Answer 1

UPDATE tablesubtype
   SET SUBTYPES  = TRIM (SUBTYPES);Doing RTRIM alone will not suffice coz it'll only remove Right Spaces and NOT Left ones.
I guess, in your case doing a TRIM will be more beneficial to be safe and prevent any left spaces in future.
For intermediate spaces... try this.
UPDATE tablesubtype
   SET SUBTYPES  = REGEXP_REPLACE (SUBTYPES, ' ', '');Hope this Helps,
