##################################

查看ddl语句的日志，需要开启：

mysql> show global variables like '%innodb_print_ddl_logs%';
+-----------------------+-------+
| Variable_name         | Value |
+-----------------------+-------+
| innodb_print_ddl_logs | OFF   |
+-----------------------+-------+
1 row in set, 1 warning (0.19 sec)

mysql> set global innodb_print_ddl_logs=1;
Query OK, 0 rows affected (0.00 sec)

mysql> show global variables like '%log_error_verbosity%';
+---------------------+-------+
| Variable_name       | Value |
+---------------------+-------+
| log_error_verbosity | 2     |
+---------------------+-------+
1 row in set, 1 warning (0.00 sec)

mysql> set global log_error_verbosity=3;
Query OK, 0 rows affected (0.00 sec)

mysql>      

另外就是我们可以通过设置 ​

​innodb_print_ddl_logs=1​

​​ 和 ​

​log_error_verbosity=3​

​ 在 MySQL 的 系统日志里面查看 DDL log。
