我使用Django 1.6.2 + ORACLE 12 + cx_oracle 5.1.2甲骨文+ Django的+ bulk_create +長文本
這裏是我的模型
class Value(models.Model):
text= models.TextField()
我有一些文字，它的長度是在俄語3000個字符，當IM特林做到這一點：
text = 'some text' #3000 characters
v = Value(text=text)
v.save()
它的確定...
但是當我這樣做：
text = 'some text' #3000 characters
v = Value(text=text)
Value.objects.bulk_create([v])
我得到這個異常：
