查找开始日期和结束日期之间的日期

Question

我想检查日期是否在开始日期和结束日期之间。

我添加了一个where子句

where datepaid between '2010-04-01' AND '2010-04-15'

但问题在于它排除了“2010-04-15”。

它应该包括结束日期，我该怎么做？

请帮帮我

问候，

Answer 1

明确指定时间部分：

WHERE datepaid BETWEEN '2010-04-01 00:00:00' AND '2010-04-15 23:59:59'

Answer 2

也许您的日期包括日内时间。 试试这个：

where '2010-04-01' <= datepaid AND datepaid < '2010-04-16'

Answer 3

WHERE   datepaid >= '2010-04-01'
        AND datepaid < '2010-04-15' + INTERVAL 1 DAY

Answer 4

尝试

where datepaid between '2010-04-01' AND '2010-04-15 23:59:59'

Answer 5

这可能是由于日期有时间：

select
    '2010-04-15' between '2010-04-01' AND '2010-04-15', -- 1
    '2010-04-15 12:00:00' between '2010-04-01' AND '2010-04-15', -- 0
    '2010-04-15 12:00:00' between '2010-04-01 00:00:00' AND '2010-04-15 23:59:59' -- 1

在比较之前将时间添加到范围分隔符或截断值：

select
    '2010-04-15 12:00:00' between '2010-04-01 00:00:00' AND '2010-04-15 23:59:59' -- 1
    cast('2010-04-15 12:00:00' as date) between '2010-04-01' AND '2010-04-15' -- 1

我没有检查，但我认为没有铸造，性能会更好。

其中CONVERT（VARCHAR（10），datepaid，23）在'2010-04-01'和'2010-04-15'之间

添加此子句：

OR datepaid = '2010-04-15'
