NAME
ORLite::PDL - PDL integration for ORLite
SYNOPSIS
package Foo;
# Load database and add statistics package
use ORLite 'statistics.db';
use ORLite::PDL;
my $pdl = Foo->selectcol_pdl('select column from table');
DESCRIPTION
Note: This is a very simple initial implementation, more functionality
to come in the future.
Compressed SQLite database files are a handy format for the distribution
of bulk data, including statistical data.
The ORLite Object-Relational Model provides a convenient way to create
client APIs on top of these databases. However, its numberical analysis
ability is limited to that provided by native SQLite.
The Perl Database Language (PDL) is a high-performance library for
numerical analysis in Perl.
ORLite::PDL provides convenient integration between ORLite and PDL.
METHODS
selectcol_pdl
my $pdl = Foo->selectcol_pdl(
'select col from table where country = ?', {},
'Australia',
);
The "selectcol_pdl" method is added to the root namespace of your ORLite
module tree.
It takes the same parameters and returns the same results as
"selectcol_arrayref", but automatically converts the result to a PDL
"piddle" object.
Returns a PDL object, or throws an exception on error.
