Question

I have an application that is connected to an SQL database using Hibernate. When removing a person from a particular part of the application I want to reset all the information that had been set in the particular part. Below is an example of what I am on about

Stage: Bank

Fields to be set in stage:
BankName
AccNo
IBANNo
...

When removing a Person from this stage, what is the best way to reset all the information

public void resetInfo(Person person){
    person.setBankName(null);
    person.setAccNo(null);
    person.setIBANNo(null;)
}

or

public void resetInfo(Person person){
    if(person.getBankName != null)  {  
        person.setBankName(null);
    }
    if(person.getAccNo != null)  {  
        person.setAccNo(null);
    }
    if(person.getIBANNo != null)  {  
        person.setIBANNo(null;)
    }
}

or is there a better way to do this?

Answer 1

public void resetInfo(Person person) {     
    person.setBankName(null);     
    person.setAccNo(null);     
    person.setIBANNo(null;) 
} 

This is fine, as Hiberante internally keeps track of which all field values are changed to specify that in update query.

Also you can check this by setting show_sql = true, to check what update query is generated by Hibernate.
