回复讨论(解决方案)

select 借款,sum(金额) from table group by 借款

好吧，你还是高估了我，

表名：nah
name                   shuliang        danjia         zongjia
a                    100                      0.1               10
b                    200                      0.2               40
a                    50                        0.4                20
b                    30                        0.2               6
c                     100                    0.8                80

按照name分类汇总
得出a   shuliang     150       zongjia       3o
        b  shuliang       230     zongjia       46
        c  shuliang       100    zongjia   80

求以上源代码，小白求码

有什么区别吗？
select name, sum(shuliang) as shuliang, sum(zongjia) as  zongjia from nah group by name
