SQL: Exception: I found that the org.hibernate.OracleDialect always was set to default Dialect. If I change org.hibernate.OracleDialect to org.hibernate.MariaDBDialect, it works. I think there is a bug in org.hibernate.OracleDialect, but I can’t change it to older OracleDialect like Oracle10gDialect due to the reason in below alert Also I try all the hibernate 6.x version, neither works.
