The data sometimes is corrupted and the

process fails but in these cases I need just ignore the exceptions and continue because it is not important to catch the error. How can I write the exception clause to just go on without raising any error when an exception ocurrs? I've tried just leaving the clause empty: ... EXCEPTION WHEN OTHERS THEN end test_trigger; but it does not compile. What am I missing? there is some "pass" clause that I should be including? oracle plsql triggers share|improve this exception handling in oracle stored procedure example question asked Aug 18 '09 at 20:51 Sam 1,89142240 8 "WHEN OTHERS THEN {do nothing}" is a very bad idea. Any error might occur (including some errors that you might want to know about) and you'll never know. You may as well save time and not have the precalc columns set at all. You should work out what kinds of exceptions might occur in the normal course of work and handle them explicitly. –Jeffrey Kemp Aug 20 '09 at 11:52 add a comment| 1 Answer 1 active oldest votes up vote 26 down vote accepted ...

I have a procedure, where in I drop partitions https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:1155066278457 every day and add partitions. My question is about the exception section. Do I have to give specific exception conditions to handle the erros which are possible while dropping and adding partitions, or should I leave it by just giving the when others then exception, or should I leave it alone by not giving the exception section at all. what are the possible erros which can occur while trying to create a partition and trying to drop a partition. 2. The pl sql use of pragma exception init is very clear, but Why do you have to use a raise application error. Can I just use a regular exception, and raise it when I require to. I dont see the specific use of raise application error. what is the advantage of raise application error over a regular exception which you declare in the exception section and use it. (the only advantage seems to be that you can assign a number(20001 to 20999) to the error.) oracle trigger ignore correct me if Iam wrong. and we said... 1) A when others is almost always a BUG unless it is immediately followed by a RAISE. The point of an exception block is to catch exceptional conditions you are EXPECTING, handle them gracefully and continue. For example, lets say you have a procedure that will either INSERT a new record or UPDATE an existing one depending on whether or not it exists. You could code: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; end; Now, if that was coded: begin insert into t ( columns.... ) values ( values ..... ); exception when dup_val_on_index then -- record already exists, lets update it update t set .... = .... where ....; when others then null; end; that would be a bug. The when others would fire upon some spurious -- un-expected error and the record would be neither added nor updated. It would be skipped. Same with your routines, if you have a when others -- and don't do anything meaningful in it (eg: email yourself a notification that it failed, log a message using utl_file or an autonomous transaction, etc -- it is an error that will go undetected. I truly wish we didn't even support WHEN OTHERS. You should only catch the exceptions you are expecting and can do s
