DBD::Pg insert data into an array

[rdfield]

An internet search didn't show up an example of inserting data into a PostgreSQL array (quite a few for retrieving data, though), so I thought I'd post this here.

Given a table:

create table my_table(
id serial,
description varchar(255),
associated_str_data varchar(255)[],
associated_int_data integer[]);

just using arrayrefs for data supplied to the placeholders does the job:

my $desc = "A description";
my @assoc_str_data = ("string 1", "string 2");
my @assoc_int_data = (1,2,3);
$dbh->do("insert into my_table(description, associated_str_data, assoc
+iated_int_data) values (?,?,?)",
         undef, $desc, \@assoc_str_data, \@assoc_int_data);

Checking the result in psql shows the data inserted OK:

# select * from my_table;
 id |  description  |   associated_str_data   | associated_int_data
----+---------------+-------------------------+---------------------
  2 | A description | {"string 1","string 2"} | {1,2,3}
(1 row)
