Seems you missed the point
My mapping was like this, to a String-property
@Column(name="my_name")
@Lob
@Type(type="org.hibernate.type.StringClobType")
private String someLongDescription;
But I have to use @Lob in order to be able to persist this long String
in Oracle. With PG it works without the @Lob but then it's not portable.
The problem is that Hibernate uses ResultSet.setClob() regardless of the
DB-dialect when it sees @Lob on a String-type. This shouldn't be a
problem is the PG JDBC-driver implemented setClob as setString, but some
think that's not correct.
