CREATE TABLE table_name_66 (number_of_hus__approximate_ VARCHAR, digits VARCHAR, level VARCHAR)

What's the approximate number of HUs when there are more than 2 digits, and 6 levels?
SELECT COUNT(number_of_hus__approximate_) FROM table_name_66 WHERE digits > 2 AND level = 6
SELECT COUNT("number_of_hus__approximate_") FROM "table_name_66" WHERE "digits" > 2 AND "level" = 6
