If you are only using a single schema in your database, you could create an empty database with all your tables that
youthen use as the template database when creating a new one:
 

Then each time you want to reset your schema (=database) you do a

drop database real_database;
create database real_database template template_database;

Then you don't need to adjust your "reset" script if your database changes (you only maintain the template database
usingyour SQL scripts)
