Hi <br />
Is there a way for me to return me to find duplicate unique identifiers in a table. <br />
<br />
So for example say we have the the following fields in a table i.e. ID, ClientID, Name<br />
<br />
Lets say ClientId is a unqiueIdentifer and i want to return all clientids which are contained in the table more than once?<br />
<br />
Thanks<br />
