What would be the best query

To check whether the box_id "2" has ANY records, that have ANY records with the same box_val as box_id "1"

Using only one query, rather than looping through all records where box_id = 2 then checking for match



box_id | box_val
________________________
1 | 25
1 | 74
1 | 54
2 | 25
2 | 35



Thanks!
