MS-SQL's BULK INSERT could almost be compared to importing into
Firebird via external tables, with the exception that by default
MS-SQL's BULK INSERT ignores CHECK CONSTRAINTS and insert triggers.
But, those can be turned on as options of BULK INSERT.

So, essentially using Firebird's external table feature to import data
can be compared to using MS-SQL's BULK INSERT with the check
constraints(CHECK_CONSTRAINT) and use insert triggers(FIRE_TRIGGERS)
being specified.
