試圖按日期分組的日期時間類型，而不是時間與MySQL

Question

我有一張桌子，如下所示：

  block int not null
  day datetime not null
  user int

我想要

  select day, count(*) 
  from TABLE 
  where date between date() and TARDATE 
  group by day 
  order by day desc

問題是，我只想按日期而不是時間分組。

我將如何在MySQL / php中做到這一點？

Answer 1

嘗試

SELECT DATE(`day`) as `DAY`, COUNT(*) totalCount
FROM   TABLE 
WHERE  date BETWEEN date() AND TARDATE 
GROUP BY DATE(`day`)
ORDER BY day DESC

Answer 2

試試這個

SELECT DATE(day), COUNT(*) as total_no FROM TABLE WHERE  date ( BETWEEN date() AND TARDATE ) GROUP BY DATE(day) ORDER BY day DESC
