Yes, first I connect the as sysdba after that we insert
data in the dual table as
sql>conn / as sysdba
connected
sql>desc dual;
insert into dual values('A');
(1)row inserted
but I found some problems after that ,We use
sql> seelct * from dual;
Only one value displayed
that was default 'x' as system defined data not displayed
other data a like 'A'.
Dummy
