How to use transformation script to add FK to relational model

Question

Hi,
I've looked through a few of the examples dealing with Foreign Key's, but I can't seem to get the code correct to add a new FK to a table and use the existing columns in the table.
This code will add a Foreign Key from ENVIRONMENT_REQUEST to the ENVIRONMENT table pointing to the columns in the ENVIRONMENT_PK index. The problem is that it also adds a new column in the ENVIRONMENT_REQUEST table to be used for the Foreign Key.
table = model.getTableSet().getByName("ENVIRONMENT_REQUEST");
remoteKey = model.getGlobalIndexSet().getByName("ENVIRONMENT_PK");
fk = table.addFK(model.getGlobalIndexSet().getByName("ENVIRONMENT_PK"));
fk.setName("NEW_FK_TO_ENVIRONMENT");
I have tried creating a localFKIndex but the generated column still exists. Is there an addFK method where I can specify the local columns to be used in the Foreign Key so the additional column is not created?

Answer 1

Guess the trick was to use table.addForeignKey passing as a parameter the referenced key and the list of columns in the local table
table = model.getTableSet().getByName("ENVIRONMENT_REQUEST");
remoteKey = model.getGlobalIndexSet().getByName("ENVIRONMENT_PK");
java.util.List<String> list = new ArrayList<String>();
list.add(table.getElementByName("ENVIRONMENT_ID"));
fk = table.addForeignKey(remoteKey, list);
fk.setName("NEW_FK_TO_ENV");
