MySQL 版本 5.5.27
UPDATE2：很确定这是一个大问题，从头开始进行了相同行为的测试。在 MySQL 站点上打开错误并将更新结果。
更新：如果我从存储过程中的临时表中删除列，它工作正常。仅当我手动删除列时才会出现问题。
以下行在存储过程中失败，并出现错误：
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'
如果我手动运行它，它可以工作。
mysql> insert into player_record_week select * from pr_temp;
Query OK, 211708 rows affected (2.23 sec)
Records: 211708 Duplicates: 0 Warnings: 0
如果我将 total_battles 列保留在临时表中，则会失败，并出现有关列计数不匹配的错误。表 pr_temp 是通过复制 player_record_week 表创建的。
| 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 |
如果我保留额外的列，则存储过程将因列数不匹配而出错。
如果我删除额外的列，存储过程会因引用我删除的列而出错：
mysql> call insert_agg_week('2013-02-26');
ERROR 1054 (42S22): Unknown column 'prod_gamestats.pr_temp.total_battles' in 'field list'
如果我手动运行命令，它运行没有问题：
