Hibernate set parameter null

1. 错误代码

 

session.createSQLQuery(
				"insert into teacherdev_basic_young(TEACHERID,FIRST_GRADU_DATE) values(:TEACHERID,:FIRST_GRADU_DATE)")
				.setParameter("TEACHERID", "2015")
				.setParameter("FIRST_GRADU_DATE", null).executeUpdate();

 

 报错： 

 

org.hibernate.exception.SQLGrammarException: could not execute native bulk manipulation query

 

 

2. 正确代码：

 

session.createSQLQuery(
				"insert into teacherdev_basic_young(TEACHERID,FIRST_GRADU_DATE) values(:TEACHERID,:FIRST_GRADU_DATE)")
				.setParameter("TEACHERID", "2015")
				.setParameter("FIRST_GRADU_DATE", null,Hibernate.TIMESTAMP).executeUpdate();
