目前,我正在使用MySQL 5.6.30,我需要您的幫助。創建從最小量到最大量組的排序按多列
下面是其中的名字是temp_work
+----+-----------+----------+----------+--------+---------+-------+---------+
| id | client_id | account | category | t_year | t_month | t_day | amount |
+----+-----------+----------+----------+--------+---------+-------+---------+
| 1 | 100 | Saving | deposit | 2016 | 12 | 14 | 100.84 |
| 2 | 100 | Checking | withdraw | 2016 | 12 | 15 | 300.24 |
| 3 | 100 | Checking | deposit | 2016 | 12 | 29 | 60.00 |
| 4 | 101 | Saving | Withdraw | 2016 | 12 | 29 | 245.16 |
| 5 | 100 | Saving | Withdraw | 2016 | 12 | 30 | 2200.00 |
| 6 | 100 | Checking | Withdraw | 2016 | 12 | 30 | 2372.16 |
| 7 | 100 | Saving | deposit | 2016 | 12 | 30 | 4327.00 |
| 8 | 101 | Checking | Withdraw | 2017 | 1 | 3 | 80.00 |
| 9 | 101 | Checking | Withdraw | 2017 | 1 | 3 | 1033.45 |
| 10 | 100 | Saving | Withdraw | 2017 | 1 | 3 | 1339.16 |
| 11 | 100 | Checking | deposit | 2017 | 1 | 4 | 140.00 |
| 12 | 100 | Checking | Withdraw | 2017 | 1 | 4 | 216.73 |
| 13 | 101 | Checking | Withdraw | 2017 | 1 | 4 | 1261.72 |
+----+-----------+----------+----------+--------+---------+-------+---------+
表中的數據,我需要從最低量最大量組的秩的CLIENT_ID,帳戶,類別,t_year,t_month。
所以,這是我所期待的或類似的
+-----------+----------+----------+--------+---------+---------+------+
| client_id | account | category | t_year | t_month | amount | rank |
+-----------+----------+----------+--------+---------+---------+------+
| 100 | Checking | deposit | 2016 | 12 | 60.00 | 1 |
| 100 | Checking | deposit | 2017 | 1 | 140.00 | 1 |
| 100 | Checking | withdraw | 2016 | 12 | 300.24 | 1 |
| 100 | Checking | withdraw | 2016 | 12 | 2327.16 | 2 |
| 100 | Checking | Withdraw | 2017 | 1 | 216.73 | 1 |
| 100 | Saving | deposit | 2016 | 12 | 100.84 | 1 |
| 100 | Saving | deposit | 2016 | 12 | 4327.00 | 2 |
| 100 | Saving | Withdraw | 2016 | 12 | 2200.00 | 1 |
| 100 | Saving | Withdraw | 2017 | 1 | 1339.16 | 1 |
| 101 | Checking | Withdraw | 2017 | 1 | 80.00 | 1 |
| 101 | Checking | Withdraw | 2017 | 1 | 1033.45 | 2 |
| 101 | Checking | Withdraw | 2017 | 1 | 1261.72 | 3 |
| 101 | Saving | Withdraw | 2016 | 12 | 245.16 | 1 |
+-----------+----------+----------+--------+---------+---------+------+
這是我第一次嘗試:
Select
tw1.client_id, tw1.account, tw1.category, tw1.t_year, tw1.t_month, tw1.amount
,@rownum = case when @tmonth <> tw1.t_month then 0 else @rownum + 1 end as ranking
,@tmonth := t_month as cmonth
From
(Select @rownum := 0 from dual) as r,
(Select @tmonth := 0 from dual) as m,
(Select client_id, account, category, t_year, t_month, amount
From temp_work as tw
Order by client_id, account, category, t_year, t_month, amount) as tw1
第二個嘗試:
Select tw1.client_id, tw1.account, tw1.category, tw1.t_year, tw1.t_month, tw1.amount
,@rownum = case when concat(@tyear, '-', @tmonth) <> concat(t_year, '-', t_month) then 0 else @rownum + 1 end as rank
,@tyear := t_year as cyear
,@tmonth := t_month as cmonth
From
(Select @rownum := 0) as r,
(Select @tyear := 0) as y,
(Select @tmonth := 0) as m,
(
Select client_id, account, category, t_year, t_month, amount
From temp_work
Order by tw.client_id, tw.account, tw.category, t_year, t_month, tw.amount
) as tw1
然而,上述查詢給我的相同的結果如下。
+-----------+----------+----------+--------+---------+---------+------+
| client_id | account | category | t_year | t_month | amount | rank |
+-----------+----------+----------+--------+---------+---------+------+
| 100 | Checking | deposit | 2016 | 12 | 60.00 | 1 |
| 100 | Checking | deposit | 2017 | 1 | 140.00 | 1 |
| 100 | Checking | withdraw | 2016 | 12 | 300.24 | 1 |
| 100 | Checking | withdraw | 2016 | 12 | 2327.16 | 0 |
| 100 | Checking | Withdraw | 2017 | 1 | 216.73 | 1 |

| 100 | Saving | deposit | 2016 | 12 | 4327.00 | 0 |

| 101 | Checking | Withdraw | 2017 | 1 | 80.00 | 1 |
| 101 | Checking | Withdraw | 2017 | 1 | 1033.45 | 0 |
| 101 | Checking | Withdraw | 2017 | 1 | 1261.72 | 0 |
| 101 | Saving | Withdraw | 2016 | 12 | 245.16 | 1 |

請給我提示,以解決這個問題。
非常感謝。
這是一個非常困難的模式進行工作。如果你的金額都是+/-,取決於他們的行爲,存款是+和撤回是 - 通常更好。有很多方法來組織這個,但[總帳](https://en.wikipedia.org/wiki/General_ledger)是一個很好的開始。對於事務使用本地'DATE'類型也是一個好主意。獨立的月/年專欄非常令人討厭。 – tadman
