vb.net 如何与oracle数据库连接

答案：在web.config中配置：
  <connectionStrings>
    <add name="conn" connectionString ="Provider=服务器名;Data Source=数据库名;User ID=用户名;Password=密码;"/>
  </connectionStrings>
’连接Oracle
 Dim strConnect As String = System.Web.Configuration.WebConfigurationManager.ConnectionStrings("conn").ToString()
    Dim conn As OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(strConnect)
’返回数据
    Public Function getTable(ByVal sql)
        conn.Open()
        Dim comm As OleDb.OleDbCommand = New OleDb.OleDbCommand(sql, conn)
        Dim da As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter(comm)
        Dim dt As System.Data.DataTable = New System.Data.DataTable()
        da.Fill(dt)
        conn.Close()
        Return dt
    End Function
’返回受影响的行数
    Public Function impactDate(ByVal sql)
        conn.Open()
        Dim comm As OleDb.OleDbCommand = New OleDb.OleDbCommand(sql, conn)
        Dim i As Integer = comm.ExecuteNonQuery
        Return i
    End Function
