Re: Re[2]: Big Whoops

Ruth,

In my reply I cut out a snippet of the entire program to explain about machine names. The entire script must be run for this to work:

set heading off
set prompt off
spool make_prompt.sql
SELECT 'set sqlprompt '''|| d.name ||'@' || substr(s.machine,1,decode (instr(s.machine,'.'), 0, length(s.machine), instr(s.machine,'.') - 1)) ||
'-SQL> '''
FROM V$SESSION s, V$DATABASE D
WHERE s.SID=1;
spool off
@make_prompt.sql
set heading on
set feedback on
