 2. 导出PostgreSQL表结构

$ pg_dump --verbose --schema-only --table=noco_il_16q1.result_basic region_il -f /usr/local/pgsql/dba/exp/result_basic_schema.sql

 3. 导出PostgreSQL表的所有字段

region_il=# COPY result_basic TO ‘/usr/local/pgsql/dba/exp/result_basic.csv‘ WITH (DELIMITER ‘^‘,FORMAT csv,FORCE_QUOTE *);
COPY 2611527

 

 4. 将备份集传到MySQL数据库服务器

$ scp /usr/local/pgsql/dba/exp/result_basic* root@172.16.101.66:/usr/local/mysql/dba/imp/

 

5. 编辑表结构文件修改字段类型并创建MySQl表结构

region_il>source /usr/local/mysql/dba/imp/result_basic_schema.sql;
region_il>desc result_basic;
