Cant figure this out, tried many other ways already please help

Challenge Task 3 of 4 In a car database there is a Sale table with columns, SaleID, CarID, CustomerID, LocationID, SalesRepID, SaleAmount and SaleDate and a Customer table with columns, CustomerID, FirstName, LastName, Gender and SSN.

Use a subquery along with IN to list all sales to female customers. (Gender = 'F') Select all columns.

To facilitate a rapid and accurate answer:

  • select the correct category for the course (probably "Databases" here)
  • show the entire query you were trying
  • provide a link to the course page you are working with

That's good, but a link to the page's URL would be better. And also show the query that you were trying that was giving you trouble.

Plus, remember to edit the question to set the same category as the course.
