檢視是否支援分割槽：

mysql> show variables like '%partition%';
+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| have_partitioning | YES   |
+-------------------+-------+
1 row in set (0.00 sec)

可以查看錶是否為分割槽表

show table status like 'table_name';

例如：

mysql> show table status like '%terminal_alarm_list_bak%'\G;

如果要檢視分割槽的資訊，可以通過sql語句來查詢：

 select * from information_schema.partitions where table_schema=schema() and table_name = '表名';

mysql> select * from information_schema.partitions where table_schema=schema() and table_name = 'terminal_alarm_list_bak'\G;
