Question

美好的一天！我一直在圈子里寻找解决这个问题的方法，我总结了我的专栏

SELECT sum(sp1)
     , sum(sp2)
     , sum(sp3)
     , sum(sp4)
     , sum(fsg)
     , sum(fgg)
     , sum(ffg)
     , sum(fsf)
     , sum(fgf)
     , sum(fff)
     , sum(g1)
     , sum(g2)
     , sum(g3)
     , sum(gb35)
     , sum(gb452mm)
     , sum(gb453mm)
     , sum(gb454mm)
     , (sum(sp1) + sum(sp2) + sum(sp3) + sum(sp4) + sum(fsg) + sum(fgg) + sum(ffg) + sum(fsg) + sum(fgf) 
      + sum(fff) + sum(g1) + sum(g2) + sum(g3) + sum(gb35) + sum(gb452mm) + sum(gb453mm) + sum(gb454mm)) total
     , monthx
     , yearx
     , monthval 
  FROM tbl_incoming 
 WHERE yearx = '" & AnnualSelectYearFrm.ComboBox3.Text & "' 
 GROUP 
    BY monthx
     , yearx
     , monthval 
 ORDER 
    BY monthval

其中colums的总数（所有列的总和）计算错误，我认为其中一些不在计算中，我一直在想为什么以及导致这种情况的原因。请帮忙。

试试这个：

(spa1+spa2+spa3+spa4)

否则也试试这个：

sum(spa1+spa2)

而不是：

(sum(sp1) + sum(sp2) + sum(sp3) + sum(sp4) + sum(fsg) + sum(fgg) + sum(ffg) + sum(fsg) + sum(fgf) 
  + sum(fff) + sum(g1) + sum(g2) + sum(g3) + sum(gb35) + sum(gb452mm) + sum(gb453mm) + sum(gb454mm)) total

sql中的SUM函数返回错误计算的值
