How do I query between two dates using MySQL?

The following query:

SELECT * FROM `objects` 
WHERE (date_field BETWEEN '2010-09-29 10:15:55' AND '2010-01-30 14:15:55')

returns nothing.

I should have more than enough data to for the query to work though. What am I doing wrong?

Your second date is before your first date (ie. you are querying between September 29 2010 and January 30 2010). Try reversing the order of the dates:

SELECT *
FROM `objects`
WHERE (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')

Your query should have date as

select * from table between `lowerdate` and `upperdate`

try

SELECT * FROM `objects` 
WHERE  (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')

Is date_field of type datetime? Also you need to put the eariler date first.

It should be:

SELECT * FROM `objects` 
WHERE  (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')

DATE() is a MySQL function that extracts only the date part of a date or date/time expression

SELECT * FROM table_name WHERE DATE(date_field) BETWEEN '2016-12-01' AND '2016-12-10';

As extension to the answer from @sabin and a hint if one wants to compare the date part only (without the time):

If the field to compare is from type datetime and only dates are specified for comparison, then these dates are internally converted to datetime values. This means that the following query

SELECT * FROM `objects` WHERE (date_time_field BETWEEN '2010-01-30' AND '2010-09-29')

will be converted to

SELECT * FROM `objects` WHERE (date_time_field BETWEEN '2010-01-30 00:00:00' AND '2010-09-29 00:00:00')

internally.

This in turn leads to a result that does not include the objects from 2010-09-29 with a time value greater than 00:00:00!

Thus, if all objects with date 2010-09-29 should be included too, the field to compare has to be converted to a date:

SELECT * FROM `objects` WHERE (DATE(date_time_field) BETWEEN '2010-01-30' AND '2010-09-29')

You can do it manually, by comparing with greater than or equal and less than or equal.

 select * from table_name where created_at_column  >=   lower_date  and  created_at_column <= upper_date;

In our example, we need to retrieve data from a particular day to day. We will compare from the beginning of the day to the latest second in another day.

  select * from table_name where created_at_column  >=   '2018-09-01 00:00:00'  and  created_at_column <= '2018-09-05 23:59:59';

Just Cast date_field as date

SELECT * FROM `objects` 
WHERE (cast(date_field as date) BETWEEN '2010-09-29' AND 
'2010-01-30' )

When using Date and Time values, you must cast the fields as DateTime and not Date. Try :

SELECT * FROM `objects` 
WHERE (CAST(date_field AS DATETIME) 
BETWEEN CAST('2010-09-29 10:15:55' AS DATETIME) AND CAST('2010-01-30 14:15:55' AS DATETIME))

Might be a problem with date configuration on server side or on client side. I've found this to be a common problem on multiple databases when the host is configured in spanish, french or whatever... that could affect the format dd/mm/yyyy or mm/dd/yyyy.

Try switching the dates around:

2010-09-29 > 2010-01-30?

To display post(s) between 2 specific dates (for example):

an occasion starts on (04-12) and ends on (04-14) without selecting a year in query to make it recurrent every year on the specified dates, So my goal is to display that occasion on startdate and hide it automatically on enddate as follow:

$stmt = $db->query(
    "SELECT * FROM table

    WHERE (CAST(CURDATE() AS date)

    BETWEEN

    CAST(table.date_start AS date)
    AND
    CAST(table.date_end AS date))

    LIMIT 1"
);

Now, the occasion starts and disappear between these specified dates only, not after or before.
