For this Question: Display the acceptance rate of requests defined as the ratio of accepted contacts vs all contacts. Multiply the ratio by 100 to get the rate.DataFrame/SQL Table with the following schema -
<schema>[{'name': 'airbnb_contacts', 'columns': [{'name': 'id_guest', 'type': 'object'}, {'name': 'id_host', 'type': 'object'}, {'name': 'id_listing', 'type': 'object'}, {'name': 'ts_contact_at', 'type': 'datetime64[ns]'}, {'name': 'ts_reply_at', 'type': 'datetime64[ns]'}, {'name': 'ts_accepted_at', 'type': 'datetime64[ns]'}, {'name': 'ts_booking_at', 'type': 'datetime64[ns]'}, {'name': 'ds_checkin', 'type': 'datetime64[ns]'}, {'name': 'ds_checkout', 'type': 'datetime64[ns]'}, {'name': 'n_guests', 'type': 'int64'}, {'name': 'n_messages', 'type': 'int64'}]}]</schema>Each row in a new line and each value of a row separated by a |, i.e.,
0|1|2
1|2|3
2|3|4-, I have written this Solution Code: SELECT 100.0*SUM(CASE
                     WHEN ts_accepted_at == 'NaT' THEN 1
                     ELSE 0
                 END)/COUNT(*) acceptance_rate
FROM airbnb_contacts, In this Programming Language: SQL, Now tell me if this Code is compilable or not?
