如果它们是同步的,如何查看本地数据库对服务器数据库的更改? 以及如何不时同步它们? 没有第三方工具

A continuation to Sync large local DB with server DB (MySQL), how can we see the differences between a local DB and server DB, before we go for syncing them?

I dont want to use any third party tools.

Have a look at Schema and Data comparison/synchronization tools in dbForge Studio for MySQL. There are also separate tools for data and schema comparison.
