Making the User Object standard field Unique.

Hi all,

 

I have a situation where, the Standard Field 'Extension' of User Object needs to be Unique.

 

Is there any way I can make this field unique.

 

Any help regarding this would be highly appreciated.

 

Thanks in Advance,

Mohammed Uzair.

Your trigger should like this :

 

trigger ExtesionTrigger on User (before insert , before update)
{
    Set<String> setExtension = new Set<String>();
    for(User u : trigger.new)
        {
            
            Boolean isNewExt = setExtension.add(u.Extension);
            //This will ensure that in bulk insert you are not inserting two users with same extension
            if(!isNewExt)
                u.addError('Dulicate Extension');
        }
        
    List<User> ul = [Select id from User where Extension in: setExtension];
    
    if(ul.size() > 0)
        {
            trigger.new.get(0).addError('Dulicate Extension');
        }
    

}

 I hope this will help you.

I think we cannot make a standard field unique.

 

There is one alternative solution. Create a custom field on User, make that unique. Write a trigger on User to update that field with Extension. If there is a duplicate value in Extension, trigger will try to copy it to your custom field and will throw error.

Hi

I used Trigger for Making the field Unique

 

see the below code

 

trigger ExtesionTrigger on User (before insert)
{
list <User> u1 = new List <User>();
u1 = [select Extension from User];
if(Trigger.isInsert)   
{
For(integer i=0;i<u1.size();i++)
{
for(User u2 : Trigger.New)
{
if(u1[i].Extension == u2.Extension)
{
u2.Extension.addError('Trigger Error::This value already Exist');
}
}
}
}
}

 

I think it will be usefull for you

 

Thanks!

}
