Question

我有这样的存储过程：

alter procedure [dbo].[testdate]
as  
begin    
   declare @current nvarchar(100),     
           @date1 datetime    

   select @current = getdate()    
   select @date1 = getdate()  
end

执行时我想显示@current和@date1 ..

的值

如何声明这两个变量？

现在我收到0

Answer 1

BEGIN
    DECLARE @curent nvarchar(100),
            @date1 datetime

    SELECT @curent=getdate()
    SELECT @date1=getdate()

    SELECT @curent
    SELECT @date1
END

Answer 2

您应该使用OUTPUT keyword从存储过程中获取这些值

declare
@curent nvarchar(100) OUTPUT,
@date1 datetime OUTPUT

Answer 3

试

alter procedure [dbo].[testdate] as
begin
declare
@curent nvarchar(100),
@date1 datetime
select @curent=getdate()
select @date1=getdate()
select @curent as "CurrentDate"
select @date1 as "Date1"
end

执行存储过程时显示声明的变量值
