oracle - How do I exit a script in SQLPlus when an error occurs and return to the SQLPlus prompt, without disconnecting or exiting SQLPlus?

Question

I have some scripts that get run often, always from within a connected SQLPlus session.

I need a way to exit the script when an error occurs, without disconnecting or exiting SQLPlus itself. 100% of the time, when an error occurs, the connected DBA will need to issue one or more commands into the session. 100% of the time, when an error occurs, there are other SQLPlus statements (and thus must be outside of a BEGIN..END;) later on in the script that must not be executed or serious problems could arise.

NOTE: If you suggest WHENEVER SQLERROR EXIT then you didn't read the above text. That will disconnect and exit SQLPlus in addition to the script, which is not acceptable behavior.

I've found an interesting idea here which, when combined with spencer7593's answer, will get me selective sub-script calling, to which I can pass the PL/SQL output values. To wit:

VAR continue number;
EXEC :continue := 1;
BEGIN
   SELECT some_bool_test() INTO :continue FROM dual;
END;

SET termout OFF
COLUMN script_name NEW_VALUE v_script_name
SELECT decode(:continue, 1, 'run_stuff.sql', 'skip.sql') script_name FROM dual;
SET termout ON

@&v_script_name :some_other_values

Where skip.sql is an empty text file.
 

UPDATE: I've moved most of this into a RUN.SQL file, where I pass in the boolean (0 or 1) as &1, the script name to call on success as &2, and then any other expected parameters to pass to the called script. Thus, it ends up looking something like this:

VAR continue number;
EXEC :continue := 1;
BEGIN
   SELECT some_bool_test() INTO :continue FROM dual;
END;

@run.sql :continue 'run_stuff.sql' :some_other_values
