从MYSQL的Now()中选择最近7天 [英] Selecting the last 7 days from Now() in MYSQL

问题描述

谢谢您抽出宝贵的时间来回答我的问题.

Thankyou for taking the time to look at my question.

我有这个MYSQL查询:

I have this MYSQL query:

foreach( $wpdb->get_results(
    "SELECT wp_pixelcart_calendar.datefield AS DATE,
    IFNULL(SUM(wp_pixelcart_daily_sales.quantity),0) AS total_sales
    FROM wp_pixelcart_daily_sales RIGHT JOIN wp_pixelcart_calendar ON (DATE(wp_pixelcart_daily_sales.order_date) = wp_pixelcart_calendar.datefield)
    WHERE (wp_pixelcart_calendar.datefield BETWEEN (SELECT MIN(DATE(order_date)) FROM wp_pixelcart_daily_sales) AND (SELECT MAX(DATE(order_date)) FROM wp_pixelcart_daily_sales))
    GROUP BY DATE"
) as $key => $row) {

echo "<br>". $row->DATE . "',". $row->total_sales . "],";

}

在查询中，我很难显示从现在开始的最近7天，我一直在玩:

I'm having a hard time to display the last seven days from now in the query, ive been playing around with:

BETWEEN (SELECT MIN(DATE(order_date)) FROM wp_pixelcart_daily_sales) AND (SELECT MAX(DATE(order_date)) FROM wp_pixelcart_daily_sales))

对此:

BETWEEN NOW() FROM wp_pixelcart_daily_sales) AND DATE_ADD(NOW(), INTERVAL 7 DAY) FROM wp_pixelcart_daily_sales))

但这似乎不起作用.

任何帮助表示赞赏.

谢谢

推荐答案

如果该方法不起作用，则返回0个结果，请考虑交换日期范围:

if this is not working, returning 0 results, consider swapping the dates' range:

BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()
