# 辞書 {#dictionaries}
|
|
|
|
辞書はマッピングです (`key -> attributes`）それはさまざまなタイプの参照リストのために便利です。
|
|
|
|
ClickHouseは、クエリで使用できる辞書を操作するための特別な関数をサポートしています。 関数で辞書を使用する方が簡単で効率的です。 `JOIN` 参照のテーブルを使って。
|
|
|
|
[NULL](../../sql-reference/syntax.md#null-literal) 値を辞書に格納することはできません。
|
|
|
|
ClickHouseサポート:
|
|
|
|
- [組み込み辞書](internal-dicts.md#internal_dicts) 特定の [関数のセット](../../sql-reference/functions/ym-dict-functions.md).
|
|
- [プラグイン(外部)辞書](external-dictionaries/external-dicts.md#dicts-external-dicts) と [関数のセット](../../sql-reference/functions/ext-dict-functions.md).
