如果你需要一个特定的随机数你可以使用递归CTE:

;WITH A AS (
        SELECT 1 X, RAND() R
    UNION ALL
        SELECT X + 1, RAND(R*100000) --Change the seed
        FROM A
        WHERE X < 1000 --How many random numbers you need
    )
SELECT
    X
    , RAND_BETWEEN_1_AND_14 = FLOOR(R * 14 + 1)
FROM A
OPTION (MAXRECURSION 0) --If you need more than 100 numbers

如果你需要保存你的种子，以便它每次生成“相同”的随机数据，你可以做以下事情:

1. 创建一个返回select rand()的视图

if object_id('cr_sample_randView') is not null
begin
    drop view cr_sample_randView
end
go

create view cr_sample_randView
as
select rand() as random_number
go

2. 创建一个从视图中选择值的UDF。

if object_id('cr_sample_fnPerRowRand') is not null
begin
    drop function cr_sample_fnPerRowRand
end
go

create function cr_sample_fnPerRowRand()
returns float
as
begin
    declare @returnValue float
    select @returnValue = random_number from cr_sample_randView
    return @returnValue
end
go

3.在选择数据之前，输入rand()函数，然后在选择语句中使用UDF。

select rand(200);   -- see the rand() function
with cte(id) as
(select row_number() over(order by object_id) from sys.all_objects)
select 
    id,
    dbo.cr_sample_fnPerRowRand()
from cte
where id <= 1000    -- limit the results to 1000 random numbers

如果你想生成一个1到14之间的随机数。

SELECT CONVERT(int, RAND() * (14 - 1) + 1)

OR

SELECT ABS(CHECKSUM(NewId())) % (14 -1) + 1

RAND(CHECKSUM(NEWID()))

上面将生成一个(伪)随机数，介于0和1之间，不排除。如果在选择中使用，因为种子值每一行都在变化，它将为每一行生成一个新的随机数(但不保证每一行生成一个唯一的数字)。

当与10的上限组合时(产生数字1 - 10):

CAST(RAND(CHECKSUM(NEWID())) * 10 as INT) + 1

生成1000到9999之间的随机数，包括:

FLOOR(RAND(CHECKSUM(NEWID()))*(9999-1000+1)+1000)

"+1" -包含上限值(上例为9999)

您需要为每一行调用RAND()。这里有一个很好的例子
