删除表组

如果要删除表组，得先确认表组中没有表。具体方法就是从表组中删除表，或者将相关表的表组属性清空。

示例如下：

obclient> show tablegroups;
+-----------------+------------+---------------+
| Tablegroup_name | Table_name | Database_name |
+-----------------+------------+---------------+
| oceanbase       | NULL       | NULL          |
| tpcc_group      | cust       | tpccdb        |
| tpcc_group      | dist       | tpccdb        |
| tpcc_group      | hist       | tpccdb        |
| tpcc_group      | nord       | tpccdb        |
| tpcc_group      | ordl       | tpccdb        |
| tpcc_group      | ordr       | tpccdb        |
| tpcc_group      | stok       | tpccdb        |
| tpcc_group      | ware       | tpccdb        |
+-----------------+------------+---------------+
