Thank you very much :slight_smile:

Hi there, is there a specific date for this feature release?

Kind Regards,

Hi @skuang and @Art_Rodriguez, sorry for the long wait. We’ve actually just released this feature. Example code:

Table orders {
  id int [primary key]
  user_id int [not null]
  status varchar
  created_at varchar [null]

Let me know if this works for you?

null does not work with mysql timestamp

Hi @Edilson_Silva, thank you for your feedback. I’m Khoa from dbdiagram team, can you explain more about the problem you are having so that we can support you better?
