it's incorrect to zero out table->triggers->extra_null_bitmap before a statement, because if insert uses an explicit field list and omits a field that has no default value, the field should get NULL implicitly. So extra_null_bitmap should have 1s for all fields that have no defaults * create extra_null_bitmap_init and initialize it as above * copy extra_null_bitmap_init to extra_null_bitmap for inserts * still zero out extra_null_bitmap for updates/deletes where all fields definitely have a value * make not_null_fields_have_null_values() to send ER_NO_DEFAULT_FOR_FIELD for fields with no default and no value, otherwise creation of a trigger with an empty body would change the error message
