Suppose on Contact record  wanted to check  if Name+ email+phone exists then display an error to the user that duplicate record.

 

Is there any sample code anyone can share with me?

You need to use a dynamic query and go through all of your records (contacts in this case)

Something similar to:

String where = '';
for (Contact cont: contacts)
{
  where += ' OR (Email = ' + cont.Email + ' AND Phone = ' + cont.Phone + ' AND Name = ' + cont.Name + ' AND Id != ' + cont.Id;
}
//This should give a general idea on how to build your WHERE part of the query you will need to do.
