I have the tables below in my database:
Student (Stud_no: string, Stud_name: string) Membership (Mem_no: string, Stud_no: string) Book (book_no: string,
Just write you query as:
AND iss_date >= '2019-08-06' AND iss_date < '2019-08-07'
Or more conveniently:
AND iss_date >= '2019-08-06' AND iss_date < '2019-08-06' + INTERVAL 1 DAY
While this looks lengthy, it can use indexes more efficiently and very generic.
