mysql中如何修改表的名字?修改表名?
需求描述: 今天在进行mysql表的历史数据迁移,需要将某张表进行备份,修改表的名字,在此记录下操作过程.操作过程:mysql> create table ts01 like ti_o_sms; #创建表结构.这样的建表方式,不仅仅是表的结构,连带着索引也会同时创建.Query OK, 0 rows affected (0.02 sec)
mysql> alter table ts01 rename to ts01_new; #修改表名的语法:alter table rename to/as new_tablename;
Query OK, 0 rows affected (0.00 sec)
mysql> show tables;
+--------------------+
| Tables_in_mytest |
+--------------------+
| sms_send_blacklist |
| td_b_sendobject |
| ti_o_sms |
| ts01_new |
+--------------------+
rows in set (0.00 sec)
或者
mysql> alter table ts01_new rename AS ts02;
Query OK, 0 rows affected (0.03 sec)
mysql> show tables;
