MySQL DATE_ADD 使用情况，5 天间隔

Question

我试图在单个查询中选择 5 天内的订单总金额 ($) 和发票计数。但我似乎无法让这件事发生。我当前的查询在这里...

SELECT
    COUNT(id) as invoice_count,
    SUM(orderTotal) as orders_sum,
    UNIX_TIMESTAMP(created) as created
FROM ids_invoice
WHERE DATE_ADD(created, INTERVAL +1 DAY)
AND userId = 23 LIMIT 5'

我不完全确定 DATE_ADD 是我正在寻找的正确函数。

目前我正在......

Array ( 
    [0] => Array ( 
        [invoice_count] => 420
        [orders_total] => 97902.90
        [created] => 1252596560
    )
)

Array ( 
    [0] => Array ( 
        [invoice_count] => 68
        [orders_total] => 14193.20
        [created] => 1262900809
    )
)

我想要得到更像......

Array ( 
    [0] => Array ( 
        [invoice_count] => 18
        [orders_total] => 4902.90
        [date] => 04-19-2010
    )
)

Array ( 
    [0] => Array ( 
        [invoice_count] => 12
        [orders_total] => 5193.20
        [date] => 04-20-2010
    )
)

我对 mysql 日期函数相当陌生，所以也许我只是错过了在浏览 mysql 文档时所需的函数。

更新 我已经更新了我的查询...这仍然不会为有发票的每一天提取一行。仅当 20 日有满足 userId 标准的发票时，才会提取 19 日的发票。

SELECT
    COUNT(id) as invoice_count,
    SUM(orderTotal) as orders_sum,
    UNIX_TIMESTAMP(created) as created
FROM ids_invoice
WHERE
    created BETWEEN "2010-04-19 00:00:00" AND DATE_ADD("2010-04-19 00:00:00", INTERVAL +5 DAY) AND
    userId = 17

Answer 1

WHERE created <= NOW() AND created >=NOW() - INTERVAL 5 DAY

或者最好只比较日期时间的 DATE 部分：

WHERE DATE(created) <= date(NOW()) AND 
  DATE(created) >= DATE(NOW() - INTERVAL 5 DAY)

Answer 2

如果您创建的列类型是 int 那么就尝试这个

created<= UNIX_TIMESTAMP(DATE_ADD(CURDATE(),INTERVAL 5 DAY))')

Answer 3

要获取某个日期范围内的记录，请使用：

WHERE created BETWEEN NOW() AND DATE_ADD(NOW(), INTERVAL 5 DAY)

此示例将获取今天和未来几天之间的记录（假设今天存在任何记录，包括时间）。如果您想回到过去，请查看 DATE_SUB。
