I need to fish out the person's name from a list but I only want the name of the person that occurs once in the list - minus those names that occurs more than once. Now, I know about "distinct" and "unique", but this is not what I want. All I want is to be able to fish out the names of the people who have only one and exactly only one entry in the list. I do not want the names of those people who have more than one entry in the list. Could one of you do me a huge favor give me some hints as to how to contruct the select statement for this.
