Pl Sql Insert Error Exception
Contents |
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many pl sql exception handling examples other sources. Although you cannot anticipate all possible errors, you oracle raise exception with message can plan to handle certain kinds of errors meaningful to your PL/SQL program. With many programming pl sql exception handling best practices languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the oracle insert exception handling operating system. With PL/SQL, 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

What is the WHEN https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm OTHERS clause in Oracle? The WHEN OTHERS clause is used to trap all remaining exceptions that have not been handled by your Named System Exceptions and Named Programmer-Defined Exceptions. Syntax We will take a look at the syntax for the WHEN OTHERS clause in both procedures and functions. Syntax for Procedures The syntax for the WHEN OTHERS clause in a procedure is: CREATE [OR REPLACE] https://www.techonthenet.com/oracle/exceptions/when_others.php PROCEDURE procedure_name [ (parameter [,parameter]) ] IS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; Syntax for Functions The syntax for the WHEN OTHERS clause in a function is: CREATE [OR REPLACE] FUNCTION function_name [ (parameter [,parameter]) ] RETURN return_datatype IS | AS [declaration_section] BEGIN executable_section EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [function_name]; Example Here is an example of a procedure that uses a WHEN OTHERS clause: CREATE OR REPLACE PROCEDURE add_new_order (order_id_in IN NUMBER, sales_in IN NUMBER) IS no_sales EXCEPTION; BEGIN IF sales_in = 0 THEN RAISE no_sales; ELSE INSERT INTO orders (order_id, total_sales ) VALUES ( order_id_in, sales_in ); END IF; EXCEPTION WHEN DUP_VAL_ON_INDEX THEN raise_application_error (-20001,'You have tried to insert a duplicate order_id.'); WHEN no_sales THEN raise_application_error (-20001,'You must have sales in order to submit the order.'); WHEN OTHERS THEN raise_application_error (-20002,'An error has occurred inserting an order.'); END; In this example, if an exception is encountered that is not a DUP_VAL_ON_INDEX or a no_sales, it will be trapped by the WHEN OTHERS clause.

What is a named system exception in Oracle? Named system exceptions are exceptions that have been given names by PL/SQL. They are named in the STANDARD package in PL/SQL and do not pl sql exception need to be defined by the programmer. Oracle has a standard set of exceptions already named as follows: Oracle Exception Name Oracle Error Explanation DUP_VAL_ON_INDEX ORA-00001 You tried to execute an INSERT or UPDATE statement that has created a duplicate value in a field restricted by a unique index. TIMEOUT_ON_RESOURCE ORA-00051 You were waiting for a resource and you timed out. TRANSACTION_BACKED_OUT ORA-00061 The remote portion of a transaction has rolled back. INVALID_CURSOR ORA-01001 You tried to reference a cursor that does not yet exist. This may have happened because you've executed a FETCH cursor or CLOSE cursor before OPENing the cursor. NOT_LOGGED_ON ORA-01012 You tried to execute a call to Oracle before logging in. LOGIN_DENIED ORA-01017 You tried to log into Oracle with an invalid username/password combination.
