NAME

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

VERSION

This document describes version 0.001 of HashDataRole::Source::DBI (from Perl distribution HashDataRoles-Standard), released on 2021-05-21.

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.
