I am wondering what would be the most efficient way to use perl to query a mysql table that will result in a full table scan.

Let's say I have 1 million rows and I need to search on a non-indexed column for a substring.

Which would be more efficient:
1. limiting the query result with mysql "where <column> like '%substring%'"
2. get full table in query result and then loop through result, matching substring using a perlre?


Both will result in a full table scan, right? So, I guess the question really is which of mysql or perl is the most efficient in matching substrings?
