Override doDML for custom type

Question

Hi,
I'm overriding the doDML method of my entity class. Instead of inserting directly into a certain table I redirect the insert handling to a special PL/SQL package method. This works fine, until I want to use a custom as one of the columns of the table / one of the arguments of the package method.
E.g. the custom type looks like this:
  CREATE OR REPLACE TYPE mylist AS TABLE OF VARCHAR2(10);I use this type for a nested table column in a certain table. The PL/SQL does some pre-/post-processing and inserts a new record in the table my entity object is based on. When I create the entity using the Entity wizard it correctly detects the column as of SQL type mylist and Java type oracle.jbo.domain.Array with elements of type String.
Anyway, the prepared statement I create looks something like the following:
  String stmt = "BEGIN mypkg.insert(:1, :2); END;";
  PreparedStatement p = e.getDBTransaction().createPreparedStatement(stmt, 2);
  if (getId() != null) p.setInt(1, getId().intValue());
  else p.setNull(1, Types.INTEGER);I want to set the 2nd parameter (which is of the mylist type) in a similar way. But I don't know which SQL type I should choose from. If I choose Types.ARRAY I get an invalid type error, the same goes for Types.OBJECT, and Types.BLOB. And which set... method should I call on the prepared statement? And what should I pass to this method? The Array object of the results of the getData() method of the Array object?
Regards,
Peter

Answer 1

Types.ARRAY should be the right sql-type
The value should be an oracle.sql.ARRAY instance.
To prepare and return one of this type you
first need to prepare the Array domain for DML by calling arrayDomain.prepareForDML(jdbcconn) (passing in the jdbc connection object) and then call arrayDomain.getData()to use in your setObject() call.
