我有一个查询，它根据一组条件收集信息。基本上我想知道一个位置是否在当天支付了超过 50 美元，或者评论部分是否包含“过滤器”这个词......

我的查询是：

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Amount > 50) OR
                         (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')

问题是它返回 460 个结果，应该只返回 2。

您需要将您的 Paid_Out_Amoutn 和 Paid_Out_Comment 标准包装在第二组括号中：

SELECT Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, 
    Update_UserName, Till_Number 
FROM Paid_Out_Tb 
WHERE (Store_Id = 1929) AND (Paid_Out_Datetime >= 
    DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND 
    (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)) AND 
    (
        (Paid_Out_Amount > 50) OR (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')
    )

这实际上取决于您使用 OR 的目的。您有 Paid_Out_Amount 大于 50 或 Paid_Out_Amount 类似于 N%Filter%。在你的子句中添加一些括号

WHERE 
(
    (1 = 1)
    AND
    (2 = 2)
)
OR
( 3 = 3 )

看起来您缺少一组括号：

SELECT        
    Store_Id
    , Paid_Out_Amount
    , Paid_Out_Comment
    , Paid_Out_Datetime
    , Update_UserName
    , Till_Number
FROM            
    Paid_Out_Tb
WHERE        
    Store_Id = 1929
    AND Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)
    AND Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)
    AND
    (
        Paid_Out_Amount > 50
        OR
        LOWER(Paid_Out_Comment) LIKE '%filter%'
    )

您还需要查看 LIKE 命令 - 更新代码以将注释全部设置为小写并搜索单词过滤器。

另请查看命令 BETWEEN 以进行 Paid_Out_Datetime 检查

AND优先于OR. 如果要控制优先级，则需要对条件进行分组。尝试这个：

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE        (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                     GETDATE()), 0)) AND ( (Paid_Out_Amount > 50) OR
                     (Paid_Out_Comment LIKE N'%' + 'Filter' + '%') )

                         GETDATE()), 0)) AND (Paid_Out_Amount > 20) OR
                         (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')

我结合了您的一些建议，并得出了上述建议。这行得通。谢谢！

尝试以下查询：

SELECT        Store_Id, Paid_Out_Amount, Paid_Out_Comment, Paid_Out_Datetime, Update_UserName, Till_Number
FROM            Paid_Out_Tb
WHERE       ((Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Amount > 50)) OR
                         (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')

您需要将 where 子句的第一部分（直到 'OR'）括在括号中。

(
 (Store_Id = 1929) AND (Paid_Out_Datetime >= DATEADD(day, DATEDIFF(day, 0, GETDATE()) - 1, 0)) AND (Paid_Out_Datetime < DATEADD(day, DATEDIFF(day, 0, 
                         GETDATE()), 0)) AND (Paid_Out_Amount > 50)

) OR (Paid_Out_Comment LIKE N'%' + 'Filter' + '%')
