1. 什么是存储过程?

存储过程是SQL server所提供的Tranact-SQL语言所编写的程序。

2. 如何建立存储过程?

Create Procedure EmployeeID_Orders

@EmployeeID as int

as

select * from orders

where employeeID=@EmployeeID

3. ASP中执行存储过程:

A. 编写sql语句:“execute 存储过程名 参数”,再通过connection.execute或recordset.open执行

strSql="execute employeeID_Orders 1"

Set objRstOrders=objCnnNorthwind.Execute(strSql)

B. 通command对象执行类型为acCmdStoredProc的命令

‘建立Command对象

Set objCmdNorthwind=Server.CreateObject("ADODB.Command")

‘设定命令的文本

objCmdNorthwind.CommandText="EmployeeID_Orders"

‘设定命令的类型

objCmdNorthwind.CommandType=adCmdStoredProc

‘设定命令对象使用的连接对象

Set objCmdNorthwind.ActiveConnection=objCnnNorthwind



‘建立参数对象

Set objParam=objCmdNorthwind.CreateParameter("@EmployeeID",adInteger,adParamInput)

‘把参数对象添加到命令对象的参数集中

objCmdNorthwind.Parameters.Append objParam

‘设定参数的值

objParam.Value=2



‘执行命令对象

Set objRstOrders=objCmdNorthwind.Execute()

‘销毁命令对象

Set objCmdNorthwind=Nothing
