'-----建立Connection对象----------
set objCnn=Server.CreateObject("Adodb.connection")

'-----建立Command对象-----------

1，调用没有参数的存储过程
<%
set conn=server.CreateObject("adodb.connection")
set cmd=server.CreateObject("adodb.command")
strconn="dsn=pubs;uid=sa;pwd"
conn.Open strconn
set cmd.ActiveConnection=conn

cmd.CommandText="{call nono}"

'set rs=cmc.exe 或者cmd.execute

set rs=cmd.Execute()

%>
2，一个输入的参数的存储过程
<%
set conn=server.CreateObject("adodb.connection")
set cmd=server.CreateObject("adodb.command")
strconn="dsn=pubs;uid=sa;pwd"

conn.Open strconn
set cmd.ActiveConnection=conn

cmd.CommandText="{call oneinput(?)}"
cmd.Parameters.Append cmd.CreateParameter("@aaa",adInteger ,adParamInput )
cmd("@aaa")=100

cmd.Execute()

%>
3，一个输入参数和一个输出的参数
<%
set conn=server.CreateObject("adodb.connection")
set cmd=server.CreateObject("adodb.command")
strconn="dsn=pubs;uid=sa;pwd"

conn.Open strconn
set cmd.ActiveConnection=conn

cmd.CommandText = "{call oneinout(?,?)}"
cmd.Parameters.Append cmd.CreateParameter("@aaa",adInteger,adParamInput)
cmd("@aaa")=10
cmd.Parameters.Append cmd.CreateParameter("@bbb",adInteger,adParamOutput)

cmd.Execute()

bbb=cmd("@bbb")
%>
4，一个输入参数，一个输出参数，和一个返回值
<%
set conn=server.CreateObject("adodb.connection")
set cmd=server.CreateObject("adodb.command")
strconn="dsn=pubs;uid=sa;pwd"

conn.Open strconn
set cmd.ActiveConnection=conn

cmd.CommandText="{?=call onereturn(?,?)}"

cmd.Parameters.Append cmd.CreateParameter("@return_value",adInteger,adParamReturnValue )
cmd.Parameters.Append cmd.CreateParameter("@aaa",adInteger,adParamInput )
cmd("@aaa")=10
cmd.Parameters.Append cmd.CreateParameter("@bbb",adInteger,adParamOutput)

cmd.Execute()

bbb=cmd("@bbb")
rrr=cmd("@return_value")
%>
