Question

比方说，我有如下表：

ID, Name ,insurance , per_diem, net_salary, rr, rent, other_allowances 
1, John  1000   0   2000  0 0   0 
2, Jim  1000   0   2000  0 0   0 
3, Steve 500   0   3000  0 0   0 
4, Tom  0    0   0  0 0   0 

我运行下面的查询

SELECT Sum((((((applicant.insurance + applicant.per_diem) + 
       applicant.net_salary) + applicant.rr) + applicant.rent) + 
       applicant.other_allowances)) As available_fund 
WHERE applicant.id = id; 
From applicant 

我想要得到的东西好像和每个人

是它可能？

Answer 1

您必须先使用，然后使用其中

 SELECT Sum(applicant.insurance + applicant.per_diem + 
       applicant.net_salary + applicant.rr + applicant.rent + 
       applicant.other_allowances) As available_fund 
    From applicant 
    group by applicant.id 

它会给所有员工总和，但如果你想获得一些颗粒员工再放入where条件

WHERE applicant.id = id
