-- SELECT TRANSLATE(SUBSTR('venkat',1,4),
--                  'e0123456789',
--                  'R') from dual;
-- In the string -> SUBSTR('venkat',1,4) = 'venk'
-- Convert all occurrences of "e" to "R"
-- Convert all occurrences of "0" to ""  i.e. to NULL
-- Convert all occurrences of "1" to ""  i.e. to NULL
-- Convert all occurrences of "2" to ""  i.e. to NULL
-- Convert all occurrences of "3" to ""  i.e. to NULL
-- Convert all occurrences of "4" to ""  i.e. to NULL
-- Convert all occurrences of "5" to ""  i.e. to NULL
-- Convert all occurrences of "6" to ""  i.e. to NULL
-- Convert all occurrences of "7" to ""  i.e. to NULL
-- Convert all occurrences of "8" to ""  i.e. to NULL
-- Convert all occurrences of "9" to ""  i.e. to NULL
-- Let the other characters remain as they are
