问题描述

用户输入文本到文本框A中。

功能
在数据库记录中搜索与用户输入相对应的名字和姓氏。

问题：

看来我得到的结果只是搜索名字字段而不是名字和姓氏字段

示例：

* 搜索Mike会返回： * p>

Mike Smith

Mike Jones

搜索Jones：

Mike Jones未被退回

  Protected Sub button1_Click（ByVal sender As Object，ByVal e As EventArgs） Handles button1.Click 
 
 If txtSearch.Text =Then 
 
 Else 
 
 Dim ConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings（ oakfratintdbConnectionString）。ConnectionString 
 Dim Conn As New SqlConnecti （SELECT [FirstName]，[LastName]，[MidInitName]，[NameSuffix]，[NamePrefix]，[DOB]，[DOD]，[BurialDate]，[GeoDirection （[FirstName] LIKE @FirstName），Conn）
 Dim searchDT As DataTable = GetData（searchCMD） ）
 GridView1.DataSource = searchDT 
 GridView1.DataBind（）
 End If 
 
 End Sub 
   
 $ b  代码解释： 
 
 txtSearch是用户的搜索输入
解决方案
更改 
 
 
  SELECT [FirstName]， [LastName]，[MidInitName]，[NameSuffix]，[NamePrefix]，[DOB]，
 [DOD]，[BurialDate]，[GeoDirection]，[Space]，[Lot]，[Row] ]，
 [AddtlInfo] FROM [OFCInterments] WHERE（[FirstName] LIKE @FirstName）
  
到
  SELECT [Fir [姓名]，[姓名]，[姓名]，[出生年]，[$] ，[IntermentSpec]，
 [AddtlInfo] FROM [OFCInterments] WHERE（[FirstName] LIKE @FirstName或
 LastName like @LastName）
  
 
Functionality
User inputs text into textboxA.Search the database records for First Names AND Last Names corresponding to the user's input.
The Problem:
It appears the results I am getting are only searching "First Name" field and not BOTH the First Name and Last Name Fields
Example:
*A search for "Mike" returns:*
Mike Smith
Mike Jones
A search for "Jones":
Mike Jones is not returned
CODE:
Protected Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click

    If txtSearch.Text = "" Then

    Else

        Dim ConnString As String = System.Configuration.ConfigurationManager.ConnectionStrings("oakfratintdbConnectionString").ConnectionString
        Dim Conn As New SqlConnection(ConnString)
        Dim searchCMD As New SqlCommand("SELECT [FirstName], [LastName], [MidInitName], [NameSuffix], [NamePrefix], [DOB], [DOD], [BurialDate], [GeoDirection], [Space], [Lot], [Row], [IntermentSpec], [AddtlInfo] FROM [OFCInterments] WHERE ([FirstName] LIKE @FirstName)", Conn)
        Dim searchDT As DataTable = GetData(searchCMD)
        GridView1.DataSource = searchDT
        GridView1.DataBind()
    End If

End Sub
Code Explanation:
txtSearch is the user's search input
 解决方案 
Change 
SELECT [FirstName], [LastName], [MidInitName], [NameSuffix], [NamePrefix], [DOB], 
[DOD], [BurialDate], [GeoDirection], [Space], [Lot], [Row], [IntermentSpec], 
[AddtlInfo] FROM [OFCInterments] WHERE ([FirstName] LIKE @FirstName)
to 
SELECT [FirstName], [LastName], [MidInitName], [NameSuffix], [NamePrefix], [DOB], 
[DOD], [BurialDate], [GeoDirection], [Space], [Lot], [Row], [IntermentSpec], 
[AddtlInfo] FROM [OFCInterments] WHERE ([FirstName] LIKE @FirstName or 
LastName like @LastName)
