EF执行存储过程

//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");
}
