Mysql的數量和總排

Question

我有一個MySQL查詢（由史記創建）： -

SELECT  'blr' AS Location,  COUNT(*) AS playCnt,  (select count(*) from blr_skip WHERE blr_skip_dt like '%2016-03-20%') as skipCnt FROM blr_play WHERE blr_play_dt like '%2016-03-20%' UNION SELECT  'chen' AS Location,  COUNT(*) AS playCnt,  (select count(*) from chen_skip WHERE chen_skip_dt like '%2016-03-20%') as skipCnt FROM chen_play WHERE chen_play_dt like '%2016-03-20%'; 

這使輸出這樣的： -

+----------+---------+---------+ 
| Location | playCnt | skipCnt | 
+----------+---------+---------+ 
| blr  |  25 |  8 | 
| chen  |  12 |  1 | 
+----------+---------+---------+ 

我想補充的多一個排在這樣的專欄結尾總： -

+----------+---------+---------+ 
| Location | playCnt | skipCnt | 
+----------+---------+---------+ 
| blr  |  25 |  8 | 
| chen  |  12 |  1 | 
+----------+---------+---------+ 
|Total  |  37 |  9 | 
+----------+---------+---------+ 

Answer 1

試試這個：

SELECT 
    IFNULL(Location, 'Total') AS Location, 
    SUM(playCnt) AS playCnt, 
    SUM(skipCnt) AS playCnt 
FROM 
(
    SELECT  'blr' AS Location,  COUNT(*) AS playCnt,  (select count(*) from blr_skip WHERE blr_skip_dt like '%2016-03-20%') as skipCnt 
    FROM blr_play 
    WHERE blr_play_dt like '%2016-03-20%' 
    UNION 
    SELECT  'chen' AS Location,  COUNT(*) AS playCnt,  (select count(*) from chen_skip WHERE chen_skip_dt like '%2016-03-20%') as skipCnt 
    FROM chen_play 
    WHERE chen_play_dt like '%2016-03-20%' 
) t1 
GROUP BY Location WITH ROLLUP;
