# 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 | +-----------------+------------+---------------+ 9 rows in set (0.01 sec) obclient> drop tablegroup tpcc_group; ERROR 4615 (HY000): tablegroup is not empty obclient> ~~~
