mysqlエラー：ERROR 1241（21000）：オペランドに1列が含まれている必要があります

Question

私はmysqlクエリの問題に直面しています。あるテーブルから別のテーブルにデータをコピーする必要があります。私はこれを実行するには、以下のエラーを取得しています、

mysql> insert into voucher (code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at) select (code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at) from voucher_log ;

：しかし、私は使用していたクエリがある

ERROR 1241 (21000): Operand should contain 1 column(s)

Answer 1

insert into voucher (code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at) select (code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at) from voucher_log ;

はあなたのクエリがあるべき

insert into voucher (code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at) select code, amount, expire_at, state, driver_id, asset_account_id, created_at, updated_at, creator_id, agent, voucher_batch_id, image, city_id, country_id, serial_number, updater_id, redeemed_at from voucher_log ;

選択クエリに()を入れています。その部分は間違っています。
