<div class="content wysiwyg-content">
I have been doing some work De-Duplicating contacts using the Difference function in SQL server 2000 and have come across on odd result. You receive a different return value depending on the order in which you supply the parameters e.g<br />
<br />
Difference('A','Andy') = 3<br />
Difference('Andy','A') = 2<br />
<br />
Does anyone know why this is?
