OpenSchema方法技术探讨（二）

利用openschema可以获得所有表的主键，当然这只是它的很多功能中的一个。

connstr = "Provider=MSDAORA.1;User ID=liujincai;password=ljc1001;Data Source=hp1"

set mm=server.CreateObject("adodb.connection")

mm.Open connstr

Const adSchemaPrimaryKeys = 28

set rs=mm.OpenSchema(adSchemaPrimaryKeys)

Response.Write "<table>"

Response.Write "<TR>"

for i=0 to rs.fields.count-1

Response.Write "<td>" & rs(i).name & "</td>"

next

Response.Write "</tr> "

do while not rs.eof

Response.Write "<tr>"

for i=0 to rs.fields.count-1

Response.Write "<td>" & rs(i) & "</td>"

next

Response.Write "</tr> "

rs.movenext

loop

Response.write “</table>“

'下面的语句获得表'TB_HOUSE_MAIN'的主键所在的字段

rs.Filter="TABLE_NAME='TB_HOUSE_MAIN'"

if not(rs.eof and rs.bof) then Response.Write rs("COLUMN_NAME")
