Isn't this Trigger code error prone?

Version: 10g Release 2
I have come across a Trigger code where the :NEW pseudo variable is being assigned value like
SELECT emp_oid into :new.emp_oid FROM emp_dtls WHERE EMP_NO =:NEW.EMP_OID;Apparently, the code is working fine. But isn't this error prone?

It is not very useful to post this single line. One doesn't even know on which table this trigger fires, nor the relationship with the affected table and the emp_dtls table, nor whether an exception handler was programmed.
(Probably not).
If my assumption is correct no exception handler was programmed, this would have resulted in kick-ass time, as the code may result in either the NO_DATA_FOUND exception or the TOO_MANY_ROWS exception.
Anyone writing that kind of code needs to be escorted to the door of unemployment immediately.
BTW will anything bad happen if you post a question consisting of more than 1 line. Salary substracted? Fingers chopped off by your boss?

How can i minimize this trigger code

Hi,
I've written the following trigger ,based on the requirement...
Requirement is following:
After updating the src table(EMPS) corresponding data need to be replicated to dest (REP_EMPS)
While UPDATING ('STATUS') the following conditions to be matched
*(1) updating from any char to 'V then modtp= 'I' AND 'D'*
*(2) updating from 'V r to any char then modtp= 'I' AND 'D'*
*(3) ANY TO ANY THEN modtp='U'*
*(4) while deleting modtp='D'*
So the following trigger is working fine ..
But my doubt is can i even be minimize the code so as to achieve the requirement
CREATE TABLE TEST.EMPS
EMPNO   NUMBER,
ENAME   VARCHAR2(11 BYTE),
STATUS CHAR(1 BYTE)
CREATE TABLE TEST.REP_EMPS

What is wrong with this trigger code?

Hi folks,
Just wondering whether I might be missing something here about Oracle 9i, that one of you might notice, either from the syntax perspective, or regarding a bug? The code below compiles in the database I have, but the trigger does not fire, and no data is being inserted into the tables. The trigger is owned by sys, and the insert statements are in dynamic sql because I don't want the trigger not to compile if ever the tables are deleted from the b1dev schema.
Incidentally, this same trigger works well on Oracle 10.2.1.0 and Oracle 11.1.0. Any feedback would be much appreciated.

I have taken out the 'commit' and have added the 'when others then null' exception clause, but I would imagine there is a better way to do it than this? I don't want to do an insert into another table either. With Oracle 11g, this gives me the compile time warning....

Isn't this a typo error?

http://java.sun.com/docs/books/tutorial/java/IandI/override.html
Here's some code that's been posted on here before:
public class Animal {
    public static void testClassMethod() {
        System.out.println("The class method in Animal.");
    public void testInstanceMethod() {
        System.out.println("The instance method in Animal.");
public class Cat extends Animal {
    public static void testClassMethod() {
        System.out.println("The class method in Cat.");
    public void testInstanceMethod() {
        System.out.println("The instance method in Cat.");
    public static void main(String[] args) {
        Cat myCat = new Cat();
        Animal myAnimal = myCat;
        Animal.testClassMethod();
        myAnimal.testInstanceMethod();
}Based on what that lesson was trying to teach shouldn't the line
Animal.testClassMethod();be written as
myAnimal.testClassMethod();???

I didn't ignore this thread, just took a rest as it was late for me, sorry. Thx for the replies. However, what you've replied I've no problem in understanding. I get the point that instances of a class belong to an object whereas members of a class belong to the class. It's just that I thought the author of that lesson meant the line
Animal.testClassMethod();to be
myAnimal.testClassMethod();My reasoning was the topic of the lesson itself, "Overriding and Hiding Methods". An important point of that lesson is the following:
The distinction between hiding and overriding has important implications. The version of the overridden method that gets invoked is the one in the subclass. The version of the hidden method that gets invoked depends on whether it is invoked from the superclass or the subclass. Let's look at an example that contains two classes.As a reader at this point I'm thinking the author is going to demonstrate the above quote with the following two classes
public class Animal {
    public static void testClassMethod() {
        System.out.println("The class method in Animal.");
    public void testInstanceMethod() {
        System.out.println("The instance method in Animal.");
public class Cat extends Animal {
    public static void testClassMethod() {
        System.out.println("The class method in Cat.");
    public void testInstanceMethod() {
        System.out.println("The instance method in Cat.");
    public static void main(String[] args) {
        Cat myCat = new Cat();
        Animal myAnimal = myCat;
        Animal.testClassMethod();
        myAnimal.testInstanceMethod();
}Well, how does the line "Animal.testClassMethod();" demonstrate the above quote? It doesn't. It simply makes a direct call to a static method using its full name. It has nothing at all to do with objects, so yes, if you remove the other three lines in main() this one still works. Now if you change that line to "myAnimal.testClassMethod();" it still calls the static method from the superclass! But why? Afterall "myAnimal" holds a reference to a Cat! And so the line from the above quote,
The version of the hidden method that gets invoked depends on whether it is invoked from the superclass or the subclass.rings in my mind. So, overall I'm thinking there's a typo here and that the author meant "myAnimal.testClassMethod();". Well? I'm just being curious.

Code Error 5 message in Indesign CS4

Sorry second part, I brought a new internal hard drive for my desktop computer had Tekserve here in New York City install the hard drive in my Intel Mac IMac computer. Reloaded all of my Premium CS4 creative suite software into this new hard drive all with all of my other software fresh from the cd rons.

Part of Photoshop isn't functioning. Under adjustments, when HDR toning is clicked on I get a code: Error 48: File or folder does not exist. Line:11 - $.evalFile(g_StackScriptFolderPath "StackSupport.jsx"); How can it be fixed?

The phone company was here working on something while I was gone. They sat down at my computer (iMac) and since then HDR toning doesn't work. Get the code: Error 48: File or folder does not exist. Line: 11 -> $.evalFile(g_StacScriptFolderPatch + "StackSupport.jsx"); How can this be fixed?

Go to //Applications/Adobe Photoshop [Version]/Presets/ Scripts/Stack Scripts Only/ and see if StackSupport.jsx is there. If it is not, uninstall and reinstall Photoshop to have it added back in. If it is there, first try recreating the Photoshop Preferences (hold down Command+Option+Shift while launching Photoshop).

3 errorsThe compiler is telling you exactly what the problems are:
public int insert(int id, int numberInStock, int quality, double basePrice, String nm)//insert method
if(numberOfToolItems >= toolArray.length)
return 0; // <<== HERE you return, so everyting in the if block after this is unreachable
int index;
index = search(id); //< -----------------------------------------------------------------------------------------------------------------HERE
if (index == -1)
toolArray[index].assign(id,numberInStock, quality, basePrice,nm);
numberInStock ++;
return 1;
}//end if index
}//end if toolitem array
return -1;
}//end insert method
public int delete(/*int id*/)//delete method
// <<== HERE where is the return statement?
}//end delete method
public String getRecord(int i)//get record method
// return toolArray.getName()+ "ID: "+toolArray[i].getID() <<== HERE you commented out the return statement
}//end getrecod
}//end class

HT3523 hello, this is the error I get when I try to play a video QuickTime Player can't open "solea-antonio-walter.mov" because a required codec isn't available. Any idea what I need to do? thank you

Hello,
This is the error message I get when I try to watcha burnt dvd, can anyone tell me what I need to do?
thank you
QuickTime Player can't open "solea-antonio-walter.mov" because a required codec isn't available.

Quicktime X is a great little piece of software. However, Quicktime X is very finicky on which codec/file format it can decode/play.
Luckily, there are DOZENS of alternative video/media players and extensions available for the Mac. Some of them are even FREE. Some of the better FREE ones include...
PERIAN (quicktime extension)
http://www.macupdate.com/app/mac/22923/perian
QUICKTIME 7.6.6
http://support.apple.com/kb/DL923
VLC Media Player
http://www.macupdate.com/app/mac/5758/vlc-media-player
NICEPLAYER
http://www.macupdate.com/app/mac/15136/niceplayer
... And if none of those work, there is a possibility that, that video file may be corrupted.

This trigger giving mutation error? any body can tell why?

Hi All,
Could any body tell me where is the problem in my trigger.
my tables are.
1) EMP :- emp_id,emp_movement_status
2) EMPLOYEES_DAILY_MOVEMENT :- emp_id,transaction_time,transaction_remarks.
if i delete a entry from transactions_table, it has to take latest remarks from the maximum record after deletion of the record, then update EMP table accordingly.
trigger is:-
CREATE OR REPLACE TRIGGER change_employee_status AFTER INSERT OR UPDATE OR DELETE ON
employees_daily_movement FOR EACH ROW
DECLARE
local_remarks VARCHAR2(50);
BEGIN
IF DELETING THEN
SELECT transaction_remarks INTO local_remarks FROM employees_daily_movement WHERE
transaction_id = (SELECT MAX(transaction_id) FROM employees_daily_movement WHERE
emp_id = :old.emp_id );
/* here im expecting to take the TRANSACTION_REMARKS column value from employees_daily_movement after deleting the record which i wanted */
UPDATE emp SET emp_movement_status = local_remarks WHERE emp_id = :old.emp_id;
END IF;
END;
Thanks in advance

Hi Mr Rao,
You can handle muttating erros with following
1. Database version is oracle 9i and above, you can over come this problem for ever by using pragma autonomous_transaction.
2. Another way is, if you database version earlier to 9i then you can re-pharase this trigger by writting statement level trigger instead row level.
Cheers!!
Mahesh Ragineni

Isn't this Trigger code error prone?
