Question

I have query like below

SELECT * FROM programs where startTime between now() and now() + INTERVAL 1 DAY;

Is it possible to write query with time between now and midnight of today in MySQL?

Something like below

SELECT * FROM programs where startTime between now() and now() + midnight 12;

Answer 1

I suggest you always use clopen (closed-open) intervals for dates and times comparisons. BETWEEN means closed intervals (from both sides). A very good explanation is in @Aaron Bertrand’s blog post: What do BETWEEN and the devil have in common?. Here’s a way to write the query:

SELECT * 
FROM programs 
WHERE startTime >= NOW() 
  AND startTime < CURRENT_DATE() + INTERVAL 1 DAY ;
