关键字“or”附近的语法不正确。 在滚动范围的标准中

Question

我在一个更大的 select 语句中展示了两个嵌套的 select 语句。 实际上有 10 个汇总了产品的销售/已发行/使用情况，标准是匹配仓库和项目，然后是今年、去年、两年前的日期值范围。 没有 datetime 列，用于确定日期的列是[Year]和[Month]列。 我必须从提到的日期标准中得到总和。

我用于 static 和 YTD 的所有陈述都可以正常工作。 但是，当我使用“或”语法说“从 2 年前的月份 >= 到我当前月份的所有内容”时，效果很好，但是当我添加 or 以包含今年的所有内容以及月份为 <=当前月份”我得到了 OR 错误。此外，由于某种原因，AS 现在导致了可耻的语法错误，但是关键字 AS（关键字“as”附近的语法不正确）别名中的下划线是否会导致：

关键字“as”附近的语法不正确

错误？

您在末尾缺少一个右括号：

(

    SELECT SUM(sold) + sum(Issued)AS Expr1
    FROM dbo.M_NewtrnYM 
    WHERE 
        (WH = dbo.ac_Inventory_WH_Class_MP_Itnbr_Dtl.Warehouse) 
        AND (ITEM = dbo.ac_Inventory_WH_Class_MP_Itnbr_Dtl.ItemNumber) 
        AND (YEAR = year(dateadd(m, -6, getdate() - datepart(d, getdate()) + 1))) 
        and (CAST([Month] as Integer) >=   month(dateadd(m, -6, getdate() - datepart(d, getdate()) + 1)) or (YEAR = YEAR(CURRENT_TIMESTAMP)) and (CAST([Month] as Integer) <=  Month(CURRENT_TIMESTAMP)))
)

此外，您可以删除AND条件上的一些括号并查看您的最后一个条件，您确定这是您想要的吗？

(

    SELECT SUM(sold) + sum(Issued)AS Expr1
    FROM dbo.M_NewtrnYM 
    WHERE 
        WH = dbo.ac_Inventory_WH_Class_MP_Itnbr_Dtl.Warehouse
        AND ITEM = dbo.ac_Inventory_WH_Class_MP_Itnbr_Dtl.ItemNumber
        AND YEAR = year(dateadd(m, -6, getdate() - datepart(d, getdate()) + 1))
        and 
        (
            CAST([Month] as Integer) >=   month(dateadd(m, -6, getdate() - datepart(d, getdate()) + 1)) 
            or 
            YEAR = YEAR(CURRENT_TIMESTAMP) 
            and 
            CAST([Month] as Integer) <=  Month(CURRENT_TIMESTAMP)
        )
)

你有 X 或 Y 和 Z。如果 X 为真，Z 将不会被忽略。
