Comparing date values of CURDATE() with a full timestamp field

Question

I have a function that is placing timestamp values (YYYY-MM-DD HH:MM:SS) into META_VALUE column of table META.

What I want to do is to compare

Answer 1

SELECT * FROM table WHERE  BETWEEN 'YYYY-MM-DD 00:00:00' AND 'YYYY-MM-DD 23:59:59'

Allways avoid doing calculations on the field if possible: e.g.

SELECT * FROM table WHERE DATE() = 'YYYY-MM-DD'

will calculate DATE() for ALL rows in that table, so you are really talking wasted cycles here
