Question

我正在尝试使用以下内容在MSSQL 2012中编译子查询以提取导入货件中的容器卷

SELECT TOP (100) PERCENT JobShipment_1.JS_UniqueConsignRef, JobContainer_1.JC_ContainerNum,
                      (SELECT dbo.JobPackLines.JL_ActualVolume
                       FROM      dbo.JobPackLines INNER JOIN
                                         dbo.JobShipment ON dbo.JobPackLines.JL_JS = dbo.JobShipment.JS_PK INNER JOIN
                                         dbo.JobContainerPackPivot ON dbo.JobPackLines.JL_PK = dbo.JobContainerPackPivot.J6_JL INNER JOIN
                                         dbo.JobContainer ON dbo.JobContainerPackPivot.J6_JC = dbo.JobContainer.JC_PK) AS Expr1
FROM     dbo.JobConsol INNER JOIN
                  dbo.JobConShipLink ON dbo.JobConsol.JK_PK = dbo.JobConShipLink.JN_JK INNER JOIN
                  dbo.JobShipment AS JobShipment_1 ON dbo.JobConShipLink.JN_JS = JobShipment_1.JS_PK INNER JOIN
                  dbo.cvw_JobShipmentOrgs ON JobShipment_1.JS_PK = dbo.cvw_JobShipmentOrgs.JS_PK INNER JOIN
                  dbo.JobContainer AS JobContainer_1 ON dbo.JobConsol.JK_PK = JobContainer_1.JC_JK INNER JOIN
                  dbo.JobDeclaration ON JobShipment_1.JS_PK = dbo.JobDeclaration.JE_JS

但是得到以下错误

“错误消息：子查询返回的值超过1。当子查询跟随=，！=，＆lt;，＆lt; =，＆gt;，＆gt; =或子查询用作表达式时，不允许这样做。 “

我在网上看起来很恶心，但无法找到答案，有人可以帮忙吗？非常感谢

请尝试以下：

    SELECT TOP (100) PERCENT JobShipment_1.JS_UniqueConsignRef, JobContainer_1.JC_ContainerNum,
        (SELECT JPL.JL_ActualVolume
        FROM dbo.JobPackLines AS JPL
        INNER JOIN dbo.JobShipment AS JS ON JS.JS_PK = JPL.JL_JS
        INNER JOIN dbo.JobContainerPackPivot AS JCP ON JCP.J6_JL = JPL.JL_PK 
        INNER JOIN dbo.JobContainer AS JC ON JC.JC_PK = JPL.J6_JC) AS Expr1
    FROM  dbo.JobConsol 
    INNER JOIN dbo.JobConShipLink ON dbo.JobConsol.JK_PK = dbo.JobConShipLink.JN_JK 
    INNER JOIN dbo.JobShipment AS JobShipment_1 ON dbo.JobConShipLink.JN_JS = JobShipment_1.JS_PK 
    INNER JOIN dbo.cvw_JobShipmentOrgs ON JobShipment_1.JS_PK = dbo.cvw_JobShipmentOrgs.JS_PK 
    INNER JOIN dbo.JobContainer AS JobContainer_1 ON dbo.JobConsol.JK_PK = JobContainer_1.JC_JK 
    INNER JOIN dbo.JobDeclaration ON JobShipment_1.JS_PK = dbo.JobDeclaration.JE_JS
