There has been no real demand for this and it is easily handled as a user type. So lets not bloat Hibernate.

Description:
SqlData type
We have some Oracle objects and need to read/write its
to database. We have java classes that implements
java.sql.SqlData interface but Hibernate can't map SQL
object types to java (perhaps I simple don't know how to
do it). I wrote SqlDataType class which can do it for me
and changed TypeFactory for produces SqlDataType for
classes which instantiate SqlData interface. All work
nice but I can't use fields of that classes in Query. It will
be nice to see it in future release.
Here is my implementation of SqlDataType:
--------------------------------
package net.sf.hibernate.type;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
public class SqlDataType extends PrimitiveType {
protected Class persistentClass;
public SqlDataType(Class persistentClass) {
this.persistentClass =
persistentClass;
}
public Object get(ResultSet rs, String name)
throws SQLException {
return rs.getObject(name);
}
public Class primitiveClass() {
return persistentClass;
}
public Class getReturnedClass() {
return persistentClass;
}
public void set(PreparedStatement st, Object
value, int index)
throws SQLException {
if (value == null) st.setNull(index,
sqlType());
else st.setObject(index, value);
}
public int sqlType() {
return Types.JAVA_OBJECT;
}
public String getName() { return
persistentClass.getName(); }
public String objectToSQLString(Object
value) throws Exception {
return value.toString();
}
}
------------
Here changes in hueristicType method of TypeFactory
class
else if (
SQLData.class.isAssignableFrom(typeClass) ) {
type = new SqlDataType(typeClass);
}
With best regards.
