To check if a field contains lowercase letters, you can use the Hive built-in function LOWER() combined with the REGEXP function.

For example, you can use the following statement to check if a field contains lowercase letters:

SELECT col_name
FROM table_name
WHERE REGEXP(col_name, '[a-z]')

This will return records containing lowercase letters.
