How do I reverse a string with sql query only?

How do I reverse a string with sql query only?:confused:

try this
--------
select reverse('string')...

oracle : SELECT REVERSE('string') FROM dual;
SQL Server : SELECT REVERSE('string')

by using REVERSE we can reverse the string like
select reverse('string') from dual;

there is no sence posting such kind of questions here in the forum.

these are very much grass root level.
