to your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such as sqlcode and sqlerrm example in oracle stack overflow or division by zero stops normal processing and oracle sqlcode list returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you bulletproof oracle sql codes list your program so that it can continue operating in the presence of errors.

Exceptions can be internally oracle sqlcode 942 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 exception handlers. After an exception handler runs, the current block stops executing and t

transaction. However, if the statement raises an unhandled exception, the host environment determines what is rolled back. If you exit a stored subprogram with an unhandled exception, PL/SQL does not assign values to OUT parameters. https://docs.oracle.com/cd/B19306_01/appdev.102/b14261/errors.htm Also, PL/SQL does not roll back database work done by the subprogram. At the level of the SQL*Plus prompt, every update/insert/delete has one implicit savepoint, and also the invocation of any unnamed block. Below that, the unnamed block itself has 'sub' savepoints - one foreach insert/update/delete statement in it, and one for each subprogram unit. And so on down the line. If an error occurs, and that error is handled http://psoug.org/reference/exception_handling.html at any level by the time we're back at the SQL*Plus prompt, we only rollback to the immediate savepoint at the start of the update/insert/delete that errors. Otherwise we rollback to the top-level 'virtual' savepoint currently in existence, which is my offending unnamed block. That is, a handled error is handled and so can be dealt with without rolling back all the way to the top. It is handled and the transaction proceeds. Commits define the end of a transaction (and start of a new one) - rollbacks only define the end of a transaction if they rollback to the last commit, rather than savepoint (whether explicit or implicit). I came to my 'version' from the following by no means exhaustive tests: CASE 1: I created a table a with one column, a1 number, and at the sqlplus prompt inserted a row with a1 = 1. I then ran that unnamed block I referred in an earlier post that, without an exception handler, does the following: INSERT INTO a VALUES (2); INSERT INTO a VALUES (3); INSERT INTO a VALUES ('a'); As expected I get an unhandled error on the last line. When I do a select for everything in the table a, I get the f

What does the SQLCODE Function do? The SQLCODE function returns the error number 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 SQLCODE function in Oracle/PLSQL is: SQLCODE pl sql error Parameters or Arguments There are no parameters or arguments for the SQLCODE function. Note See also the SQLERRM 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 SQLCODE 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 SQLCODE 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: SQLERRM 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.

So applications were written according this feature. Now I need to log errors in p1. But it shouldn't affect applications that use this procedure. Something like this: procedure p1 is begin bla bla bla; exception when others then log_error(sqlcode, sqlerrm); raise_new_exception (sqlcode, sqlerrm); end; In case of raise_application_error first parameter should be in range [-20000, -20999]. So if there raises exception no_data_found, it cannot raise this error. In case of exception_init, second parameter should not be variable. It must be numeric literal.
