Question

我想调用一个存储过程，它接受两个参数（用户名和密码）并返回两个int类型的值（'result'和'group'）'result'来检查用户是否有效'' group'只显示客户的群组数量有三种类型的群体组＃1：管理员用户组＃2：自定义用户 grpup＃3：特殊用户

下面是我当前的代码，它只返回结果

ALTER PROCEDURE [dbo].[suserpass] 
@username Varchar(50), 
@password varchar(50), 
@result int OUTPUT,
@group int OUTPUT

AS
IF EXISTS (select [user]   from [userpassTable] where [user] = @username and [pass]=@password) 
  set @result=1  

else 
  set @result=0

感谢

设置两个输出参数。

你可以这样做：

IF EXISTS (SELECT [user] FROM [userpassTable] 
           WHERE [user] = @username AND [pass] = @password) 
BEGIN
  SELECT @result=1 , @group = group
  FROM [userpassTable] 
  WHERE [user] = @username
END
else 
BEGIN
  SELECT @result=0 , @group = 0 -- group 0 doesn't exist, used as user does exist
END

为了便于阅读，我添加了BEGIN/END块，并允许多个语句。

在您的C＃中，@result和@group都应设置为输出参数。

你需要做一些如下所示的事情，你需要设置两个输出变量来完成你的任务......

  ALTER PROCEDURE [dbo].[suserpass] 
    @username Varchar(50), 
    @password varchar(50), 
    @result int OUTPUT,
    @group int OUTPUT

    AS
    IF EXISTS (select [user]   from [userpassTable] where [user] = @username and [pass]=@password) 
    begin
      select @result=1
      select @group = usergroup from [userpassTable] where [user] = @username and [pass]=@password  
    end 
    else
    begin 
      select @result=0
      select @group=0
    end

我想，从概念上讲，你正在寻找类似的东西（尚未测试代码）：

ALTER PROCEDURE [dbo].[suserpass] 
@username Varchar(50), 
@password varchar(50), 
@result int OUTPUT,
@group int OUTPUT

AS
IF EXISTS (select [user] from [userpassTable] where [user] = @username and [pass] = @password) 
  BEGIN
    set @result = 1
    set @group = (select (top 1) [groupType] from [userGroupTable] where [user] = @username)
  END
else     
  set @result=0

需要从c＃中的存储过程返回两个值
