SQL：使用'；而且不存在'；语法问题

我试图创建一个查询，向我显示在日期范围1中使用其帐户中的服务，然后在日期范围2中未使用其帐户中的服务的成员

我使用“AND NOT EXISTS”创建了一个嵌套查询，但我一直收到一个错误，我不知道原因

SELECT        
    SS.memid
FROM
    SS 
INNER JOIN
    SSUSED ON SS.ssid = SSUSED.ssid 
INNER JOIN
    MEMBERS ON SS.memid = MEMBERS.memid 
INNER JOIN
    PRODUCTS ON SS.productid = PRODUCTS.productid 
INNER JOIN
    PRODUCTCATS ON PRODUCTS.productcatid = PRODUCTCATS.productcatid 
                AND NOT EXISTS (SELECT SS_1.memid
                                FROM SS AS SS_1  
                                INNER JOIN SSUSED AS SSUSED_1 ON SS_1.ssid = SSUSED_1.ssid 
                                INNER JOIN MEMBERS AS MEMBERS_1 ON SS_1.memid = MEMBERS_1.memid 
                                INNER JOIN PRODUCTS AS PRODUCTS_1 ON SS_1.productid = PRODUCTS_1.productid 
                                INNER JOIN PRODUCTCATS AS PRODUCTCATS_1 ON PRODUCTS_1.productcatid = PRODUCTCATS_1.productcatid
                                WHERE (SSUSED_1.usedate BETWEEN @rvStartWeek2 AND @rvEndWeek2) 
                                  AND (PRODUCTS_1.productcatid IN (27, 28, 29, 58, 77, 75, 30, 61, 31, 32, 47, 68)) 
                                  AND (MEMBERS_1.siteid = @rvSite)
                           )
WHERE        
    (SSUSED.usedate BETWEEN @rvStartWeek1 AND @rvEndWeek1) 
    AND (PRODUCTS.productcatid IN (27, 28, 29, 58, 77, 75, 30, 61, 31, 32, 47, 68)) 
    AND (MEMBERS.siteid = @rvSite)

我得到的错误如下：

也许，问题在于主查询没有链接到不存在的子查询。 试试看：

为所有表（而不仅仅是子查询）创建别名 在子查询的“where”上加入主查询

    SELECT        
    SS_0.memid
FROM
    SS SS_0
INNER JOIN
    SSUSED SSUSED_0 ON SS_0.ssid = SSUSED_0.ssid 
INNER JOIN
    MEMBERS MEMBERS_0 ON SS_0.memid = MEMBERS_0.memid 
INNER JOIN
    PRODUCTS PRODUCTS_0 ON SS_0.productid = PRODUCTS_0.productid 
INNER JOIN
    PRODUCTCATS PRODUCTCATS_0 ON PRODUCTS.productcatid = PRODUCTCATS.productcatid 
                AND NOT EXISTS (SELECT SS_1.memid
                                FROM SS AS SS_1  
                                INNER JOIN SSUSED AS SSUSED_1 ON SS_1.ssid = SSUSED_1.ssid 
                                INNER JOIN MEMBERS AS MEMBERS_1 ON SS_1.memid = MEMBERS_1.memid 
                                INNER JOIN PRODUCTS AS PRODUCTS_1 ON SS_1.productid = PRODUCTS_1.productid 
                                INNER JOIN PRODUCTCATS AS PRODUCTCATS_1 ON PRODUCTS_1.productcatid = PRODUCTCATS_1.productcatid
                                WHERE (SSUSED_1.usedate BETWEEN @rvStartWeek2 AND @rvEndWeek2) 
                                  AND (PRODUCTS_1.productcatid IN (27, 28, 29, 58, 77, 75, 30, 61, 31, 32, 47, 68)) 
                                  AND (MEMBERS_1.siteid = @rvSite)
                                  AND (SS_0.memid = SS_1.memid) -- Joint main Query and Subquery
                           )
WHERE        
    (SSUSED_0.usedate BETWEEN @rvStartWeek1 AND @rvEndWeek1) 
    AND (PRODUCTS_0.productcatid IN (27, 28, 29, 58, 77, 75, 30, 61, 31, 32, 47, 68)) 
    AND (MEMBERS_0.siteid = @rvSite)

错误消息表示您无权访问用作参数的CLR类型。我不确定这和你的问题有什么关系。
