当我尝试保存实例时，我收到了这个奇怪的错误：
WARN [15:06:27,917] JDBCExceptionReporter - SQL Error: 20000, SQLState: 42X04
ERROR[15:06:27,917] JDBCExceptionReporter - Column 'ad0b8d24-f596-47cb-9d79-06a3c9c1de26' is either not in any table in the FROM list or appears within a join specification and is outside the scope of the join specification or appears in a HAVING clause and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE statement then 'ad0b8d24-f596-47cb-9d79-06a3c9c1de26' is not a column in the target table.
行未插入数据库。 看起来它正在尝试使用scenario_id（uuid）作为列名。但为什么呢？
我正在使用此数据访问对象：
public interface ScenarioDao extends GenericDao<Scenario, String> {
public List<Scenario> getScenariosWhereOwner(Person owner);
public List<Scenario> getScenariosWhereOwner(Person person, int LIMIT);
...
}
public interface GenericDao <T, PK extends Serializable>{
public PK create(T newInstance) {
PK primaryKey = (PK) getHibernateTemplate().save(newInstance);
return primaryKey;
}
}

我尝试使用以下代码创建它：
scenario = new Scenario();
scenario.setPrivateScenario(some boolean);
scenario.setScenarioLength(some int);
scenario.setDescription(some string);
scenario.setTitle(some string);
scenario.setResearchGroup(some ResearchGroup);
scenario.setPerson(some Person);
正确设置所有这些参数。我也使用GenericDao与其他对象没有错误。这是由hibernate生成的insert语句：

当我尝试执行时：

session.createSQLQuery(query).executeUpdate();
我得到同样的错误。
当我尝试直接执行查询时，我得到一个非常奇怪的错误：

答案 0 :(得分：0)
我忘记在触发器表中设置capture_big_lobs。将值更改为1解决了问题。但是，如果列为NULL，则SymmetricDS将抛出Null Pointer Exception。我使用的是3.5.10，所以也许它在新版本中得到了解决。
