MySQL バージョン 5.5.27
更新 2:これはかなり大きいと確信しており、同じ動作でゼロからテストを行いました。MySQL サイトのバグを開き、結果を更新します。
更新: ストアド プロシージャの一時テーブルから列を削除すると、正常に動作します。この問題は、列を手で落とした場合にのみ発生します。
次の行はストアド プロシージャで失敗し、エラーが発生します。
mysql> insert into player_record_week select * from pr_temp;
mysql> call insert_agg_week('2013-02-26');
ERROR 1054 (42S22): Unknown column 'prod_gamestats.pr_temp.total_battles' in 'field list'
手で実行すると動作します。
mysql> insert into player_record_week select * from pr_temp;
Query OK, 211708 rows affected (2.23 sec)
Records: 211708 Duplicates: 0 Warnings: 0
一時テーブルに total_battles 列を残すと、列数の不一致に関するエラーで失敗します。テーブル pr_temp は、player_record_week テーブルを複製することによって作成されます。
| insert_agg_week | | CREATE PROCEDURE `insert_agg_week`(insert_week date)
begin
delete from player_record_week where stat_week = insert_week;
delete from player_tank_record_week where stat_week = insert_week;
delete from player_ratings_week_agg where stat_week = insert_week;
delete from player_ratings_week_per where stat_week = insert_week;
delete from global_week where stat_week = insert_week;
delete from global_tank_week where stat_week = insert_week;
insert into player_record_week select * from pr_temp;
insert into player_tank_record_week select * from ptr_temp;
insert into player_ratings_week_agg select * from pratings_temp_agg;
insert into player_ratings_week_per select * from pratings_temp_per;
insert into global_week select * from global_week_temp;
insert into global_tank_week select * from global_tank_week_temp;
end | utf8 | utf8_general_ci | latin1_swedish_ci |
余分な列を保持すると、ストアド プロシージャは列数の不一致でエラーになります。
余分な列を削除すると、削除した列への参照でストアド プロシージャがエラーになります。
mysql> call insert_agg_week('2013-02-26');
ERROR 1054 (42S22): Unknown column 'prod_gamestats.pr_temp.total_battles' in 'field list'
コマンドを手動で実行すると、問題なく実行されます。
