SQL語句生成指定范圍內隨機數

1、生成隨機實型數據

create procedure awf_RandDouble 
   @min dec(14,2),
   @max dec(14,2), 
   @result dec(14,2) output
as 
begin
	set @result= cast((rand()*(@max-@min)+@min) as dec(14,2))
    return @result
end

　　

2、生成隨機整型數據

create procedure awf_RandInt 
   @min int,
   @max int, 
   @result int output
as 
begin
	set @result= cast((rand()*(@max-@min)+@min) as int)
    return @result
end
