I’m playing around with JPA using MyEclipse and was wondering what selecting “Enable dynamic DB table creation” on the Add JPA Capabilities dialog does? I searched around and can’t find any information on this.
This tells the underlying persistence API that if it cannot find the tables it wants for the entities, it will create them on-the-fly.
If you are working with an existing database, you do NOT want that enabled. If you are working on a brand new project or running test cases against in-memory DBs, it can be a very handy thing to use.
