Trapping system exceptions

[kalyson]

Hello,
I see that Oracle raises its own exceptions for things like this:

EXECUTE IMMEDIATE l_sql_stmt INTO l_temp_string;

when there is no data found from the query. I don't want to handle all these exceptions in one WHEN DATA_NOT_FOUND exception handler. I think it is incredible that these exceptions can not be differentiated! In Java, such errors can be captured inside a try/catch block. But not here, it seems....

I can do some nasty kludge, like setting a global variable to tell me which function I was in when the error occurred, but does anyone else have an idea?

Thanks,
Kris

Well, I think I see the answer myself. You can use enclosing local blocks and have a no_data_found exception handler there that raises another exception that throws it to the main block's exception handler.

Yes you need to handle those in local blocks because the execution of exception is from inner block to outer block.

I do not understand what you mean by "I think it is incredible that these exceptions can not be differentiated? ?". You can differentiate the exceptions in oracle.
