Question

我正在尝试根据当天创建一个拉取的查询。我不知道WHERE中的参数，目前，我将日期用作字符串。

SELECT`u.firstname AS `user`,COUNT(acc.submit_dt) AS `submitted`
FROM asset_camera_check AS acc JOIN users u ON u.userid = acc.user_id 
WHERE(acc.submit_dt = currentdate AND 
      acc.submit_dt < '2016-3-23 6:00:00'GROUP BY u.userid

Answer 1

你的WHERE子句需要一个右括号（或者只是去掉左括号 - 你不需要括号）。

除了语法之外，如果您尝试做的是在00:00（包括）和06:00（不包括）之间包含＆＃34;今天＆＃34;的记录，请尝试以下内容：

SELECT
  u.firstname AS `user`,
  COUNT(acc.submit_dt) AS `submitted`
FROM asset_camera_check AS acc
JOIN users u ON u.userid = acc.user_id
WHERE acc.submit_dt >= current_date
  AND acc.submit_dt < current_date + interval 6 hour
GROUP BY u.userid
