如何对查询中的列求和以在文本框中显示结果

Question

我在查询中遇到问题，以获取总和以在我的 vb.net 表单的文本框中显示它

我有两个查询工作正常并显示结果现在我想对两个查询的列求和以在文本框中显示结果。

查询是这样的

Select 
    cl_ccode, co_scode, SUM(im_qty) as invtotal 
from 
    invmast 
where 
    cl_ccode = '3' and co_scode = '271210'
group by 
    cl_ccode, co_scode 

Select 
    cl_ccode, co_scode, SUM(st_qty) as stktotal 
from 
    stock  
where 
    cl_ccode = '3'and co_scode = '271210'
group by 
    cl_ccode, co_scode 

第一个查询的输出是

cl_ccode | co_scode | invtotal
       3 | 271210   | 132200

第二个查询的输出是

cl_ccode | co_scode | stktotal
       3 |   271210 | 386500 

我想在文本框 vb.net 中显示添加 invtotal 和 stktotal 后的结果，即 518700

请指导我如何获得所需的结果？

Answer 1

;with cte as
(
   Select cl_ccode,co_scode, SUM(im_qty)  as invtotal from invmast 
   where cl_ccode='3'and co_scode='271210'
   group by cl_ccode,co_scode 

   union all

   Select cl_ccode,co_scode, SUM(st_qty) as invtotal from stock  
   where cl_ccode='3'and co_scode='271210'
   group by cl_ccode,co_scode 
)

Select sum(invtotal)
from cte
