How to find rows that have a value that contains a lowercase letter

I'm looking for an SQL query that gives me all rows where ColumnX contains any lowercase letter (e.g. "1234aaaa5789"). Same for uppercase.

Answer
SELECT * FROM my_table 
WHERE UPPER(some_field) != some_field

This should work with funny characters like åäöøüæï. You might need to use a language-specific utf-8 collation for the table.
