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 you "bulletproof" oracle sqlerrm 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 whenever sqlerror exit 1 shell script 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 raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routines called exception handlers. After an exceptio

SQL command or PL/SQL block error (but after printing the error message). SQL*Plus will not exit on a SQL*Plus error. EXIT [SUCCESS | FAILURE | WARNING https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/07_errs.htm | 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 https://docs.oracle.com/database/121/SQPUG/ch_twelve052.htm 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 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

What does the SQLERRM Function do? The SQLERRM function returns the error message associated with the most recently raised error exception. This function should only be used within the Exception Handling section of your code. Syntax The syntax for the SQLERRM function in Oracle/PLSQL is: SQLERRM whenever sqlerror exit Parameters or Arguments There are no parameters or arguments for the SQLERRM function. Note See also the SQLCODE function. Example Since EXCEPTION HANDLING is usually written with the following syntax: EXCEPTION WHEN exception_name1 THEN [statements] WHEN exception_name2 THEN [statements] WHEN exception_name_n THEN [statements] WHEN OTHERS THEN [statements] END [procedure_name]; You could use the SQLERRM function to raise an error as follows: EXCEPTION WHEN OTHERS THEN raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM); END; Or you could log the error to a table using the SQLERRM function as follows: EXCEPTION WHEN OTHERS THEN err_code := SQLCODE; err_msg := SUBSTR(SQLERRM, 1, 200); INSERT INTO audit_table (error_number, error_message) VALUES (err_code, err_msg); END; NEXT: Declare Cursor Share this page: Advertisement Back to top Home | About Us | Contact Us | Testimonials | Donate While using this site, you agree to have read and accepted our Terms of Service and Privacy Policy.
