Hi experts,<br />
<br />
If I have two decimal columns in a table and I want to return the sum of the two columns added together as another column in my resultset, how do I do it when one of the columns 'may' be NULL?<br />
<br />
(OPR.refund_product_value + OPR.refund_extra_value) AS refund_total_value<br />
<br />
If one of the two values here is NULL, the result is also NULL. <br />
<br />
Help appreciated.
