im doing some practice sql problems
one of the questions is:
Prepare a shipping statement for
customer ‘C001’ it should show the
date, the legend ‘Delivery’ and the
total value of the products shipped on
each day.
‘delivery’ is not a table nor is it a column in any table.
what does legend mean??
It doesn’t mean anything in SQL. In English it means the label at the top of the column or next to the data that explains what the data is.
In other words, produce a listing showing the customer number, the date, and a column labeled “Delivery” that shows the total value of goods shipped to that customer on that date.
