PERL export multiple query results to a JSON file

I'm trying to export multiple query results to a json file, the below code exports the results of the querys to a single json file but since Its two separate print statements the json is not correct. ][ separates the query results in the json file.

#!/usr/bin/perl -w
use DBIx::JSON;
use strict;

my $driver = "mysql"; 
my $database = "testdb";
my $dsn = "dbname=$database;host=;port=3306";
my $userid = "test";
my $password = "password";

my $testcase1_count = "SELECT COUNT(odi_id) as testcase1_count from Orders.order_item oi inner join Orders.order_header oh ON oi.ord_id=oh.ord_id
where oh.ord_status_id<>'X' ";

my $testcase2_count = "SELECT COUNT(odi_id) as testcase2_count from Orders.order_item oi inner join Orders.order_header oh ON oi.ord_id=oh.ord_id
where oh.ord_status_id<>'R' ";

open STDOUT, '>', "/var/www/test/data/kpi_dashboard_data_1hr.json";
my $obj = DBIx::JSON->new($dsn, "mysql", $userid, $password);
 $obj->do_select($testcase1_count, "testcase1_count", 1);
print $obj->get_json;
 $obj->do_select($testcase2_count, "testcase2_count", 1);
print $obj->get_json;
$obj->err && die $obj->errstr;

Open in new window

returns the below in kpi_dashboard_data_1hr.json

I'm assuming I could use a SED statement in the perl to replace the ][ with a comma in the json file but there has to be a better way?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I have not done any testing, but my first though would be to push them onto an array then strip off the outer brackets and use a join statement when outputting to the file.
$obj->do_select($testcase1_count, "testcase1_count", 1);
push @jason, $obj->get_json;

$obj->do_select($testcase2_count, "testcase2_count", 1);
push @jason, $obj->get_json;

s/^\[|\]$//g for @jason;

print '[' . join(',', @jason) . ']';
