Firebird: Adding Index in Create Table Statement

I've serach the many websites about firebird, but couldn't find an answer to my question.

I'm using ado .net for creating a table in firebird. And I want to create an index for one of the fields while creating the table:

Fbsql = "CREATE TABLE TEST( " +
        "TEST_ID Integer NOT NULL, " +
        "DESCRIPTION Varchar(15), " +
        "PRIMARY KEY (TEST_ID) " + 
        "USING DESCENDING INDEX IDX_DESC ON TEST (DESCRIPTION)); ";

But this code doesn't work, I get an "Token unknown" error on the word "on". What would be the right way to do this if possible?

No, this doesn't work. If you want to create an index, you need to do that in a separate create index statement.

The only indexes that can be created in a create table are those created automatically for primary, unique and foreign keys.

The using-clause in your question is to control the creation of the index (mainly name) backing one of those keys. It can't be used to create additional indexes.
