MySQL选择中的组和子组表

Question

我有一个Table SalesInvoice。在此日期中，金额模式是此表中的重要列。

SNo            BID          iDate          Amount         Mode
----------------------------------------------------------------
101             1         2016-01-01        200          Cash
102             2         2016-01-01        500          Credit
103             5         2016-01-01        800          credit
104             8         2016-01-01        250          Cash
105             1         2016-01-01        200          Cash
106             2         2016-01-02        500          Cash
107             5         2016-01-03        800          Credit
108             8         2016-01-03        250          Credit

我的要求输出是

 iDate       MinSno    MaxSno     Total      CreditTotal    CashTotal
----------------------------------------------------------------------
2016-01-01     101       105       1950           1300          650
2016-01-02     106       106        500              0          500
2016-01-03     107       108       1050           1050            0

我尝试了MySQL查询

SELECT iDate, Min(SNo) AS MinSno, Max(SNo) AS MaxSno, SUM(Amount) 
From SalesInvoice GROUP By iDate

但是，我不知道如何根据主要集团iDate中的子集团获得现金和信贷金额。请帮助我，如何达到上述预期的产量？

Answer 1

这似乎有效：

SELECT iDate, min(SNo) as MinSno, max(SNo) as MaxSno, sum(amount) as Total,
sum(If(MMode = 'Cash',Amount,0)) as Cash,
sum(If(MMode = 'Credit',Amount,0)) as Credit
from test.SalesInvoice
Group By iDate;

请注意，我将Mode更改为MMode，因为Mode是MySQL中的关键工具
