説明

TabSeparated フォーマットに似ていますが、値を name=value 形式で出力します。 名前は TabSeparated フォーマットと同じ方法でエスケープされ、= 記号も同様にエスケープされます。

Query
SELECT * FROM t_null FORMAT TSKV
Response
x=1    y=\N
小さいカラムが大量にある場合、このフォーマットは非効率であり、通常これを使用する理由はありません。 それでも、効率の点では JSONEachRow フォーマットに劣りません。
パース時には、異なるカラムの値の順序は任意です。 一部の値は省略しても問題なく、その場合はデフォルト値と同じものとして扱われます。 この場合、ゼロおよび空の行がデフォルト値として使用されます。 テーブルで指定できるような複雑な値は、デフォルト値としてサポートされていません。 パースでは、等号や値を伴わない追加フィールド tskv を含めることもできます。このフィールドは無視されます。 インポート時には、未知の名前のカラムはスキップされます。 これは、setting input_format_skip_unknown_fields が 1 に設定されている場合です。 NULL は \N としてフォーマットされます。
