20. The Repairs Table

Instruction

For the purpose of this short quiz, we'll use a new table: Repairs.

Exercise

Select all the information from the Repairs table.

Our phone repair workshop stores statistics in the Repairs table. Look at the information in this table. Each row contains:

  • the Phone name,
  • the Day,
  • the number of FreeRepairs performed (under warranty),
  • the number of PaidRepairs performed on that day,
  • the Revenue generated by the paid repairs.
