asp连接sql数据库的方法有四种，如下：

第一种写法：

MM_conn_STRING = "Driver={SQLServer};server=(local);uid=sa;pwd=;database=infs;"
Set conn = Server.Createobject("ADODB.Connection")
conn.open MM_conn_STRING
SET RS=SERVER.CreateObject("ADOBD.recordset")
SQL="SELECT * FROM TABLE ORDER BY ID DESC"
RS.open SQL,CONN,3,3

第二种写法：（DSN连接）

MM_conn_STRING="DSN=BBS;UID=SA;PWD=12345"
Set conn = Server.Createobject("ADODB.Connection")
conn.open MM_conn_STRING
SET RS=SERVER.CreateObject("ADOBD.recordset")
SQL="SELECT * FROM TABLE ORDER BY ID DESC"
RS.open SQL,CONN,3,3  // 3,3是修改、删除、增加开关！

第三种写法：

MM_conn_STRING_own = "Driver={SQLServer};server=(local);uid=sa;pwd=11111;database=infs;"
Set conn = Server.Createobject("ADODB.Connection")
conn.open MM_conn_STRING_own

第四种：这种方法用在ACCESS中

strconn = "DRIVER=Microsoft Access Driver (*.mdb);DBQ=" _
& Server.MapPath("asp.mdb")
set conn = server.createobject("adodb.connection")
conn.open strconn
