语法错误:')'
附近的语法不正确
代码:
select
sum(rate)
from
(select
sum(UnitsDelivered * Rate) as rate
from
Reimbursement_EBSUtilization
where
PRR_Id = 1
UNION ALL
select
sum(Reimbursement_CDSUtilization.Rate * CDSUtilization.UnitsDelivered) as rate
from
Reimbursement_CDSUtilization
left join
CDSUtilization on Reimbursement_CDSUtilization.CDSU_Id = CDSUtilization.Id
where
Reimbursement_CDSUtilization.PRR_Id = 270
)--syntax error is showing here
我确信我错过了一些非常小但却无法弄清楚的东西
答案 0 :(得分:2)
您需要为子查询添加别名:
select sum(rate) from
(
select sum(UnitsDelivered*Rate) as rate
from Reimbursement_EBSUtilization
where PRR_Id =1
UNION ALL
select sum(Reimbursement_CDSUtilization.Rate * CDSUtilization.UnitsDelivered) as rate
from Reimbursement_CDSUtilization
left join CDSUtilization on Reimbursement_CDSUtilization.CDSU_Id = CDSUtilization.Id
where Reimbursement_CDSUtilization.PRR_Id = 270
) as t -- <-- use alias here
