Question

提前感谢您的帮助！

我需要根据2个不同的SELECT

加入2个表

首先选择：

SELECT
Agent, 
count( Online_playerdatabase_v2.First_Deposit_Date) as NumbFirstDeposits
FROM Online_playerdatabase_v2
WHERE Agent <>'Agent' AND Online_playerdatabase_v2.First_Deposit_Date BETWEEN '2015-12-01' AND '2015-12-31'
group by Agent



Output:
Agent       NumbFirstDeposits
john            49
No Agent        1
mike            9

然后另一个选择：

SELECT  
   Agent,
    COUNT(DISTINCT Online_customer_activity_v2.Customers) as ActivePlayers, 
    Truncate(sum(Online_customer_activity_v2.Real_Money),0) as RM, 
    Truncate(sum(Online_customer_activity_v2._Bonuses),0) as BO, 
    Truncate(sum(Online_customer_activity_v2.Total_Win_Loss),0) as GGR,
    Truncate(sum(`Online_customer_activity_v2`.`Total_Bets`),0) as BETS
FROM Online_customer_activity_v2
WHERE `Online_customer_activity_v2`.`Date` BETWEEN '2015-12-01' AND '2015-12-31'
AND Online_customer_activity_v2.Total_Bets>0
GROUP BY Agent

Output:
Agent       ActivePlayers   RM      BO      GGR BETS
john        73              63118   28538   64  1395799
No Agent    1               80      0   -   21      876
mike        24              209780  28464   20  7955633

我希望如下所示加入2个输出：

Agent ActivePlayers RM      BO      GGR     BETS    NumbFirstDeposits
john            73  63118   28538   64      1395799 49
No Agent        1   80      0   -   21      876     1
mike            24  209780  28464   20      7955633 9

Answer 1

在不必重写查询的情况下执行此操作的一种方法是在派生表中使用它们，如下所示：

select t1.*, t2.NumbFirstDeposits
from (<<your first query here>>) t1
join (<<your second query here>> t2 on t1.agent = t2.agent

Answer 2

尝试以这种方式应用联接：

SELECT ***your_column_names_here***
FROM Online_playerdatabase_v2 as  P
join Online_customer_activity_v2 as C on P.Agent=C.agent
WHERE
***conditions***
Group BY p.Agent

Answer 3

你可以试试这个，

SELECT Online_customer_activity_v2.Agent,
COUNT(DISTINCT Online_customer_activity_v2.Customers) as ActivePlayers, 
Truncate(sum(Online_customer_activity_v2.Real_Money),0) as RM, 
Truncate(sum(Online_customer_activity_v2._Bonuses),0) as BO, 
Truncate(sum(Online_customer_activity_v2.Total_Win_Loss),0) as GGR,
Truncate(sum(`Online_customer_activity_v2`.`Total_Bets`),0) as BETS,
count( Online_playerdatabase_v2.First_Deposit_Date) as NumbFirstDeposits FROM Online_customer_activity_v2 join Online_playerdatabase_v2 on Online_playerdatabase_v2.agent=Online_customer_activity_v2.agent WHERE `Online_customer_activity_v2`.`Date` BETWEEN '2015-12-01' AND '2015-12-31' AND Online_customer_activity_v2.Total_Bets>0 GROUP BY Online_customer_activity_v2.Agent
