I have a table emp. There is only one column in the table.
In that , there are only three rows in that column.
The value in the first row is 'A' and the value in the
second row is 'B' and the third row is 'C'. Now, my question
is ,
How will you write a select query to display the output as
B
C
A
Note: order by cannot be used coz it gives us output as CBA.
But the output should be BCA.
