program. With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division user defined exception in pl sql by zero stops normal processing and returns control to the operating system.

Pl/sql Raises An Exception In Which Two Of The Following Cases
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 exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control

As you asked, my script will contain Update and Insert. for example, I may have 10-15 udpate queries and same amont of insert queries in same script file. Now I need to spool the result of each line of my script. is it possible? –Sabari Ram Mar 10 '1

A user runs a DDL statement such as CREATE, DROP, RENAME, or ALTER. If the current transaction contains any DML statements, Oracle first commits the transaction, and then runs and commits the DDL statement as a new, single statement transaction. A user disconnects from Oracle. The current transaction is committed. A user process terminates abnormally. The current transaction is rolled back. Am I to interpret the last point to mean that if I issue a query that has an error, the transaction will get rolled back? sql oracle transactions plsql oracle10g share|improve this question edited Sep 23 '09 at 19:36 OMG Ponies 199k37361417 asked Sep 23 '09 at 19:32 Jason Baker 79.9k81291465 Actually, it sounds like a very interesting question to me. Postgres rollsback on error, and I've often found it annoying (and wondered if Oracle did something similar). –jsight Sep 23 '09 at 19:35 Tell me, why are you using transactions if you don
