Question

我有一个文本框，用户可以在其中输入酒店名称，然后单击“搜索”按钮。这样做时，应显示具有指定名称的酒店列表。每当我输入酒店名称并单击按钮时，都不会显示任何内容。以下是我的代码，谢谢您的任何建议：

    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    Dim RegDataConn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; data source=" & Server.MapPath("App_Data/1202389.mdb"))

    Dim SearchHotel As String = TBSearch.Text

    Dim cmd As OleDbCommand = New OleDbCommand("SELECT Hotel.Hotel_Name, Hotel.Hotel_Location FROM Hotel WHERE Hotel_Name Like '%" & SearchHotel & "%' ", RegDataConn)
    RegDataConn.Open()
    Dim myDA As OleDbDataAdapter = New OleDbDataAdapter(cmd)
    Dim myDataSet As DataSet = New DataSet()
    myDA.Fill(myDataSet, "Table")
    GridView1.DataSource = myDataSet.Tables("Table").DefaultView



End Sub

Answer 1

尝试在查询中添加加号（+）并在百分号（％）后添加单引号。

 WHERE Hotel_Name Like '%'+" & SearchHotel & "+'%'

VB.net使用文本框搜索数据库
