NAME

DBIx::Class::Helper::ResultSet::Explain - Get query plan for a ResultSet

SYNOPSIS

This module mostly makes sense to be used without setting as a component:

use Devel::Dwarn;
Dwarn DBIx::Class::ResultSet::Explain::explain($rs)

But as usual, if you prefer to use it as a component here's how:

package MyApp::Schema::ResultSet::Foo;

__PACKAGE__->load_components(qw{Helper::ResultSet::Explain});

...

1;

And then in a script or something:

use Devel::Dwarn;
Dwarn $rs->explain;

DESCRIPTION

This is just a handy little tool that gives you the query plan for a given ResultSet. The output is in no way normalized, so just treat it as a debug tool or something. The only supported DB's are those listed below. Have fun!

See "NOTE" in DBIx::Class::Helper::ResultSet for a nice way to apply it to your entire schema.

EXAMPLE OUTPUT FROM SUPPORTED DB's

SQlite

Pg

mysql
