如何使用MySQL和計數和排名

Question

我是MS-SQL開發人員，現在我使用這個查詢（MySQL）↓

SELECT A.place_idx,A.place_id,B.TODAY_CNT,C.TOTAL_CNT FROM CUSTOM_LIST 

AS A

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TODAY_CNT from COUNT_TABLE where DATE(place_date) = DATE(NOW()) GROUP BY place_id)
AS B ON B.place_id=A.place_id

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TOTAL_CNT from COUNT_TABLE GROUP BY place_id)
AS C ON C.place_id=A.place_id

結果是：

我要這個：

Answer 1

試試這樣的想法：

SELECT ..., C.TOTAL_CNT, (@r := @r + 1) AS rank FROM CUSTOM_LIST, (SELECT  @r := 0) t
...
ORDER BY C.TOTAL_CNT DESC

整個查詢：

SELECT A.place_idx,A.place_id,B.TODAY_CNT,C.TOTAL_CNT, (@r := @r + 1) AS rank 
FROM CUSTOM_LIST AS A, (SELECT  @r := 0) t

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TODAY_CNT from COUNT_TABLE where DATE(place_date) = DATE(NOW()) GROUP BY place_id)
AS B ON B.place_id=A.place_id

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TOTAL_CNT from COUNT_TABLE GROUP BY place_id)
AS C ON C.place_id=A.place_id

ORDER BY C.TOTAL_CNT DESC

如果我們在Total_CNT中得到兩個相同的值怎么辦？

也許是這樣的：

SELECT ..., (@last := C.TOTAL_CNT) AS TOTAL_CNT, 
  IF(@last = C.TOTAL_CNT, @r, @r := @r + 1) AS rank
FROM CUSTOM_LIST, (SELECT  @r := 0, @last := -1) t
...

Answer 2

更新

RANK（）（按TOTAL_CNT DESC DESC排序）作為Rank

在這里，我得到了另一個非常好的解

SELECT A.place_idx,A.place_id,B.TODAY_CNT,C.TOTAL_CNT, RANK() OVER (ORDER BY TOTAL_CNT DESC) AS Rank FROM CUSTOM_LIST 

AS A

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TODAY_CNT from COUNT_TABLE where DATE(place_date) = DATE(NOW()) GROUP BY place_id)
AS B ON B.place_id=A.place_id

INNER JOIN
(SELECT place_id,COUNT(place_id) AS TOTAL_CNT from COUNT_TABLE GROUP BY place_id)
AS C ON C.place_id=A.place_id
