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

Question

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 1

This is how I did it for utf8 encoded table and utf8_unicode_ci column, which doesn't seem to have been posted exactly:

SELECT *
FROM table
WHERE UPPER(column) != BINARY(column)
