The previous post told you how to use decode which is fine for versions 8 and
lower, but if have 8.1 you can use the SQL CASE statement like this:
UT1> SELECT CASE WHEN rownum > 07 THEN 'big time'
2 WHEN rownum < 04 THEN 'small fry' 3 ELSE 'middle management' END as "CASE WHEN"4 FROM all_tables
CASE WHEN
9 rows selected.
