I am working on an application in asp.net. There is a page to search employee details. User can enter any value to search in multiple fields like
我正在使用asp.net中的应用程序。有一个页面可以搜索员工详细信息。用户可以输入任何值来搜索多个字段,例如
FirstName, LastName, DateOfBirth, EmployeeCode
User can enter value like this:
用户可以输入如下值:
Raj*,1980
That means user want to search Raj*
and 1980
among the number of fields given above.
这意味着用户想要在上面给出的字段数中搜索Raj *和1980。
I was looking at full-text search in SQL Server but the problem is that full-text search does not work for DateTime
columns.
我在SQL Server中查看全文搜索,但问题是全文搜索不适用于DateTime列。
The data can be coming from multiple tables.
数据可以来自多个表。
Please give me any solution.

Why can't you make a "mixed query" like this:
为什么你不能这样做一个“混合查询”:
SELECT * FROM MyTable
WHERE CONTAINS(columnName, '"Toy Dog" OR "live animal"')
AND start_date > ###;
