第二次约会要在第一次约会之前。您是在2010年9月29日至2010年1月30日之间查询的)。试着颠倒一下日期的顺序:

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

仅仅将date_field转换为date

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

第二次约会要在第一次约会之前。您是在2010年9月29日至2010年1月30日之间查询的)。试着颠倒一下日期的顺序:

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

使用Date和Time值时，必须将字段转换为DateTime而不是Date。 试一试:

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))

我刚刚在mariaDB上测试了2个案例，如下:

Case 1: SELECT * FROM table_name WHERE DATE(date_field) BETWEEN '2016-12-01' AND '2016-12-10' // include 2016-12-10
Case 2: SELECT * FROM table_name WHERE (date_field BETWEEN '2016-12-01' AND '2016-12-10') // not include 2016-12-10

您的查询应该有日期为

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')
