Teradata requires that "create index" specify the column names after the index name.
e,g.
H2: create index ind1 on tablename(indexColumn)
Teradata: create index ind1(indexColumn) on tableName

With the existing code, I see the following error when trying to create an index:
[Teradata Database] [TeraJDBC 14.10.00.39] [Error 3706] [SQLState 42000] Syntax error:
Must specify index field(s) for CREATE INDEX.
