Chapter 15 DBMS-Specific Features
PL/SQL allows you to explicitly handle internal and user-defined error conditions, called exceptions, that arise during processing of PL/SQL code.
You can create user-defined exceptions linked to the database package behavior.
Exceptions have the following properties:
| Properties | Description |
|---|---|
| Name | The name of the item which should be clear and meaningful, and should convey the item's purpose to non-technical users. |
| Code | The technical name of the item used for generating code or scripts, which may be abbreviated, and should not generally include spaces. |
| Comment | Additional information about the exceptions. |
| DB Package | Name of the database package to which the exception belongs. |
| Pragma | Allows you to type a compiler directive, that is, a string for specifying compilation parameters for the exception. |
