Question

我正在尝试将一些数据插入临时表（#temptable），插入后我想执行Sum（金额），它与相同的ID和组匹配的是cust的名称和账单ID，我想选择这些匹配ID中可用的最早日期。完成所有这些操作后，我想更新原始表（billtable）

Bill ID   Amount  CUstName   Duedate

12         12.2     ABC        12222016
12         22.2     ABC        12112016
13         23.22    ABC        12102016

Bill ID   Amount  CUstName   Duedate

12         34.4     ABC        12112016
13         23.22    ABC        12102016

Answer 1

你需要类似下面的内容

If(OBJECT_ID('tempdb..#t') Is Not Null)
Begin
    Drop Table #t
End

 create table #t
(
billid varchar (50),
amount decimal,
cust varchar (50),
duedate datetime
)

insert into #t (billid,amount,cust,duedate) values ('12',12.2,'abc','20161222')
insert into #t (billid,amount,cust,duedate) values ('12',22.2,'abc','20161211')
insert into #t (billid,amount,cust,duedate) values ('13',23.22,'abc','20161210')
insert into #t (billid,amount,cust,duedate) values ('12',34.4,'abc','20161211')
insert into #t (billid,amount,cust,duedate) values ('13',23.22,'abc','20161210')

select billid,sum(amount),MIN(duedate)
from #t
group by billid

SQL - 来自临时表的{INSERT AND UPDATE表
