Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I've enabled DBI trace with level 15 so it shows the full trace but it has no effect.the output remains the same whether level 1 or 99. In particular I'd like to capture the SQL queries with the values interpolated.In other machines I do.In this case I have a CGI script called by Apache which accesses the database and does some queries. It's a bit of an old system with DBI version 1.64. I can't make any modifications to the system because it's production. Do you think it's because of the old DBI version?
