DTYPE": invalid identifier

Upgraded hibernate from 4.2.11 to 5.2.11 and done Single Table Inheritance into the Hibernate, but I am getting an error like ORA-00904: “XXXXXXX”. “DTYPE”: invalid identifier

Sorry, but we need more information to help you here. The full stack trace and full error message would be a good start. Did you check if the column DTYPE exists in the table of question?
