my $query = qq{INSERT INTO some_table (id,$fieldList) VALUES (id,$field_placeholders)};

Side comment: Dynamic SQL is not secure. Admittedly, this one is more interesting in that it actually uses placeholders, but, building the placeholders string kind of defeats the purpose. That is, there's a benefit that strings need not be escaped and there will be strong typing, but the statement is no more secure.

If you're just doing an import, mysql supports it directly with LOAD DATA INFILE.
