’通用的ASP读取MSSQL存储过程代码示例
’返回临时表记录集
’带传递参数
dim conn,connstr,cmd,rs
connstr = "Provider=SQLOLEDB;server=服务器计算机名或IP地址;uid=用户名;pwd=密码;DATABASE=数据库名称;" ’连接数据库字符串
Set conn = Server.CreateObject("ADODB.Connection") ’创建conn对象
conn.open connstr ’打开数据库
Set Cmd=server.CreateObject("Adodb.Command") ’创建command对象
Cmd.ActiveConnection=conn
Cmd.CommandText="存储过程名" ’调用存储过程名称
Cmd.CommandType=4
cmd.prepared=true
Cmd.Parameters.Append Cmd.CreateParameter("fyear",adInteger,1,2,"2007") ’示例传递给存储过程一个年份,类型是integer,对应存储过程中的fyear变量
Cmd.Parameters.Append Cmd.CreateParameter("myname",adVarChar,adParamInput,50,"阿里西西") ’示例传递给存储过程一个中文字符,类型是varchar,长度为50,对应存储过程中的myname变量
