EF执行存储过程与执行Sql语句非常类似，insert、delete、update操作通过ExecuteSqlCommand()执行，select操作通过SqlQuery<Sys_User>()执行。

一、执行insert存储过程（无返回值）

CREATE PROCEDURE [dbo].[proc_AddSysUser01]
	@Name nvarchar(50),
	@Phone nvarchar(50)
AS
BEGIN
	--SET NOCOUNT ON;

    -- Insert statements for procedure here
	insert into Sys_User values(@Name,@Phone,'耶路撒冷',GETDATE())
END

public ActionResult ExecuteInsertProc(string name, string phone)
{
    using(NHibernateContext context = new NHibernateContext())
    {
        SqlParameter pp_name = new SqlParameter("@Name", name);
        SqlParameter pp_phone = new SqlParameter("@Phone", phone);
        int count = context.Database.ExecuteSqlCommand("exec [proc_AddSysUser01] @Name,@Phone", pp_name, pp_phone);
        context.SaveChanges();
    }
    return View("Index");
}

二、执行insert存储过程（out参数返回主键）

CREATE PROCEDURE [dbo].[proc_AddSysUser02]
	@Name nvarchar(50),
	@Phone nvarchar(50),
	@Id int output
AS
BEGIN
	--SET NOCOUNT ON;

        -- Insert statements for procedure here
	insert into Sys_User values (@Name,@Phone,'安曼酒店',GETDATE());
	select @Id=SCOPE_IDENTITY();
END

public ActionResult ExecuteInsertProc(string name, string phone)
{    
    using (NHibernateContext context = new NHibernateContext())
    {
        SqlParameter pp_id = new SqlParameter("@Id", SqlDbType.Int);
        pp_id.Direction = ParameterDirection.Output;
        SqlParameter pp_name = new SqlParameter("@Name", name);
        SqlParameter pp_phone = new SqlParameter("@Phone", phone);
        //count值为1，out参数需要放在最后
        int count = context.Database.ExecuteSqlCommand("exec [proc_AddSysUser02] @Name,@Phone,@Id out", pp_id, pp_name, pp_phone);
        //id值为10010
        int id = int.Parse(pp_id.Value.ToString());
        context.SaveChanges();
    }
    return View("Index");
}

三、执行delete存储过程

CREATE PROCEDURE [dbo].[proc_DeleteSysUser]
	@Id int,
	@Name nvarchar(50)
AS
BEGIN
	--SET NOCOUNT ON;

        -- Insert statements for procedure here
	delete from Sys_User where Id>@Id and Name like '%'+@Name+'%'
END

public ActionResult ExecuteDeleteProc(int id, string name)
{
    using (NHibernateContext context = new NHibernateContext())
    {
        SqlParameter pp_id = new SqlParameter("@Id", id);
        SqlParameter pp_name = new SqlParameter("@Name", name);
        //count值为2
        int count = context.Database.ExecuteSqlCommand("exec [proc_DeleteSysUser] @Id,@Name", pp_id, pp_name);
        context.SaveChanges();
    }
    return View("Index");
}

四、执行update存储过程

CREATE PROCEDURE [dbo].[proc_UpdateSysUser]
	@Id int,
	@Name nvarchar(50),
	@Phone nvarchar(50)
AS
BEGIN
	--SET NOCOUNT ON;

        -- Insert statements for procedure here
	update Sys_User set Phone=@Phone where Id>@Id and Name like '%'+@Name+'%'
END

public ActionResult ExecuteUpdateProc(int id, string name, string phone)
{
    using (NHibernateContext context = new NHibernateContext())
    {
        SqlParameter pp_id = new SqlParameter("@Id", id);
        SqlParameter pp_name = new SqlParameter("@Name", name);
        SqlParameter pp_phone = new SqlParameter("@Phone", phone);
        //count值为2
        int count = context.Database.ExecuteSqlCommand("exec [proc_UpdateSysUser] @Id,@Name,@Phone", pp_id, pp_name, pp_phone);
        context.SaveChanges();
    }
    return View("Index");
}

五、执行select存储过程

CREATE PROCEDURE [dbo].[proc_GetSysUser] 
	@Id int,
	@Name nvarchar(50)
AS
BEGIN
	SET NOCOUNT ON;

        -- Insert statements for procedure here
	select * from Sys_User where Id<@Id and Name like '%'+@Name+'%'
END

public ActionResult ExecuteSelectProc(int id, string name)
{
    using (NHibernateContext context = new NHibernateContext())
    {
        SqlParameter pp_id = new SqlParameter("@Id", id);
        SqlParameter pp_name = new SqlParameter("@Name", name);
        //userList.Count值为96
        List<Sys_User> userList = context.Database.SqlQuery<Sys_User>("exec [proc_GetSysUser] @Id,@Name", pp_id, pp_name).Cast<Sys_User>().ToList();                
        context.SaveChanges();
    }
    return View("Index");
}
