NAME

HashDataRole::Source::DBI - Role to access elements from DBI

VERSION

This document describes version 0.003 of HashDataRole::Source::DBI (from Perl distribution HashDataRoles-Standard), released on 2024-01-15.

DESCRIPTION

This role expects hash data in DBI database table or query.

Note: get_item_at_pos() and has_item_at_pos() are slow (O(n) in worst case) because they iterate. Caching might be added in the future to speed this up.

ROLES MIXED IN

HashDataRole::Spec::Basic

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
