如果你不需要它是一个整数，而是任何随机的唯一标识符，你可以使用newid()

SELECT table_name, newid() magic_number 
FROM information_schema.tables

当在单个批处理中多次调用rand()时，将返回相同的数字。

我建议使用convert(varbinary,newid())作为种子参数:

SELECT table_name, 1.0 + floor(14 * RAND(convert(varbinary, newid()))) magic_number 
FROM information_schema.tables

Newid()保证每次调用都会返回不同的值，即使是在同一个批处理中，因此将它作为种子将提示rand()每次给出不同的值。

编辑以获得从1到14的随机整数。

您需要为每一行调用RAND()。这里有一个很好的例子

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

您是否在每一行中都有一个整数值，可以作为种子传递给RAND函数?

要得到1到14之间的整数，我相信这是可行的:

FLOOR( RAND(<yourseed>) * 14) + 1
