mysql: import schema without losing data

Question

I have a database of about 15 tables which I restructured a bit (changed to innoDB, created Foreign Keys etc) using MySQL Workbench. I can extract the schema in sql format from the EER diagram but how can I import it in mySQL without losing my data?

Thanks in advance

Answer 1

mysql -uuser -ppassword dbname < schema.sql

但是不要忘记创建数据库dbname以及为用户user授予user 。
