Solution

Sure, here is the SQL query you asked for:

SELECT COUNT(*) AS count_total_units_500
FROM electricity_reading
WHERE total_units > 500;

This query works as follows:

  1. SELECT COUNT(*) AS count_total_units_500: This part of the query is used to count the number of rows in the result set and give it an alias name 'count_total_units_500'.

  2. FROM electricity_reading: This part of the query specifies the table from which to retrieve the data.

  3. WHERE total_units > 500: This is the condition that filters the data. It only selects the rows where the total_units per day is greater than 500.
