NAME

DBIO::Firebird::Introspect::Uniques - Introspect Firebird UNIQUE constraints via rdb$relation_constraints

VERSION

version 0.900000

DESCRIPTION

Fetches UNIQUE constraint metadata via rdb$relation_constraints joined against rdb$index_segments. This is distinct from DBIO::Firebird::Introspect::Indexes, which deliberately excludes constraint-backed indexes: a Firebird UNIQUE constraint and a standalone CREATE UNIQUE INDEX are different objects, and only the former belongs in the normalized table_uniq_info generation contract.

METHODS

fetch

my $uniques = DBIO::Firebird::Introspect::Uniques->fetch($dbh, $tables);

Given the tables hashref from DBIO::Firebird::Introspect::Tables, returns a hashref keyed by table name. Each value is an arrayref of [ $constraint_name, \@column_names ] pairs (columns in rdb$field_position order), sorted by constraint name.
