Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although sqlerrm in pl/sql you cannot anticipate all possible errors, you can plan to pl sql sqlcode handle certain kinds of errors meaningful to your PL/SQL program. With many programming languages, unless you oracle sql error code disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, sqlerror a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. This chapter discusses the following topics: Overview of PL/SQL Error Handling Advantages of PL/SQL Exceptions Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate

Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Error Handling In PL/SQL, a warning or error condition is called an exception. Exceptions can be internally defined (by the run-time 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 rais

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 exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment.

SHOW ERRORS http://www.java2s.com/Tutorial/Oracle/0480__PL-SQL-Programming/Errormessagecodeandtext.htm tips Expert Oracle Database Tips by Burleson Consulting December 13, 2015 Question: How does the PL/SQL show errors command work?Answer: When you run PL/SQL the code oracle sql is interpreted at runtime, and you may see these types of errors: Syntax errors: These are indicated by the "Warning: Procedure created with compilation errors" message. You can display the error with the "show errors" SQL*Plus command). Semantic errors: These are invalid table or column names. Run time errors: This is pl sql display a a non-zero Oracle database error code. For more details, see my notes on PL/SQL debugging techniques. Show errors command To see PL/SQL interpreter errors, you can use the SQL*Plus "show errors" command: as seen in the "show errors" example SQL> create or replace procedure example_defaults 2 (n_1 in number := 5, 3 n_2 in number := 6, 4 n_3 in number := 7) 5 as 6 begin 7 n_1 := n_2 + n_3; 8 end; 9 / Warning: Procedure created with compilation errors.
