Accomplish the following exercise and copy/paste the results into your week 10 assignment submission Word document.

Using ch10_abc_markets database, write the MySQL code to select the invoice year from inv_date with the column name invoiceYear, the invoice month from inv_date with the column name invoiceMonth, the invoice day from inv_date with the column name invoiceDay, and the sum of the invoice total with the column name invoiceTotal from the invoice table.

Group the results by year, month, and day using the ROLLUP subclause.
