NAME

Patch::DBI::WriteCSV - Patch DBI to also write CSV while fetching rows

VERSION

This document describes version 0.001 of Patch::DBI::WriteCSV (from Perl distribution Patch-DBI-WriteCSV), released on 2018-12-20.

SYNOPSIS

use DBI;
require Patch:DBI::WriteCSV;
my $dbh = DBI->connect("dbi:mysql:database=mydb", "someuser", "somepass");

{
    Patch::DBI::WriteCSV->import; # start writing CSV
    $dbh->selectrow_texttable("SELECT * FROM member");
    Patch::DBI::WriteCSV->unimport; # no longer write CSV
}

The above code will print CSV to STDOUT, e.g.:

Name,Rank,Serial
alice,pvt,123456
bob,cpl,98765321
carol,"brig gen",8745

DESCRIPTION

This package patches the following DBI methods:

fetchrow_array
fetchrow_arrayref
fetchrow_hashref
fetchall_arrayref
fetchall_hashref

to also write CSV while fetching row(s). By default it writes to STDOUT but this can be customized (see "IMPORTS").

IMPORTS

Usage:

Patch::DBI::WriteCSV->import(%opts);

Known options:

  • csv

    A Text::CSV object to use. If not specified, will instantiate a new default one:

    Text::CSV->new

  • handle

    File handle to write CSV to. Defaults to STDOUT if this as well as "filename" is not specified.

  • filename

    File name to open (in append-mode) to write CSV to.
