Question

What is the largest date PHP and MySQL recognizes?

I mean, I have different values for different timeline and I want to make them all as BETWEEN selects in MySQL, like this:

SELECT * FROM table WHERE date BETWEEN '2011-10-01' AND '2011-10-02';
SELECT * FROM table WHERE date BETWEEN '2011-10-03' AND '2011-10-10';

etc.

To get all options, was thinking of something like this:

SELECT * FROM table WHERE date BETWEEN '0000-01-01' AND '2011-10-01';
SELECT * FROM table WHERE date BETWEEN '2011-10-02' AND '2011-10-10';
SELECT * FROM table WHERE date BETWEEN '2011-10-11' AND '9999-12-31';

Will this always work or is there a chance the code might break at some point?

Answer 1

The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in ‘YYYY-MM-DD’ format. The supported range is ‘1000-01-01’ to ‘9999-12-31’.
