Question

我有查询我需要比较按借记卡贷记分组的金额字段，我想获得信用额度不等于查询借记金额的输出

select t_vocno,
       sum(t_amt),
       dc_type 
from   accotran 
where  f_yr = '1718' 
and    comp_cd = 'skl' 
group by  t_vocno, 
          dc_type 
order by t_vocno

给出输出

1   215452.1600 D
1   215452.1600 C
2   207586.0000 D
2   207586.0000 C
3   248789.0000 D
3   248789.0000 C

我有非常的出价数据，因此我想提出有条件并获取数据，其中借记＆lt;＆gt;信用

我试过了

select t_vocno,
       sum(t_amt),
       dc_type 
from   accotran 
where  f_yr = '1718' 
and    comp_cd = 'skl' 
group by t_vocno,
         dc_type 
having case when dc_type= 'c' and t_vocno = t_vocno then sum(t_amt) end <>
       case when dc_type= 'd' and t_vocno = t_vocno then sum(t_amt)  end
order by t_vocno

Answer 1

您可以GROUP BY只需t_vocno并使用条件汇总来计算信用卡/借记卡金额：

select t_vocno,
       sum(case when dc_type= 'c' then t_amt else 0 end) as c_sum,
       sum(case when dc_type= 'd' then t_amt else 0 end) as d_sum
from   accotran 
where  f_yr = '1718' 
and    comp_cd = 'skl' 
group by t_vocno
having sum(case when dc_type= 'c' then t_amt else 0 end) <>
       sum(case when dc_type= 'd' then t_amt else 0 end)
order by t_vocno

由于Group子句，Sql Query比较具有不同值的相同字段
