SQL 服务器函数处理搜索表单提交和 return table 值的逻辑问题

Question

我在 java 网络应用程序中构建了一个搜索表单，如下图所示

现在，此页面的用户需要在 6 个搜索字段中的一个或多个中输入值，或者可以进行开放式搜索，将所有字段留空。

我有以下函数获取结果。

USE [KingsBayY]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

     and ISNULL(tr.Comment,'1')=ISNULL(@attendee,tr.Comment)
     --program
     )
     order by tr.id, tr.time;
RETURN
END

我从这个过程中得到了错误的结果。我注意到的问题是，

无论如何尝试搜索.. 打开搜索，指定一个搜索参数.. 指定多个搜索参数值，程序 return 的所有结果。如何根据使用的搜索参数将其编辑为 return 仅结果？
一些搜索参数可能不完全匹配..例如参加者字段..用户可能输入 'John Doe' 而 table 有参加者列其中一个单元格值为 'John Doe - the genius'.. 我希望能够搜索在单元格值中输入的术语。我该怎么做。

这是catch-all query的一种。

RETURN

备注：

尝试为没有值的字段传递 NULL 而不是 ''。
Stop using the old-style JOIN
也许应该是 ITVF 而不是 MTVF。
