How can I print the SQL query executed after Perl's DBI fills in the placeholders?

Question

I\'m using Perl\'s DBI module. I prepare a statement using placeholders, then execute the query.

Is it possible to print out the final query that was executed without ma

See Tracing in DBI. The following works using DBD::SQLite but produces a lot of output:

$dbh->trace($dbh->parse_trace_flags('SQL|1|test'));

Output:

<- prepare('SELECT ... FROM ... WHERE ... = ?')= DBI::st=HASH(0x21ee924) at booklet-excel.pl line 213

<- execute('Inhaler')= '0E0' at booklet-excel.pl line 215

etc etc.

You could plug your own filter in to the trace stream to only keep prepares.
