I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The title uses "words" but the question uses "letters".  Which one do you want?

To see how many letters are in a string:  There are several ways.  Here is the one I would go with:
select length(words)-length(replace(words,'A')) from dual;

You can also do a regexp_count but for this, that is probably overkill.

If you want the number of words, we can to that as well depending on how you define a word.

If anything separated by spaces, similar replace and length check but you need to remove repeating spaces before doing it.

For words, I might look at regexp_count.
