>From perldoc DBI:

"PrintError" (boolean, inherited)
The "PrintError" attribute can be used to force errors to
generate warnings (using "warn") in addition to returning
error codes in
the normal way. When set "on", any method which results in
an error occuring will cause the DBI to effectively do a
"warn("$class $method failed: $DBI::errstr")" where $class
is the driver class and $method is the name of the method
which failed. E.g.,
...
By default, "DBI->connect" sets "PrintError" "on".

If desired, the warnings can be caught and processed using a
$SIG{__WARN__} handler or modules like CGI::Carp and CGI::ErrorWrap.

is this what you want ?

it seems that the error messages go to STDERR, not STDOUT.
maybe a 2> error.log ?
