SQL query to find the nearest element for list of numbers in an array

Question

我有一个包含数字列表的数组，例如：[20,10,40,10,15]，如何使用SQL查询在此数组中找到最近的元素？

Answer 1

lets assume you have table values like: id|value and need to find value closest to 5

then

SELECT value from values where abs(value - 5) = (select min(abs(value -5)) from values)
