Sql server 这个程序还有其他方法吗？

我在一个表中有7个字段；字段的可能组合会产生一些结果。一个组合可以是1、4、7或全部，依此类推，可以根据客户机的给定动态更改。我必须为它创建一个程序。这些字段是位类型。除了通过If-Else…If-Else定义每个案例外，还有其他方法创建这些程序吗

@Chk_title AS BIT ,
@Chk_Description AS Bit ,
@Chk_Keywords AS BIT,
@Chk_Category AS BIT,
@Chk_Location AS BIT,
@Chk_Source AS BIT,
@Chk_Date AS BIT,
@RD_btn_AND_OR AS BIT

AS

if @RD_btn_AND_OR = 1
Begin
    if  @Chk_title = 1 AND @Chk_Description=1 AND @Chk_Keywords=1 @Chk_Category=1 @ Location=1 @ Chk_Source=1 @Chk_Date=1
        Begin
        Select title, Description, Keywords, category, Location, source, Date from server_des where title Like '%'+@title+'%' AND Description  Like '%'+@Description+'%' AND Keywords Like '%'+@Keywords+'%' AND category Like '%'+@Category+'%' AND Location Like '%'+@Location+'%'AND source Like '%'+@Source+'%' AND Date Like '%'+@Date+'%'
        End
     ELSE if  @Chk_title = 1 AND @Chk_Description = 1 AND @Chk_Keywords = 0 @Chk_Category=1 @ Location=1 @ Chk_Source=1 @Chk_Date=0
        Begin
        Select title, Description, null as'Keywords', category, Location, source, Date from server_des where title Like '%'+@title+'%' AND  Description  Like '%'+@Description+'%' AND category Like '%'+@Category+'%' AND Location Like '%'+@Location+'%' AND source Like '%'+@Source+'%' AND Date Like '%'+@Date+'%'
        End
     ELSE if @Chk_title=0 AND @Chk_Description=1 AND @Chk_Keywords=1  @Chk_Category=1 @ Location=1 @ Chk_Source=0 @Chk_Date=1
        Begin
        Select null as'Title', Description, Keywords, category, Location, source, Date from server_des where  Description  Like '%'+@Description+'%' AND  Keywords Like '%'+@Keywords+'%' AND category Like '%'@Category'%' AND Location Like '%'+@Location+'%' AND source Like '%'+@Source+'%' AND Date Like '%'+@Date+'%'
        End
END

您可以像这样将其全部放在一个语句中，但您应该检查以确保创建的执行计划不会比旧解决方案严重（如果性能对于此存储过程很重要）：

选择标题、描述、关键字、类别、位置、来源、日期
从服务器\u des
其中（@Chk_title 1或类似“%”+@title+'%”的标题）
和（@Chk_Description 1或类似“%”+@Description+'%”的描述）
和（@Chk_关键字1或类似“%+@Keywords+%”的关键字）
和（@Chk_类别1或类似“%”+@Category+'%”的类别）
和（@Chk_位置1或类似“%”+@Location+'%”的位置）
和（@Chk_Source 1或类似于“%”+@Source+“%”的源）
和（@Chk_Data 1或类似于“%”+@Date+%的日期）

您可以基于数据使用动态SQL-编写SQL命令并运行它。像这样：

@Chk_title AS BIT ,
@Chk_Description AS Bit ,
@Chk_Keywords AS BIT,
@Chk_Category AS BIT,
@Chk_Location AS BIT,
@Chk_Source AS BIT,
@Chk_Date AS BIT,
@RD_btn_AND_OR AS BIT

AS

DECLARE @cmdSQL VARCHAR(250)
SET @cmdSQL = 'Select'

if @RD_btn_AND_OR = 1
Begin
    if  @Chk_title <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' title,'
    if  @Chk_Description <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Description,'
    if  @Chk_Keywords <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Keywords,'
    if  @Chk_Category <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Category,'
    if  @Chk_Location <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Location,'
    if  @Chk_Source <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Source,'
    if  @Chk_Date <> 1
        SET @cmdSQL = @cmdSQL + ' null as'
    SET @cmdSQL = @cmdSQL + ' Date'
End

SET @cmdSQL = @cmdSQL + ' from server_des where title Like ''%''+@title+''%'' AND Description  Like ''%''+@Description+''%'' AND Keywords Like ''%''+@Keywords+''%'' AND category Like ''%''+@Category+''%'' AND Location Like ''%''+@Location+''%''AND source Like ''%''+@Source+''%'' AND Date Like ''%''+@Date+''%'''

EXEC(@cmdSQL)
END

@Chk_title作为位，

@Chk_类别作为位，
@Chk_位置作为位，
@Chk_源作为位，

我不明白您所说的“检查以确保创建的执行计划不会比旧解决方案差很多”这句话的意思：“SQL是一种高级、非过程性语言。服务器执行查询所采取的实际步骤由调用查询优化器的组件生成。根据您的服务器设置，查询优化器可能会尝试生成一个适合任何输入值集的计划，如果不同的输入值集显著改变了满足查询所需的工作量，则可能会导致性能下降。@Serg-您好，我是这个网站的新手，所以我不知道如何发布问题直接给你。我已经发布了与此相关的新问题，因为我需要在其中设置格式。你能解决这个问题吗problem@Aishna我想我们可以使用SQL server聊天室-。“还有。”塞格再次感谢你。但我无法访问它，因为我的Stackflow声誉对于该应用程序来说很低。无论如何Thanks@Aishna也许你可以在我的个人资料中看到电子邮件或网站？
