Question

这已经解决了，我需要在SQL中连接4个表，不同表中的2列是不同的。到现在为止，我会一直得到重复的行。

我有4个表，我试图加入1个查询。

我需要创建一个类似于以下内容的报告：

Select quoteID,insuredFirstName,insuredLastName,quoteType,status, firstname, lastname, adminInitial, userType
from (SELECT Row_Number() Over(Partition by A.quoteid  order by A.quoteid ) as Row , A.quoteID, A.insuredFirstName, A.insuredLastName, A.quoteType, A.status, B.firstName, B.lastName, left(C.firstName,1) + left(C.lastName,1) as adminInitial, D.userType
    FROM quotes A
    INNER JOIN tbl_agents B
    ON A.createUserID = B.AgentNumber
    INNER JOIN tbl_admins C
    ON A.assignedID = C.ID
    INNER JOIN
        (SELECT 
            quoteID, userType
            FROM quote_notes) D
            ON A.quoteID = D.quoteID) as t where row=1

Answer 1

尝试将 DISTINCT 从inner查询移至outside查询。

Answer 2

请尝试使用Row_Number()这样使用Partition by ......

  Select quoteID,insuredFirstName,insuredLastName,quoteType,status from (SELECT Row_Number() Over(Partition by quoteid ,Name1  order by quoteid ) as Row , A.quoteID, A.insuredFirstName, A.insuredLastName, A.quoteType, A.status, B.firstName, B.lastName, left(C.firstName,1) + left(C.lastName,1) as adminInitial, D.userType
        FROM quotes A
        INNER JOIN tbl_agents B
        ON A.createUserID = B.AgentNumber
        INNER JOIN tbl_admins C
        ON A.assignedID = C.ID
        INNER JOIN
            (SELECT 
                quoteID, userType
                FROM quote_notes) D
                ON A.quoteID = D.quoteID) as t where row=1

不同表中的SQL 2列不同
