how to use the Oracle/PLSQL SQLERRM function with syntax and examples. 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 sqlerrm length 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.

Burleson Consulting March 3, 2015 Question: What does the PL/SQL raise_application_error code do? Answer: The raise_application_error is actually a procedure oracle raise exception with message defined by Oracle that allows the developer to raise an exception and associate an error number and message with the procedure. This allows the application to raise application errors rather than just Oracle https://www.techonthenet.com/oracle/exceptions/sqlerrm.php errors. Error numbers are defined between -20,000 and -20,999. Oracle provides the raise_application_error procedure to allow you to raise custom error numbers within your applications. You can generate errors and their associated text starting with -20000 and proceeding through -20999 (a grand total of 1,000 error numbers that you can use). Below we illustrate the use of the raise_application_error procedure. Using the raise_application_error procedure: DECLARE Balance integer := http://www.dba-oracle.com/t_raise_application_error.htm 24; BEGIN IF (nBalance <= 100) THEN Raise_Application_Error (-20343, 'The balance is too low.');END IF;END; In this example, error number -20343 is raised if the value of nBalance isn't greater than 100, yielding a message that looks like this: ORA-20343: The balance is too low. All other numbers belong to Oracle for its own errors. The message can be anything that will fit in a varchar2(2000). The final parameter passed to the procedure is a Boolean(true/false) that tells the procedure to add this error to the error stack or replace all errors in the stack with this error. Passing the value of 'True' adds the error to the current stack, while the default is 'False'.

comments Tweet One of the first things I noticed when making an APEX application, there was a lack of error handling. In particular, the error handling raised from an database procedure. For clarity, here a part of a screen as you will see after a unique constraint violation, the ORA-0001 error. I think the most horrible part is that this error is displayed on a new page! Errors like these must be displayed on the same page where the error occured, on top of the page, in the #NOTIFICATION_MESSAGE# area, the same way as page processing validation is displayed. Here a preview of the final result. This of course can be achieved by adding an extra page process validation. Page process validation is to be conducted before the page procesess. Major disadvantage of this solution is that all business rules which are implemented in the database, must be defined as a page process validation on each APEX page. Moreover, if we adding a business rule on the database, we must not forget to add an extra process validation on a ore more APEX pages. Make sure that all errors are handled by one procedure (a good habit anyway). something like this: exception when others then omp_log.error(sqlcode,sqlerrm); end ins; In this procedure, we test of this error has occurred in an APEX environment. If so, we DON'T raise this as a application error. Moreover, we remember through a package variable that an error has occurred which had not been raised. if v('APP_SESSION') is null then pv_set_unraised_error_exists := false; raise_application_error(sqlcode,sqlerrm); else -- context is APEX pv_set_unraised_error_exists := true; -- save the omp_nos.ins(sqlerrm); end if; We also save the error occurred in a temporary table. We must do that with an autonomous transaction so that the errors are actually recorded in the temporary table. We can not keep these errors in a package pl/sql table because the web, and therfore APEX is stateless and everytime we (re-)load an APEX page, we have got an new oracle session. create global temporary table omp_notifications ( session_id number not null enable ,text varchar2(4000 byte) not null enable ) on commit preserve rows ; create or replace package body omp_nos as procedure ins(p_sqlerrm in var
