...             ....                 ...       ...         ...我想把同一卡号的金额统计统计到一起，应该怎么做？
如卡号为7689600000000000148 金额为 0.01+0.01+0.01+0.01+0.01=0.05
卡号非常多。

Answer 1

select t.卡号,sum(t.金额)
from table_t t
group by t.卡号

Answer 2

--???
select 卡号,sum(支付金额) 支付金额 from t group by 卡号;

Answer 3

如只是某一类卡号：
select sum(支付金额) from tabnam where 卡号 = '7689600000000000148'

Answer 4

select 卡号,
        sum(支付金额) 支付金额 
from tb1 
group by 卡号;
执行下来是什么错误 计算错误还是？   如果不能满足要求 只能说明 lZ的要求说的不明确了
