New description:

 I have to 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?
