minute: Sign up Exit execution when error occurs PL/SQL up vote 3 down vote favorite I would like to know, how can I exit the execution when an error occurs. In Microsoft SQL Server there is a RETURN clause, which does the work. But I would like to know similar functionality in Oracle. I am using Oracle Sql Developer. Here is

the script I am using: First block throws error due to Unique Key Violation, even though it throws error the execution goes to next block and executes the insert statement. I want to end the execution or exit at first block of code itself. Please help me to write the code. First anonymous PL/SQL block: set serveroutput on; BEGIN insert into test values(1); insert into test values(1); COMMIT; dbms_output.put_line('PRINT SOMETHING 1'); EXCEPTION WHEN OTHERS THEN if sqlcode <> 0 then dbms_output.put_line(SQLCODE || ' ' || SQLERRM); RAISE; end if; return; END; / Second anonymous PL/SQL block: set serveroutput on; BEGIN insert into test values(6); COMMIT; dbms_output.put_line('PRINT SOMETHING'); EXCEPTION WHEN OTHERS THEN if sqlcode <> 0 then dbms_output.put_line(SQLCODE || ' ' || SQLERRM); RAISE; end if; return; END; / oracle execution share|improve this question edited Feb 14 '14 at 18:30 Nicholas Krasnov 19.2k42849 asked Feb 14 '14 at 18:23 user3311382 1612 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote If you create a stored procedure, you have more control and can exit whenever you like with a retur

possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. pl/sql raise exception With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns http://stackoverflow.com/questions/21786763/exit-execution-when-error-occurs-pl-sql control to the 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 contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of Predefined PL/SQL Exceptions Defining Your Own PL/SQL https://docs.oracle.com/cd/B13789_01/appdev.101/b10807/07_errs.htm 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 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
class="underline">COMMIT | ROLLBACK] | CONTINUE [COMMIT | ROLLBACK | NONE]} Performs the specified action (exits SQL*Plus by default) if a SQL command or PL/SQL block generates an error. Terms [SUCCESS | FAILURE | WARNING https://docs.oracle.com/database/121/SQPUG/ch_twelve052.htm | n | variable | :BindVariable] Directs SQL*Plus to perform the specified action as soon as it detects a SQL command or PL/SQL block error (but after printing the error message). https://www.tutorialspoint.com/plsql/plsql_exit_statement.htm SQL*Plus will not exit on a SQL*Plus error. EXIT [SUCCESS | FAILURE | WARNING | n | variable | :BindVariable] Directs SQL*Plus to exit as soon as it detects a SQL pl 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 pl sql exit 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 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 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_option The following PL/SQL block error causes SQL*Plus to exit and return the SQL error code: WHENEVER SQLERROR EXIT SQL.SQLCODE begin SELECT COLUMN_DOES_NOT_EXIST FROM DUAL; END; / SELECT COLUMN_DOES_NOT_EXIST FROM DUAL; * ERROR at line 2: ORA-06550: line 2, column 10: PLS-00201: identifier 'COLUMN_DOES_NOT_EXIST' must be declared ORA-06550: line 2, column 3: PL/SQL: SQL Statement ignored Disconnected from O

If you are using nested loops (i.e. one loop inside another loop), the EXIT statement will stop the execution of the innermost loop and start executing the next line of code after the block. Syntax: The syntax for an EXIT statement in PL/SQL is as follows: EXIT; Flow Diagram: Example: DECLARE a number(2) := 10; BEGIN -- while loop execution WHILE a < 20 LOOP dbms_output.put_line ('value of a: ' || a); a := a + 1; IF a > 15 THEN -- terminate the loop using the exit statement EXIT; END IF; END LOOP; END; / When the above code is executed at SQL prompt, it produces the following result: value of a: 10 value of a: 11 value of a: 12 value of a: 13 value of a: 14 value of a: 15 PL/SQL procedure successfully completed. The EXIT WHEN Statement The EXIT-WHEN statement allows the condition in the WHEN clause to be evaluated. If the condition is true, the loop completes and control passes to the statement immediately after END LOOP. Following are two important aspects for the EXIT WHEN statement: Until the condition is true, the EXIT-WHEN statement acts like a NULL statement, except for evaluating the condition, and does not terminate the loop. A statement inside the loop must change the value of the condition. Syntax: The syntax for an EXIT WHEN statement in PL/SQL is as follows: EXIT WHEN condition; The EXIT WHEN statement replaces a conditional statement like if-then used with the EXIT statement. Example: DECLARE a number(2) := 10; BEGIN -- while loop e
