范围内的日期问题

Question

鉴于以下 SQL，我遇到了一个问题：根据开始日期 (@fi) 和结束日期 (@ff)，有时 returns 值，有时不是。

例如： 1) 如果@fi 和@ff 是 '01/01/2014' -> ok

         2)if @fi and @ff are '01/01/2015' -> ok
         3)if @fi and @ff are '31/12/2014' -> no rows
         4)if @fi = '31/12/2014' and @ff = '01/01/2015' -> ok (but returns more rows than the second case, that is, there should be results for the third case).
I've tried with BETWEEN clause, with the same result. I checked (in the 3rd case) if the is included in that range (with an if-else), and yes, it is. Any clue?

提前致谢。问候。

declare @fi date,
    @ff date

    set @fi = '31/12/2014'
    set @ff = '01/01/2015'

Answer 1

用这个替换你的 where 子句。

  WHERE     (( TM2000_RegistroGeneral.FechaDocumento >= @fi
              AND TM2000_RegistroGeneral.FechaDocumento <= @ff )


        OR ( TM2000_RegistroGeneral.FechaDocumento >= DATEADD(YEAR, -1, @fi)
                 AND TM2000_RegistroGeneral.FechaDocumento <= DATEADD(YEAR, -1, @ff) )

        OR ( TM2000_RegistroGeneral.FechaDocumento >= DATEADD(YEAR, -2, @fi)
                 AND TM2000_RegistroGeneral.FechaDocumento <= DATEADD(YEAR, -2, @ff) )

        OR ( TM2000_RegistroGeneral.FechaDocumento >= DATEADD(YEAR, -3, @fi)
                 AND TM2000_RegistroGeneral.FechaDocumento <= DATEADD(YEAR, -3, @ff) )

        OR ( TM2000_RegistroGeneral.FechaDocumento >= DATEADD(YEAR, -4, @fi)
                 AND TM2000_RegistroGeneral.FechaDocumento <= DATEADD(YEAR, -4, @ff) )
            )
            AND ( ISNULL(TM2000_Asuntos.CodigoNulo, 0) = 0 )

我相信您的 OR & AND 相互冲突并且您不必要地重复了 AND 子句

Answer 2

在 WHERE 子句中比较时使用 CAST(DATE, TM2000_RegistroGeneral.FechaDocumento) 解决了问题。

FechaDocumento 是 DATETIME，因此需要转换。

谢谢！
