When editing rows in a table, the UI setting (checkbox):
Tools->Options->SQL Generation->Ignore Autoincrement columns for Insert
allows bypass of some dbms auto-maintained columns from Insert statements.
DB2 supports additional auto-maintained columns options, eg:
GENERATED ALWAYS AS TRANSACTION START ID
which auto maintains a timestamp of the row's last update.
Please add coverage of this sql syntax to the Ignore for Insert checkbox ,
so that the table editor can also Insert rows into tables with such columns.
