Question

I am using hibernate to fetch rows from the table.

List<Work> W= sessionFactory.getCurrentSession().createSQLQuery("Select * from T_WORK ").addEntity(Work.class).list();

This query works fine.

But the below query is not working fine.

List<Work> W= sessionFactory.getCurrentSession().createSQLQuery("Select * from T_WORK WHERE STATUS = 5 ").addEntity(Work.class).list();

I am getting a error as .

could not execute query

I am using Oracle and status column is of the number datatype.

In the workitem class

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "STATUS_CODE", nullable = false)  
private Status status;

Where am i wrong?
Thanks in advance.

How i can achieve this?

Answer 1

You are using native SQL query. That means, you should use SQL names of your fields. So use STATUS_CODE instead of STATUS.

i.e. ...createSQLQuery("Select * from T_WORK WHERE STATUS_CODE = 5 ")...
