in thread Multiple queries on DBI corresponding to multiple csv files?

Which version of DBI are you running? select_array was added in v1.635, 24/04/2016.

Update: from the command line, get DBI version: perl -MDBI -e 'print $DBI::VERSION'

    DBI Version: 1.627

    That explains a lot. Is there any other way to do it without update the DBI?

      The documentation points out that it is just a "convenience wrapper" so you could simply call the underlying method instead and then de-reference.
