Question

I have a criteria query not really working. Here the model:

@Entity
public class Flaw extends BaseEntity implements Serializable {
    ...
    @Lob
    @Basic(fetch=FetchType.LAZY)
    private String text;
    ...

This query is going to be executed by hibernate (from Logs):

Hibernate: 
    select
        ...
        flaw0_.text as col_7_0_,
        ...
    from
        Flaw flaw0_,
    where
        ...
        and (
            flaw0_.text like ?
        ) 
    order by
        flaw0_.text desc

But then I get the following StackTrace:

3171 [main] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 0, SQLState: 42883
3171 [main] ERROR org.hibernate.util.JDBCExceptionReporter - ERROR: operator does not exist: text ~~ bigint
3198 [main] INFO org.hibernate.impl.SessionFactoryImpl - closing

With oder properties it works fine, just with the like operator on the CLOB it is not working. Is this a Hibernate or Postgres problem? Or is this type of query not possible on CLOBs?

I am using:

• Hibernate 3.6.3
• PostgreSQL 8.4.8
• PostgreSQL 8.3 JDBC3 with SSL (build 603)

Any Ideas?

Update:
I did some further investigation:

• The above annotation creates correctly a text postgres type
• If I run the sql query , that hibernate prints out, it works.

After trying around I found the following solution which worked for me. I had to add the following annotation, and now it works:

@Type(type = "org.hibernate.type.TextType")
