How to remove DEFAULT keyword for IDENTITY column from auto generated insert script in DB2 database?

Issue

• We're using a DB2 LINUX (10.5 FP5) DB federation server and created nicknames that are in fact Synonyms to MS SQL 2012 Tables. All this is working correctly (SELECT, INSERT, UPDATE, DELETE, etc.).

• In Java applications, developers are using DB2Dialect.

• The problem we have is related to the INSERT statements currently generated by Hibernate.

• Is it possible to remove an IDENTITY COLUMN of default keyword from the INSERT statements ?

• The SQL statement generated by Hibernate is :

2015-04-13 13:30:48,015 INFO [STDOUT] Hibernate: insert into MY_TABLE (ID, FIELD_ONE, FIELD_TWO) values (default, ?, ?)
2015-04-13 13:30:48,040 WARN [org.hibernate.util.JDBCExceptionReporter] SQL Error: -30090, SQLState: 25000

• This kind of statement will work with DB2 Table but not with a DB2 Nickname pointing to a MS SQL Table.
