If i am adding a new column to existing table, how do i migrate existing values? Okie. I have a table called User with columns First_Name, Last_name, email. And in some point i am adding a new column say DoB. When i query the existing values, i am getting exception like entity DoB is not present. So i need to go back and delete all the existing data available and then recreate java file. Is there any workaround atleast in local env.
