How to check if an int contains another one as part of it?

The question is fairly clear. I wanna check if for example a number x is contained in another number y. And I wanna do it in SQL (also in LINQ if possible). Additionally those integer values(y values) are Ids from a table. So when LINQ is concerned, I am not looking for some general solution like:

int y=123,x=32;
bool isContainedInY = y.ToString().Contains(x.ToString());

Examples:

x = 5, y = 1256 => true
x = 384, y = 38412 => true
x = 1, y = 5236 => false

Answers can be based on a table like the following:

+------+-------+
| Id   | Name  | 
+------+-------+
| 52   | Lola  | 
| 65   | Dolly | 
| 88   | Wolly |
| 102  | Sorry |
+------+-------+

Answer

You can cast them to varchar first

SELECT CHARINDEX(STR(x), STR(y)) > 0
