Oracle 数据库通过exp/imp工具迁移指定数据表

article 2025/3/30 4:30:07

项目需求：从prod数据库迁移和复制2个表(BANK_STATE，HBS)的数据到uat数据库环境。

数据库版本：Oracle Database 19c Enterprise Edition Release 19.0.0.0.0

迁移工具：客户端exp/imp工具

-- 执行命令 从Prod数据库导出数据

exp username/password@server_ip:1521/service_name TABLES=(BANK_STATE,HBS) file=C:\oracle\dump\cola_tables_20250324.dmp log=C:\oracle\dump\cola_tables_20250324_exp.log

-- Login DB  进入sqlplus

sqlplus username/password@server_ip:1521/service_name


-- 提前在UAT环境删掉已经存在的表

DROP TABLE BANK_STATE;
DROP TABLE HBS;

-- 执行命令 将dump文件导入到uat数据库

  imp username/password@server_ip:1521/service_name file=C:\oracle\dump\cola_tables_20250324.dmp log=C:\oracle\dump\cola_tables_20250325_imp.log tables=(BANK_STATE,HBS)
