sql-server - 将 for xml 原始查询的结果写入文件 vb.net

Question

我有一个 for xml 原始选择查询，它返回 server2005 中的 xml 字符串，我想使用 vb.net 将该字符串写入文件。

Answer 1

我发现如果用 sql 的结果填充数据集，第一个单元格就是结果。 我有多慢？!

----------下面的代码--------

   Dim connection As SqlConnection
        Dim adapter As SqlDataAdapter
        Dim ds As New DataSet
        Dim sql As String
        Dim stringxml As String
        Dim SqlCon1 As String = "Data Source=SQLSERVER;Initial Catalog=DATABASE;Integrated Security=SSPI;"
        connection = New SqlConnection(SqlCon1)
        sql = "select * from tblProduct for xml auto"
        Try
            connection.Open()
            adapter = New SqlDataAdapter(sql, SqlCon1)
            adapter.Fill(ds)
            connection.Close()
            stringxml = ds.Tables(0).Rows(0).Item(0)
            Using writer As StreamWriter = New StreamWriter("c:\testings\picktoday.xml")
                writer.Write(stringxml)
            End Using

            MsgBox("Done")
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
