asp 获取access系统表，查询等操作代码

方法一：直接用ado的OpenSchema()方法打开adSchemaTables，建立一个schema记录集

Code:
<%
Const adSchemaTables = 20
adSchemaColumns = 4
dim Conn,db
dim ConnStr
db="temp.mdb"       'ACCESS数据库的文件名，请使用相对于网站根目录的的绝对路径
ConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath(db)
Set conn = Server.CreateObject("ADODB.Connection")
conn.Open connstr

Dim rstSchema
Dim I

Set rstSchema = Conn.OpenSchema(adSchemaTables)

Do while not rstSchema.EOF
  response.write("Table name: "& rstSchema("TABLE_NAME") & vbCr & _
  "Table type: " & rstSchema("TABLE_TYPE") & vbCr)
response.write("<br/>")
I = I + 1
rstSchema.MoveNext
Loop
rstSchema.Close

conn.Close
%>

方法二：Access 系统表 MsysObjects 包含了数据库对象列表。尽管未在文档中记载，你仍可通过查询它来获取你想要的。但是默认情况下无法操作系统表，必须手动设定权限收才能查询系统表。
请参考以下动画：如何获取对msysobject的操作权限 http://blog.iyi.cn/user/david/archives/IMAGES/msobject.swf

但是我在access2003中找不到这几个系统表，不知道是不是m$增强了access的安全性。

使用下列 SQL 语句来获取你想要的

Code:
查询:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=5 ORDER BY MSysObjects.Name;

窗体:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=-32768 ORDER BY MSysObjects.Name;

表:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (Left$([Name],4) <> "Msys") AND (MSysObjects.Type)=1 ORDER BY MSysObjects.Name;

报表:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32764 ORDER BY MSysObjects.Name;

模块:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32761 ORDER BY MSysObjects.Name;

宏:
SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32766 ORDER BY MSysObjects.Name;
