Search value in column which is pipe separated in sql

Question

I want to search value which is pipe-separated in column. See below.

Column1 
1
1|2|23
2
6
6|12

I want to search 2 in all rows so it will return below rows

Column1
1|2|23
2

Can anyone please tell me how can we achieve this?

Answer 1

你可以使用like:

where '|'+column1+'|' like '%|2|%'

通过包含额外的分隔符,您可以避免"2"匹配"23".
