Can I change ORA-00001:unique constraint...?

hi,
I've table ST
NAME.........VARCHAR2(20)........PRIMARY KEY
ID..............NUMBER

INSERT INTO ST VALUES('PTS', 2);
INSERT INTO ST VALUES('PTS', 2);

I get (correctly) error ORA-00001:unique constraint (X_PK_Y) violated.

Can I change this message of error??

For example, can I get this error when I insert 2 primary key:

wrong: change your value please!



Thanks
Raf

First of all that is an Oracle system error.
Why would you want to change the text of the message?

Are you trying to provide a customized message to the end user?

Look at exception handling.
