sometime it is required to spool sql output to excel file, i learned a new way to do this and it is very simple and handy. just posing an example below, this was told to me by one on my friends who is a dba and i have also seen such examples on otn website as well.
you just need to connect to sqlplus and use following :-
SQL>set markup html on;
SQL>select empno,deptno from scott.emp;
SQL> SPOOL OFF;
SQL> SET MARKUP HTML OFF;
Its an easy way...
