EXIT [SUCCESS | FAILURE | WARNING | n | variable | :BindVariable] Directs SQL*Plus to exit as soon as it detects a SQL command or PL/SQL block error (but after printing the error message). SQL*Plus will not exit on a SQL*Plus error. The EXIT clause of WHENEVER SQLERROR follows the same syntax as the EXIT command. See EXIT for more information. CONTINUE Turns comment in oracle sql script off the EXIT option. COMMIT Directs SQL*Plus to execute a COMMIT before exiting or continuing and save pending changes to the database. ROLLBACK Directs SQL*Plus to execute a ROLLBACK before exiting or continuing and abandon pending changes to the database. NONE Directs SQL*Plus to take no action before continuing. Usage The WHENEVER SQLERROR command is triggered by SQL command or PL/SQL block errors, and not by SQL*Plus command errors. Examples The commands in the following script cause iSQL*Plus to stop processing the current script and return focus to the Input area on the Workspace if the SQL UPDATE command fails: The commands in the following script cause SQL*Plus to exit and return the SQL error code if the SQL UPDATE command fails: WHENEVER SQLERROR EXIT SQL.SQLCODE UPDATE EMP_DETAILS_VIEW SET SALARY = SALARY*1.1; The following SQL command error causes iSQL*Plus to stop processing the current script and return focus to the Input area on the Workspace if the SELECT command fails: WHENEVER SQLERROR EXIT SQL.SQLCODE select column_does_not_exiSt from dual; select column_does_not_exist from dual * ERROR at line 1: ORA-00904: invalid column name Disconnected from Oracle.....

kinds of errors meaningful to your PL/SQL program. With many programming languages, unless you disable error checking, error handling in oracle stored procedure 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, a mechanism called exception handling lets https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12052.htm you "bulletproof" your program so that it can continue operating in the presence of errors.

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 excep

An exception can be either internally defined (by the run-time system) or user-defined. Examples of in oracle internally defined exceptions are ORA-22056 (value string is divided by zero) and ORA-27102 (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 your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to handling in oracle flag overdrawn bank accounts. 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 or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. 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. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; B
