want to have the first text trigger the second text, then you'd take that second line above and place it in the last frame of the first text animation instead of the blinds animation.
Note, on occasion, undeterminably, that code above doesn't work for some odd reason... the animation plays to the next frame and stops... so if you run into that, just put a play(); in the second frame to help push it along.
PS GotoandPlay would actually be gotoAndPlay, and for the code above you could substitute play(); with gotoAndPlay(2);

Help with creating a sql file that will capture any database table changes.

We are in the process of creating DROP/Create tables, and using exp/imp data into the tables (the data is in flat files).
Our client is bit curious to work with. They do the alterations to their database (change the layout, change the datatype, drops tables) without our knowing. This has created a hell lot of issues with us.
Is there a way that we can create a sql script which can capture any table changes on the database, so that when the client trys to execute imp batch file, the sql file should first check to see if any changes are made. If made, then it should stop execution and give an error message.
Any help/suggestions would be highly appreciable.
Thanks,

Just to clarify...
1. DDL commands are like CREATE, DROP, ALTER. (These are different than DML commands - INSERT, UPDATE, DELETE).
2. The DDL trigger is created at the database level, not on each table. You only need one DDL trigger.
3. You can choose the DDL commands for which you want the trigger to fire (probably, you'll want CREATE, DROP, ALTER, at a minimum).
4. The DDL trigger only fires when one of these DDL commands is run.
Whether you have 50 tables or 50,000 tables is not significant to performance in this context.
What's signficant is how often you'll be executing the DDL commands on which the trigger is set to fire and whether the DDL commands execute in acceptable time with the trigger in place.
