org.hsqldb.HsqlException: data exception: string data, right truncation

This exception appear when you try to populate a database with DBUNIT, and there is one text field which content bigger than the column size. (I spent almost 30 minutes until I realized it...)

The solution is to increase the column size in the entity mapping.

As you can see, I had a column named T_EXPED with length 2, and I tried to put in it a string with lenght 3.

Entity mapping:

@Entity
@Table(name="INDDO")
public class Inddo {
 (...)
 
 @Column(name="T_EXPED", columnDefinition="char(2)")
 private String tipoExpediente;
 
 (...)
}

DBUNIT file:

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
 <INDDO (...) T_EXPED="22I" (...) />
</dataset>
