Select rows for a specific date using TIMESTAMP datatype

Question

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,         


        

Answer 1

Note that we stopped writing queries this way ca. 1992. Come. Join us.

FWIW, I find this easier to read...

SELECT s.stud_name
     , b.book_name
     , b.author
     , r.iss_date
  FROM student s
  JOIN membership m
    ON m.stud_no = s.stud_no 
  JOIN iss_rec r 
    ON r.Mem_no = m.Mem_no 
  JOIN book b
    ON b.book_no = r.book_no
 WHERE r.iss_date BETWEEN '2019-08-06 00:00:00' AND '2019-08-06 23:59:59';

Answer 2

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.

Answer 3

You can use DATE function

AND DATE(iss_date) = '2019-08-06';
