How to edit an existing and working Schema in MySQL Workbench?

Is it possible to continue or extend an existing schema with MySQL Workbench? This is the scenery: 1) We design our DB in MySQL Workbench 2) We export it as SQL file and execute it in our MySQL Server 3) We insert a lot of开发者_开发百科 data and use our DB 4) We want to add more tables, fields, or anything to our Schema

The 4 step is my dude, can we edit our scheme in MySQL Workbench if our DB is working and with data?

yes, you can sync your database with workbench model. the sync works both ways so you can update the model from the database, or update the database from the model.

Use file->import and select an sql file, which you can export via phpMyAdmin.
