Unsuccessful: alter table XXX drop constraint YYY in Hibernate/JPA/HSQLDB standalone

Question

I am trying to run some Hibernate/JPA examples using an in-memory HSQL DB. The error message I get is the following:

13:54:21,427 ERROR SchemaExport:425 - HH         


        

Answer 1

Just set dbCreate="update", and the errors go away immediately.
