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 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..... The following examples show that the WHENEVER SQLERROR command is not executed after errors with SQL*Plus commands, but it is executed if SQL commands or PL/SQL blocks cause errors: WHENEVER SQLERROR EXIT SQL.SQLCODE column LAST_name headIing "Employee Name" Unknown COLUMN option "headiing" SHOW non_existed_o
Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many oracle sqlcode other sources. Although you cannot anticipate all possible errors, you

can plan to handle certain kinds of errors meaningful to your PL/SQL program. With many programming sql error 803 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 https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12052.htm 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 https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm 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 exce

The following topics are covered: Understanding exceptions Trapping exceptions https://docs.oracle.com/cd/E11882_01/timesten.112/e21639/exceptions.htm Showing errors in ttIsql Differences in TimesTen: exception handing and error behavior Understanding exceptions This section provides an overview of exceptions in PL/SQL programming, covering the following topics: About exceptions Exception types http://stackoverflow.com/questions/11197088/how-do-i-exit-a-script-in-sqlplus-when-an-error-occurs-and-return-to-the-sqlplus About exceptions An exception is a PL/SQL error that is raised during program execution, either implicitly by TimesTen or explicitly by your program. Handle an exception by trapping it with a handler sql error or propagating it to the calling environment. For example, if your SELECT statement returns multiple rows, TimesTen returns an error (exception) at runtime. As the following example shows, you would see TimesTen error 8507, then the associated ORA error message. (ORA messages, originally defined for Oracle Database, are similarly implemented by TimesTen.) Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name whenever sqlerror exit INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > END; > / 8507: ORA-01422: exact fetch returns more than requested number of rows 8507: ORA-06512: at line 4 The command failed. You can handle such exceptions in your PL/SQL block so that your program completes successfully. For example: Command> DECLARE > v_lname VARCHAR2 (15); > BEGIN > SELECT last_name INTO v_lname > FROM employees > WHERE first_name = 'John'; > DBMS_OUTPUT.PUT_LINE ('Last name is :' || v_lname); > EXCEPTION > WHEN TOO_MANY_ROWS THEN > DBMS_OUTPUT.PUT_LINE (' Your SELECT statement retrieved multiple > rows. Consider using a cursor.'); > END; > / Your SELECT statement retrieved multiple rows. Consider using a cursor. PL/SQL procedure successfully completed. Exception types There are three types of exceptions: Predefined exceptions are error conditions that are defined by PL/SQL. Non-predefined exceptions include any standard TimesTen errors. User-defined exceptions are exceptions specific to your application. In TimesTen, these three types of exceptions are used in the same way as in Oracle Database.

I need a way to exit the script when an error occurs, without disconnecting or exiting SQLPlus itself. 100% of the time, when an error occurs, the connected DBA will need to issue one or more commands into the session. 100% of the time, when an error occurs, there are other SQLPlus statements (and thus must be outside of a BEGIN..END;) later on in the script that must not be executed or serious problems could arise. NOTE: If you suggest WHENEVER SQLERROR EXIT then you didn't read the above text. That will disconnect and exit SQLPlus in addition to the script, which is not acceptable behavior. oracle sqlplus share|improve this question asked Jun 25 '12 at 20:45 Thought 4521717 1 Of of interest why don't you split your scripts up into a shell / batch script and use whenever sqlerror exit and then the shell script error-handling to decide whether to continue? –Ben Jun 26 '12 at 8:32 Because there are a bunch of manual stuff that they'll want to do before and/or after the script runs, including running other scripts, that are specific to the situation / environment / data / etc. involved. This is primarily for fixing things in production, and constantly being kicked out / having to reconnect is worse than a
