概要
当您想记录的一个 XML 表示可用于新 ADODB.Stream 对象检索与 XML 字符串。 方法来检索 XML 字符串由记录并不需要使用保存硬盘上保存 ADO 2.5 中。
回到顶端更多信息
要检索 XML for 记录, 请使用以下代码。 一定要有对 " MicrosoftActiveX 数据对象 2.5 库 " 引用。 该代码假定记录是打开和填充。
分析它与 XSL 转换到 ASP 页, 中写出或例如, 可使用您 sXML 字符串。
生成 XML 方法与以下相似。 这是 SQLServer 中 Pubs 数据库中的 Authors 表示例:
Dim oStream As ADODB.Stream
Set oStream = New ADODB.Stream
oRecordset.Save oStream, adPersistXML
Dim sXML As String
sXML = oStream.ReadText
oStream.Close
Set oStream = Nothing
