Solution 1

The query you're looking for would look something like this:

SELECT MONTH(bill_date) AS month, MIN(total_units) AS minimum_units
FROM bill
GROUP BY MONTH(bill_date);

Here's what this query does, step by step:

  1. SELECT MONTH(bill_date) AS month: This part of the query selects the month part of the date in the bill_date column and gives it an alias of month.

  2. MIN(total_units) AS minimum_units: This part of the query selects the minimum value in the total_units column for each group and gives it an alias of minimum_units.

  3. FROM bill: This part of the query specifies the table we're selecting data from, which is the bill table.

  4. GROUP BY MONTH(bill_date): This part of the query groups the selected data by the month part of the bill_date, which allows us to find the minimum total_units for each month.

Please replace bill_date and total_units with your actual column names if they are different.

Solution 2

Here is the SQL query you need:

SELECT MONTH(bill_date) AS month, MIN(total_units) AS minimum_units
FROM bill
GROUP BY MONTH(bill_date);

This query works as follows:

  1. SELECT MONTH(bill_date) AS month: This part of the query is selecting the month part of the date from the bill_date column and giving it an alias of month.

  2. MIN(total_units) AS minimum_units: This part of the query is selecting the minimum value from the total_units column for each group and giving it an alias of minimum_units.

  3. FROM bill: This part of the query specifies the table from which to select the data, which is the bill table in this case.

  4. GROUP BY MONTH(bill_date): This part of the query groups the selected data by the month part of the bill_date, which allows the MIN function to find the minimum total_units for each month.
