Do you want to know:
- if there are lower case characters?
- what are the lower case characters?
- how many lower case characters?
- how many for each lower case character?
- where (at which indices) are the lower case characters?
...

Regards
Michel

just use SUBSTR to get the last character, and then check if last_character = UPPER(last_character).
If it does, then it was upper case.

Do enlighten me. How do you use the length function to determine the case of the last character of a string - other than by using some other function to actually modify the data, and using length to check the result of that?

substr gives you the last character, comparing it with its lower value will give you if it is upper or lower case.

--If the string is saved in a column (say 'col1' in table 'tab1' then you can use:
select col1 from tab1 where regexp_like(col1, '[a-z]');

It's great that you learned how to use regular expressions, but this has nothing to do with question, and 3 years later no less.
