MySQL to ADB PG Converter

使用步骤

  1. 使用mysqldump dump出PG兼容的MySQL建表语句(修改下面语句中的databasename和dumpfile.sql),此处dump语句很重要,一定要转为PG兼容的建表语句:

    mysqldump --opt --compatible=postgresql --default-character-set=utf8 -d databasename -r dumpfile.sql -u username -p

  2. 执行转换脚本,dumpfile.sql和adbforpg.sql填写真实的值

    python db_converter.py dumpfile.sql adbforpg.sql

adbforpg.sql是转换后的ADB for PG的建表语句,如果需要有需改需求,可以直接在文件中进行修改。重点要关注一下分布列的选择,默认选择MySQL表中的主键作为分布列,如果MySQL表结构中无主键,请手动修改选择分布列。
