数据库结构操作。适应于access，sql server等常见的数据库。

1。建立连接。
可以通过ODBC或OLEDB连接。
Set gObjDC = Server.CreateObject("ADODB.Connection")
dim strconn,myDSN
myDSN="test"
strconn="DSN="&myDSN&";uid=sa;pwd="
'strconn ="Provider=SQLOLEDB.1;Persist Security Info=True;User ID=sa;Initial Catalog=MeiSha;Data Source=tonny"
gObjDC.ConnectionString=strconn
gObjDC.Open

2。显示所有表
set gObjRS = gObjDC.OpenSchema(adSchemaTables)
Do While Not gObjRS.EOF
If gObjRS.Fields("TABLE_TYPE") = "TABLE" AND Left(gObjRS.Fields("TABLE_NAME"), 4) <> "MSys" Then
'不必把系统表显示出来
Response.Write ""
Response.Write "" & gObjRS.Fields("TABLE_NAME") & ""
myPLink = "?DSN_NAME=" & myDSN & "&Table_Name=" & gObjRS.Fields("TABLE_NAME")
Response.Write " gObjDC.execute mySQLQueryString
