Answer / anil kumar prajapati

The DUAL is special one row, one column table present by
default in all Oracle databases. The owner of DUAL is SYS
(SYS owns the data dictionary, therefore DUAL is part of the
data dictionary.) but DUAL can be accessed by every user.
The table has a single VARCHAR2(1) column called DUMMY that
has a value of 'X'. MySQL allows DUAL to be specified as a
table in queries that do not need data from any tables. In
SQL Server DUAL table does not exist, but you could create
one.
The DUAL table was created by Charles Weiss of Oracle
corporation to provide a table for joining in internal
views.
Example
Select Row r
From dual
Connect By Row <= :100
