oracle迁移到mysql--mysql拼接脚本重命名表名

oracle迁移到mysql–mysql重命名表名的拼接脚本

由于mysql8.0一开始建成对大小写敏感，所以目前打算统一为小写，而之前配置了ogg默认*号匹配的是大写，所以考虑先将表名都改成大写后同步，等同步完成后再改回小写表名：

由于涉及表多，所以通过拼接的方式生成重命名表名的语句，

mysql> select CONCAT('alter table ',table_name,' rename to ',upper(table_name),';') from information_schema.tables where table_schema='resdb';
+------------------------------------------------------------------------------------+
| CONCAT('alter table ',table_name,' rename to ',upper(table_name),';')              |
+------------------------------------------------------------------------------------+
| alter table ADDRESSINFO rename to ADDRESSINFO;                                     |
| alter table ADDR_SEGM rename to ADDR_SEGM;                                         |
| alter table AN_COMBINER rename to AN_COMBINER;                                     |
| alter table AN_COMBINER_CONN rename to AN_COMBINER_CONN;                           |
| alter table AN_COMBINER_PORT rename to AN_COMBINER_PORT;                           |
| alter table AN_LAN_IPTV_PORT rename to AN_LAN_IPTV_PORT;                           |
| alter table AN_LOGIC_CONN rename to AN_LOGIC_CONN;                                 |
| alter table AN_NE_DEVICE rename to AN_NE_DEVICE;                                   |
| alter table AN_ODN rename to AN_ODN;                                               |
| alter table AN_ODN_CARD rename to AN_ODN_CARD;                                     |
| alter table AN_ODN_FINISHRENOVATE_STATUS rename to AN_ODN_FINISHRENOVATE_STATUS;   |

检查ogg是否同步完成：

同步完成后修改表名为小写，可以让开发人员测试了。

mysql> select CONCAT('alter table ',table_name,' rename to ',lower(table_name),';') from information_schema.tables where table_schema='resdb';
+------------------------------------------------------------------------------------+
| CONCAT('alter table ',table_name,' rename to ',lower(table_name),';')              |
+------------------------------------------------------------------------------------+
| alter table ADDRESSINFO rename to addressinfo;                                     |
| alter table ADDR_SEGM rename to addr_segm;                                         |
| alter table AN_COMBINER rename to an_combiner;                                     |
| alter table AN_COMBINER_CONN rename to an_combiner_conn;                           |
| alter table AN_COMBINER_PORT rename to an_combiner_port;                           |
| alter table AN_LAN_IPTV_PORT rename to an_lan_iptv_port;                           |
| alter table AN_LOGIC_CONN rename to an_logic_conn;                                 |
| alter table AN_NE_DEVICE rename to an_ne_device;                                   |
| alter table AN_ODN rename to an_odn;                                               |
| alter table AN_ODN_CARD rename to an_odn_card;                                     |
| alter table AN_ODN_FINISHRENOVATE_STATUS rename to an_odn_finishrenovate_status;   |
| alter table AN_ODN_PICTURE rename to an_odn_picture;                               |
| alter table AN_OLT rename to an_olt;                                               |

非交互式输出到rename_tab.sql中，方便操作：

mysql -ugistar -pxxxx -h192.168.207.143 -A -D resdb -e "select CONCAT('alter table ',table_name,' rename to ',lower(table_name),';') from information_schema.tables where table_schema='resdb';" > /root/rename_tab.sql

然后执行重命名操作：

[root@lnpg ~]# mysql -ugistar -p1qazXSW@ -h192.168.207.143 -A -D resdb < /root/rename_tab.sql
mysql: [Warning] Using a password on the command line interface can be insecure.

核查结果满足预期小写表：
