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 |
+--------------------+
4 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;+--------------------+| Tables_in_mytest |+--------------------+| sms_send_blacklist || td_b_sendobject || ti_o_sms || ts02 |+--------------------+4 rows in set (0.00 sec
备注:表名已经成功的进行修改.
官方文档修改表名的语法:
mysql> help alter table
Name: 'ALTER TABLE'
Description:
Syntax:
ALTER TABLE tbl_name
[alter_specification [, alter_specification] ...]
[partition_options]
alter_specification:
table_options
.......| RENAME [TO|AS] new_tbl_name
.......
