mysql performance_schema缺失表

Question

在sudo apt-get install安装的ubuntu上使用MySQL5.6.19，我丢失了几个表(在尝试使用性能报告时从Workbench收到了警报)。

以下是我在performance_schema中拥有的表：

+----------------------------------------------+
| Tables_in_performance_schema                 |
+----------------------------------------------+
| cond_instances                               |
| events_waits_current                         |
| events_waits_history                         |
| events_waits_history_long                    |
| events_waits_summary_by_instance             |
| events_waits_summary_by_thread_by_event_name |
| events_waits_summary_global_by_event_name    |
| file_instances                               |
| file_summary_by_event_name                   |
| file_summary_by_instance                     |
| mutex_instances                              |
| performance_timers                           |
| rwlock_instances                             |
| session_connect_attrs                        |
| setup_consumers                              |
| setup_instruments                            |
| setup_timers                                 |
| threads                                      |
+----------------------------------------------+

通过检查医生们，我发现我遗漏了以下表格：

• performance_schema.events_statements_current
• performance_schema.events_statements_history
• performance_schema.events_statements_history_long
• performance_schema.events_stages_current
• performance_schema.events_stages_history
• performance_schema.events_stages_history_long

这是显示引擎的输出：

mysql> show engines;
...
*************************** 8. row ***************************
      Engine: PERFORMANCE_SCHEMA
     Support: YES
     Comment: Performance Schema
Transactions: NO
          XA: NO
  Savepoints: NO
...

请有人张贴show create table语句，这样我就可以创建它们了吗？如果你注意到另一张我错过的表，我也会非常感激你为之制作的表。

您拥有的表来自MySQL 5.5，缺少5.6中的新表。

请运行mysql_upgrade。
