使用Webservice VB.NET從SQL讀取數據

Question

我有一個程序可以使用vb .net Web服務從sql服務器讀取數據，但是在運行這樣的代碼時出現錯誤

http://prntscr.com/apmahp

我的密碼

<WebMethod()> _
Public Function TopKill() As Integer
    Dim con As New SqlConnection
    con.ConnectionString = "Data Source=127.0.0.1;Initial Catalog=RF_User;Integrated Security=True"
    Dim killing As Integer
    con.Open()
    Dim cmd As New SqlCommand(("SELECT TOP 20 Name, [Kill], Death FROM tbl_pvporderview  Join(tbl_base) ON tbl_pvporderview.serial = tbl_base.Serial ORDER BY [Kill] DESC"), con)
    Dim killreader As SqlDataReader
    killreader = cmd.ExecuteReader()
    killreader.Read()
    If killreader.HasRows Then
        killing = killreader.Item("Name").ToString
        killing = killreader.Item("Kill").ToString
        killing = killreader.Item("Death").ToString
    End If
    con.Close()
    Return killing
End Function ' TOP 20 Killer

我不知道如何解決。 任何人都可以幫助我修復我的代碼

之前感謝

Answer 1

注意空格，使用下面的編輯查詢

Dim cmd As New SqlCommand(("SELECT TOP 20 Name, [Kill], Death FROM tbl_pvporderview  Join tbl_base ON tbl_pvporderview.serial = tbl_base.Serial ORDER BY [Kill] DESC"), con)

這應該起作用，因為Join后缺少空格

希望這有所幫助
