cannot anticipate all possible errors, you can plan to handle certain kinds oracle pl sql exception when others of errors meaningful to your PL/SQL program. With many programming languages, unless you disable error checking, a too_many_rows exception oracle pl sql run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you

PL/SQL Errors Overview of PL/SQL Compile-Time Warnings Overview of PL/SQL Runtime Error Handling In PL/SQL, an error condition is called an exception. Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines called exception handlers. After an e

hard enough—and more than enough work—to simply write the code that implements the positive aspects of an application: maintaining customers, pl sql exception handling best practices generating invoices, and so on. You write applications that often assume the best of all possible worlds, hoping that your programs are bug-free, that users will enter only the correct data in only https://docs.oracle.com/cd/B13789_01/appdev.101/b10807/07_errs.htm the correct fashion, and that all systems (hardware and software) will always be a "go." No matter how hard you try, there will always be one more bug in your application. And your users will always find just the right sequence of keystrokes it takes to make a screen implode. The reality is clear: Either you spend the time up front to properly debug and bulletproof http://www.oracle.com/technetwork/issue-archive/o33plsql-083386.html your programs, or you will fight an unending series of rear-guard battles, taking frantic calls from your users and putting out the fires. Fortunately, PL/SQL offers a powerful and flexible way to trap and handle errors in your programs. It is entirely feasible within the PL/SQL language to build an application that fully protects the user and the database from errors. And if you go about it correctly, you minimize the amount of code you need to write to get the job done. This article, the first of two parts, will explore a set of best practices you should follow to incorporate high-quality, comprehensive error handling in your PL/SQL-based applications. This article will start by considering some overall best practices for error handling and then focus on best practices relating to raising exceptions. The next article will move on to how best to handle exceptions. Set Guidelines before You Start Before you start writing any application code, you first need to decide on your overall strategy for error handling, as well as specific coding guidelines. There is no single strategy that works for all applications; you have to decide what makes the most sense for y
