Solution
Here is the SQL query that you can use to get the desired result:
SELECT m.meter_number, b.owner_name, b.address
FROM building b
JOIN meter m ON b.building_id = m.building_id
JOIN bill bi ON m.meter_id = bi.meter_id
GROUP BY m.meter_number, b.owner_name, b.address
ORDER BY COUNT(bi.fine_paid) DESC, b.owner_name ASC;
Here is the step by step explanation of the query:
-
SELECT m.meter_number, b.owner_name, b.address: This line is selecting the columns that you want to display in the result. -
FROM building b: This line is specifying thebuildingtable as the main table for the query. -
JOIN meter m ON b.building_id = m.building_id: This line is joining themetertable with thebuildingtable on thebuilding_idcolumn. -
JOIN bill bi ON m.meter_id = bi.meter_id: This line is joining thebilltable with themetertable on themeter_idcolumn. -
GROUP BY m.meter_number, b.owner_name, b.address: This line is grouping the result by themeter_number,owner_name, andaddresscolumns. -
ORDER BY COUNT(bi.fine_paid) DESC, b.owner_name ASC: This line is ordering the result by the number of times a fine was paid in descending order and then by theowner_namein ascending order.
Please replace the column and table names with the actual ones in your database.
