write absolutely perfect PL/SQL programs, it is possible and even likely that something will go wrong and an error will occur when those programs are run. How your https://docs.oracle.com/cd/E23507_01/Platform.20073/PageDevGuide/html/s0704formerrorhandling01.html code responds to and deals with that error often spells the difference between a successful application and one that creates all sorts of problems for users as well as developers. This article explores the world of error management in PL/SQL: the different types of exceptions you may encounter; when, why, and how exceptions are raised; how to define http://www.oracle.com/technetwork/issue-archive/2012/12-mar/o22plsql-1518275.html your own exceptions; how you can handle exceptions when they occur; and how you can report information about problems back to your users. Exception Overview There are three categories of exceptions in the world of PL/SQL: internally defined, predefined, and user-defined. An internally defined exception is one that is raised internally by an Oracle Database process; this kind of exception always has an error code but does not have a name unless it is assigned one by PL/SQL or your own code. An example of an internally defined exception is ORA-00060 (deadlock detected while waiting for resource). A predefined exception is an internally defined exception that is assigned a name by PL/SQL. Most predefined exceptions are defined in the STANDARD package (a package provided by Oracle Database that defines many common programming elements of the PL/SQL language) and are among the most commonly encountered exceptions. One example is ORA-00001, which is assigned the name DUP_VAL_ON_INDEX in PL/SQL and is raised when a unique index constraint is violated. A user-defined ex
