Cool! We have a list of nice and cozy apartments. Let's take a look at the table that contains information about the lovely couples who want to rent one!


Select all data from the couples table.

As you can see, it has five columns:

  • id – the ID of a given couple,
  • couple_name – the name of a given couple (consists of the names of both partners),
  • min_price – the minimum starting price of the apartment that a given couple wants to take a look at.
  • max_price – the maximum price the couple is willing to pay for an apartment, and
  • pref_location – the location a given couple would be most interested in.

Stuck? Here's a hint!
