需要两个来自存储过程的返回值在c＃

Question

我想调用一个存储过程，它需要两个参数（用户名&密码）并返回两个值类型int（'result'和'group'）'result'用于检查用户是否有效或不和“组”只是表明用户的组号 有三种类型组 组＃1：admin用户 组＃2：自定义用户 grpup＃3：特殊用户

下面是我目前的代码，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 

谢谢

Answer 1

你需要为下面你需要设置两个输出变量，会做你的任务做soemthing .....

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

设置两个输出参数。

你可以这样说：

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 

我已经添加了可读性BEGIN/END块，并允许多个语句。

在C＃都@result和@group应设置为输出参数。

我想的是，在概念上，您正在寻找这样的事情（避风港“T测试的代码）：

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
