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.
