SQL Server 2008加入两个查询

Question

我在这里忽略了一些微不足道的事情.除了尝试连接两个查询之外,此查询不是出于任何原因.我得到的错误是

Msg 156, Level 15, State 1, Line 10
Incorrect syntax near the keyword 'inner'.
Msg 156, Level 15, State 1, Line 16
Incorrect syntax near the keyword 'as'.

而查询是

select t.countyName, x.countyName
    from
    (

    SELECT DISTINCT Patient.patientid, tblStateCounties.countyName, Patient.countyCode
    FROM         Patient INNER JOIN
                          tblStateCounties ON Patient.stateCode = tblStateCounties.stateCode AND Patient.countyCode = tblStateCounties.countyCode
    WHERE     (Patient.patientage > 80)
    ) 
    inner join 
    (
    SELECT DISTINCT Patient.patientid, tblStateCounties.countyName, Patient.countyCode
    FROM         Patient INNER JOIN
                          tblStateCounties ON Patient.stateCode = tblStateCounties.stateCode AND Patient.countyCode = tblStateCounties.countyCode
    WHERE     (Patient.patientage < 80)
    ) as x on t.countyname=x.countyname

Answer 1

你忘了在第一个中使用别名subquery.
