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 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 Curso

normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception sqlerrm line number handling lets you bulletproof your program so that it can continue operating in the presence of errors.

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/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 writ
Functions PSOUG Forum Oracle Blogs Search the Reference Library pages: FreeOracle MagazineSubscriptionsand Oracle White Papers Oracle Exception Handling Version 11.1 General NOTE: How Oracle Does Implicit Rollbacks Before executing an INSERT, UPDATE, or DELETE statement, Oracle marks an implicit savepoint (unavailable http://psoug.org/reference/exception_handling.html to you). If the statement fails, Oracle rolls back to the savepoint. Normally, just the failed http://www.java2s.com/Tutorial/Oracle/0480__PL-SQL-Programming/Errormessagecodeandtext.htm SQL statement is rolled back, not the whole 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. 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 oracle sql 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 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 print error code 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 first row I inserted 'manually', the one with a1 = 1. So there seems to have been an invisible savepoint set just before the unnamed block ran. CASE 2: Then I modified the unnamed block so it did two good inserts and then called a stored procedure that did two good inserts and ended with one 'bad' - inserting a character into a number column.
