具有条件“和”逻辑的Transact-SQL存储过程

我正在开发一个存储过程，用于根据用户输入的条件过滤网格。在可能的标准中，他们可以选择查看在某个开始日期和结束日期之间完成的事务。我将4个输入参数传递给proc-@ClientKey，即请求信息的客户端，@FilterBy这是从ASP.NET中的下拉列表中选择的值，本质上告诉proc用户是否选择按名称、地址、日期等进行筛选。在这种情况下，日期的@FilterBy值为5，@Value1，在本例中是开始日期，在本例中是结束日期的@Value2

在伪代码中，我想要的是：

选择列的相邻部分 从一些连接表 哪里有标准 和过滤比的情况

当5时，则d.TransactionTime>=CAST@Value1日期和d.TransactionTime您是指以下内容吗？ 你可能会发现这也很有用。 我还没有测试过代码，只是提出了一个想法——写这样的代码对我来说总是错的——也许有人能提供更好的

CREATE PROC MyProc

    @ClientKey  int,
    @FilterBy   int,
    @Value1 varchar(150),
    @Value2 varchar(150)
--  NB WITH RECOMPILE, see link (above)
WITH RECOMPILE AS
BEGIN
    SET NOCOUNT ON;

    SELECT *
    FROM ...
    WHERE 
        Col1    =   CASE 
                        WHEN @FilterBy = 1 THEN @Value1
                        ELSE Col1
                    END
    AND
        1       =   CASE
                        WHEN @FilterBy = 2 AND Col2 > @Value1 AND Col3 < @Value2        THEN 1
                        WHEN @FilterBy = 2 AND NOT (Col2 > @Value1 AND Col3 < @Value2)  THEN 0
                        ELSE 1
                    END 
END

或当@FilterBy=5且d.TransactionTime介于CAST@Value1作为日期和CAST@Value2AS DATE THEN 1 ELSE 0 END=1的工作原理相同，但两者之间的值使代码更具可读性。这只是个人喜好，在执行上没有区别。事实上，在完成另一个系统增强之前，我只做了短暂的测试。现在我回到这里，proc似乎没有返回除5之外的任何与@FilterBy值对应的行。不知道为什么。对于*除5以外的任何@FilterBy值。@Mike我只关注where中的问题区域部分。似乎您需要先使用和@FilterBy或第二个@FilterBy或。。。。。在任何情况下，我都没有检查所有的过滤器谢谢拉马克-了解重点范围。还没有快乐，但仍在努力。
