Thomas Dudziak commented on DDLUTILS-212:
-----------------------------------------
Your particular problem requires DdlUtils to understand functions and to be
able to read and recreate them across all databases that support them, which is
not a simple thing to implement.
One workaround would be to give DdlUtils the ability to execute arbitrary SQL
at a given step in the creation or alteration of a database (DDLUTILS-213).
For now, unfortunately you'll have to create the indexes manually (e.g. use the
sql task in Ant) as DdlUtils has no way of doing so.

> Affects Versions: 1.0
> Environment: RHEL 4 Linux
> Reporter: prasanna
> Assignee: Thomas Dudziak

> I created a postgres database and ran this SQL:
> /*create LANGUAGE plpgsql;*/
> CREATE OR REPLACE FUNCTION FUNC (/*id*/ INTEGER, /*status*/ INTEGER)
> RETURNS NUMERIC AS'
> BEGIN
> RETURN 0;
> END;
> 'LANGUAGE plpgsql IMMUTABLE;
> create table test_list
> (
> test_list_id integer not null, --pk
> test_id integer not null, --fk
> status_id integer not null --fk
> );
> create unique index uq_test_list on test_list(test_list_id, test_id,
> func(test_list_id, status_id));
> When trying to load the database schema in Jasper Server it fails with this
> exception:
> Caused by: org.apache.ddlutils.model.ModelException: The index uq_test_list
> in table test_list references the undefined column func(test_list_id,
> status_id)

> Still it fails with the same exception.
