Courses Plus Student 2,650 PointsDate Formatting for all date columns
-- The loans table has the following ids columns: id, book_id, patron_id; and the following date columns: loaned_on, return_by, returned_on; -- Format dates in all the loans table in the UK format without the year. For example, April 1st is 01/04.

230,274 PointsAre you asking about how to format dates?
There's a function for doing that, called strftime. The first argument is a string that defines the format the date will be displayed with, and the second argument is the date to be formatted.
See the SQLite documentation for a list of the possible formatting codes.

Courses Plus Student 2,650 PointsSELECT STRFTIME("%d/%m", loaned_on) AS uk_loaned_on, STRFTIME("%d/%m", return_by) AS uk_return_by, STRFTIME("%d/%M", returned_on) AS uk_returned_on FROM loans;
I was trying all 3 columns in ONLY one STRFTIME function yesterday. I didn't know you could put in more than one STRFTIME function.

Courses Plus Student 2,650 PointsMy question is about modifying dates for all columns without using the STRFTIME function which only adds another column.
How would you format dates for all columns without using the STRFTIME column to complete the above objective?
