fdlzp commented on issue #2138: Could not commit JPA transaction when I use save to insert data to oracledatabase URL: https://github.com/apache/incubator-shardingsphere/issues/2138#issuecomment-478350401 It is likely that the primary key causes this problem. If you don't set the primary key to increase by itself，I can insert data. But I need the primary key to increase by itself (by uuid). I don't know how to deal with it.
