Changing double to Double in hybris

Question

I have a requirement to change a field from double to Double in hybris typeSystem and was wondering if it actually creates a new database field or just changes the type in app layer. Thanks in advance.

Answer 1

After the items.xml change and system update the data base field remained the same type. All reads and write are from the same column. So, the answer to my question is no, the column type does not change in database. Only the application layer (model) has changed the field from double to Double.
