从查询中排除日期

Question

如果我想在下面的查询中排除某些日期，我该怎么做呢。我想排除日期为25/12/2014的日期。

SELECT *,
    (DATEDIFF(dd, [1], next_service)) - (DATEDIFF(wk, [1], next_service) * 2) - (
        CASE 
            WHEN DATENAME(dw, [1]) = 'Sunday'
                THEN 1
            ELSE 0
            END
        ) - (
        CASE 
            WHEN DATENAME(dw, [1]) = 'Saturday'
                THEN 1
            ELSE 0
            END
        ) AS days_diff_1,
    (DATEDIFF(dd, [2], next_service)) - (DATEDIFF(wk, [2], next_service) * 2) - (
        CASE 
            WHEN DATENAME(dw, [2]) = 'Sunday'
                THEN 1

FROM #rk_ap_pivot

只需在WHERE datefield <> '2014-12-25'之后添加FROM #rk_ap_pivot。
