Interface DataColumnConstraint

Represents a row in the gpkg_data_column_constraints table.

Constraints can be of type 'enum', 'range', or 'glob' and define valid values or value ranges for data columns.

interface DataColumnConstraint {
    constraint_name: string;
    constraint_type: string;
    description: string | null;
    max: number | null;
    max_is_inclusive: boolean | null;
    min: number | null;
    min_is_inclusive: boolean | null;
    value: string | null;
}
