New description:

 I have two models:
 {{{
 class Record(models.Model):
 hash = models.CharField(max_length=32)
 source = models.ForeignKey(Source, on_delete=models.CASCADE)
 create_date = models.DateTimeField(db_index=True)
 update_date = models.DateTimeField(db_index=True)
 deleted = models.BooleanField(default=False, db_index=True)


 class RecordContent(models.Model):
 record = models.OneToOneField(Record, primary_key=True,
 on_delete=models.CASCADE)
 content = models.TextField(max_length=100 * 1024)
 }}}
 In MySQL this function works fine:
 {{{
 def _create_records(record_containers):
 records = []
 record_contents = []
 for record_container in record_containers:
 records.append(record_container['record'])
 record_contents.append(record_container['content'])

 models.Record.objects.bulk_create(records)
 models.RecordContent.objects.bulk_create(record_contents) # in Oracle
 ORA-01790: expression must have same datatype as corresponding expression
 }}}
 But in Oracle this code thows exception: ORA-01790: expression must have
 same datatype as corresponding expression

 If refactor the function _create_records:
 {{{
 def _create_records(record_containers):
 for record_container in record_containers:
 models.Record.objects.bulk_create([record_container['record']])
 models.RecordContent.objects.bulk_create([record_container['content']])
 }}}
 there is no exception is thrown.

 What happens?

Comment:

 What version of Django are you using? It might be a duplicate of #22669
 (fixed in Django 2.0). If not, please try to minimize the code to
 reproduce the issue, including the data that causes the crash.
