Native SQL throwing Invalid Column Name Exception

Question

I am using Hibernate 3.2.5 for my application.

I have a Dept table and an Employees table.

Dept.java

Answer 1

I had the same issue.

The reason is my column name in annotation is not correct.

@Column(name = "CUSTOMER_NAME", length = 200)

should be changed to

@Column(name = "CUST_NM", length = 200)

Answer 2

you have this in your mapping:

<column name="DEPT_NAME"></column>

but there is no such column in your sql between Select and from:

session.createSQLQuery("Select d.DEPT_ID, e.EMP_NAME from Dept d,Emp e where d.DEPT_ID = e.DEPT_ID")

Hibernate has no possibilitys to bind the attribute. Try it with this:

session.createSQLQuery("Select d.DEPT_ID, d.DEPT_NAME, e.EMP_NAME from Dept d,Emp e where d.DEPT_ID = e.DEPT_ID")

Answer 3

Here are my 2cents in addition to what Stefan Beike.

In your case, the table is small. But if you are writing a similar query for a large table, and if you don't want the entire columns to be fetched into the memory, writing a new DataTransferObject to use as your resultset-ref would be ideal.
