在asp.net中使用sql server存储过程 (包括SqlDataAdapter调用存储过程)

数据库名称:company,

表名:company.dbo.department

存储过程的定义:

//获取所有department信息
create proc getalldep
as
select * from company.dbo.department
//插入一个department
create proc insertdep
@ID int output,
@Name varchar(50)
as
insert into company.dbo.department
(Name) values(@Name);
set @ID=@@IDENTITY

下面是在asp.net中使用,新建一个类 ,比如department.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.SqlClient;
using System.Data;
namespace WebApplication7
{
public class department
{
private string constring;
public Emp()
{
constring = "Data Source=localhost;Initial Catalog=company;user id=tt;password=y357395775@;";
}
public Emp(string connectionstring)
{
constring = connectionstring;
}
public int insertemp(string name)
{
SqlConnection con = new SqlConnection(constring);
SqlCommand cmd = new SqlCommand("insertdep", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@Name", SqlDbType.VarChar, 50));
cmd.Parameters["@Name"].Value = name;
cmd.Parameters.Add(new SqlParameter("@ID", SqlDbType.Int));
cmd.Parameters["@ID"].Direction = ParameterDirection.Output;
try
{
con.Open();
cmd.ExecuteNonQuery();
return (int)cmd.Parameters["@ID"].Value;
}
catch (SqlException exc)
{
Console.Write(exc.Message.ToString());
}
finally
{
con.Close();
}
}

public DataTable getalldep()
{
SqlConnection con = new SqlConnection(constring);
SqlCommand cmd = new SqlCommand("getalldep", con);
cmd.CommandType = CommandType.StoredProcedure;
DataSet ds=new DataSet();
SqlDataAdapter da=new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(ds, "dep");
return ds.Tables["dep"];
}
}
}

然后在页面上新建一个gridview控件引用之

protected void Page_Load(object sender, EventArgs e)
{
department dep = new department();
gvdep.DataSource = dep.getalldep();
gvdep.DataBind();
}
//gridview控件的id为gvdep

这里只是实现了getalldep的使用.

需要注意的是SqlDataAdapter类对存储过程的调用过程:

SqlConnection con = new SqlConnection(constring);
SqlCommand cmd = new SqlCommand("getalldep", con);
cmd.CommandType = CommandType.StoredProcedure;
DataSet ds=new DataSet();
SqlDataAdapter da=new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(ds, "dep");
return ds.Tables["dep"];
