You probably want
where cast(transaction_date as date) BETWEEN '2013-04-16' AND
That works on my test case
You could also change the where clause to be >= date and < date+1

Subject: Bug in BETWEEN same DATETIME
I just noticed what I consider to be a bug; and related, has this been
in later versions of MySQL?
We are using:
mysql Ver 14.12 Distrib 5.0.92, for portbld-freebsd8.1 (amd64) using
If you use BETWEEN and the same date for both parts (i.e. you want a
day) it appears that the operator isn't smart enough to consider the
day in the cases where the column is a DATETIME
WHERE `transaction_date` BETWEEN '2013-04-16' AND '2013-04-16'
I actually have to format it like this to get results
WHERE `transaction_date` BETWEEN '2013-04-16 00:00:00' AND '2013-04-16
As it appears that in the first instance it defaults the time to
always, as verified by this:
WHERE `transaction_date` BETWEEN '2013-04-16' AND '2013-04-16 11:59:59'
So, I think it's probably safe to assume that if someone is using the
BETWEEN on datetime columns, their intent more often than not is to get
full 24 hour period, not the 0 seconds it currently pulls by default.
I also tried these hacks as per the web page above, but this doesn't
WHERE `transaction_date` BETWEEN CAST('2013-04-16' AS DATE) AND
CAST('2013-04-16' AS DATE)
WHERE `transaction_date` BETWEEN CAST('2013-04-16' AS DATETIME) AND
CAST('2013-04-16' AS DATETIME)
This one works, but I fail to see how it's any more beneficial than
string without the CAST() overhead?
WHERE `transaction_date` BETWEEN CAST('2013-04-16 00:00:00' AS DATETIME)
CAST('2013-04-16 11:59:59' AS DATETIME)
Or is there some other magical incantation that is supposed to be used
(without me manually appending the time portion)?
