Loans Due solution

Hi,

The Loans Due practice question was nice. I've researched and came up with this:

SELECT * FROM loans WHERE return_by BETWEEN DATE('now', 'weekday 0', '-6 days') AND DATE('now', 'weekday 0') AND returned_on IS null;

Did anybody found a cleaner/more compact solution? :)

Cheers!

Hi this is my solution SELECT * FROM loans WHERE STRFTIME("%W", return_by) = STRFTIME("%W", "now") AND returned_on IS NULL;

SELECT * FROM loans WHERE return_by BETWEEN DATE("now") AND DATE("now", "+7 days") AND returned_on IS NULL;

I believe I have the most compact code!

SELECT * FROM loans WHERE STRFTIME("%w", return_by) AND returned_on IS NULL (optional)

Surprisingly was one of my first attempts at the question :)

This is how I wrote it: SELECT * FROM loans WHERE return_by BETWEEN DATE("now", "-1 day") AND DATE("now", "+6 days") AND returned_on IS NULL;

When I completed this it was the week of 02/13/17 through 02/19/17 and the day I completed it on was 02/14/17.
