使用单个表insqlserver中的leftouterjoin. [英] using leftouterjoin from single table insqlserver.

问题描述

所有我有一个要求，我需要从单个表中获取值，该表具有3个列id，name，id = 1的值，我有4个名称(a，b，c，d)并具有值因为它像a一样有10个值，b和c和d都有10个值，并且id = 2我只有3个名字(a，b，c)每个都有10个值，现在我的要求是得到这样产生的结果

HI all i had a requirement where i need to get a values from single table , the table has 3 colms id,name,value for id=1 i have 4 names (a,b,c,d) and has values for it like for a there are 10 values for b 10 values same for c and d, and for id=2 i have only 3 names (a,b,c) with 10 values for each , now my requirement here is to get the result in this way

name  id       values(sum(values))        id          values<br />
<br />
a       1             15                   2            187<br />
b       1              20                  2            168<br />
c       1             18                   2            132<br />
d       1             31                   Null         Null

我尝试了左外部联接和内联查询，但是我失败了，是否由于相同的表值和组而失败了?我不确定是否有任何方法可以实现它，请指导我谢谢
