以下是SQL中两个存储过程: CREATE PROCEDURE dbo.oa_selectalluser AS select * from UserInfo GO CREATE PROCEDURE dbo.oa_SelectByID @id int AS select * from UserInfo where ID=@id GO
(一).不带参数的存储过程: protected void Page_Load(object sender, EventArgs e) ...{ if(!Page.IsPostBack) ...{ //不带参数的存储过程的使用方法 SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["oaConnectionString"].ToString()); SqlDataAdapter da = new SqlDataAdapter(); DataSet ds=new DataSet(); da.SelectCommand = new SqlCommand(); da.SelectCommand.Connection = conn; da.SelectCommand.CommandText = "oa_SelectAllUser"; da.SelectCommand.CommandType = CommandType.StoredProcedure; da.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind(); } 在页面中添加了一个GridView控件用来绑定执行存储过程得到的结果. (二).带参数的存储过程: protected void btn_search_Click(object sender, EventArgs e) ...{ //带参数的存储过程的使用方法 SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["oaConnectionString"].ToString()); SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = new SqlCommand(); da.SelectCommand.Connection = conn; da.SelectCommand.CommandText = "oa_SelectByID"; da.SelectCommand.CommandType = CommandType.StoredProcedure;
param.Direction = ParameterDirection.Input; param.Value = Convert.ToInt32(txt_value.Text); da.SelectCommand.Parameters.Add(param);
GridView1.DataSource = ds; GridView1.DataBind(); } 同样,在页面中添加了一个GridView控件用来绑定执行存储过程的结果,另外,在页面中还添加了一个textbox控件和一个BUTTON按钮,上面的执行存储过程是放在按钮的onclick事件中的.textbox控件用来接收存储过程的参数 (责任编辑:admin) |
