Dual table is a sample permanent table which come along with
oracle.
for example if u want to knw the sin(45) value then u have
to retreave it from a table.but there is no table to
retreave that value.
so we use the sample table dual as table name in place of
table name in the select query.
ex:select sin(45) from dual;
