Can anyone give me some helpful advice in regards to this SQL programming problem in the screenshot below? I tried this and a UNION operator to no avail. I'm suppose to list the order number and order date for each order that either was placed by Johnson's Department Store or that contains an orderline for a Gas Range. There are orders for a Gas Range and Johnson's Department Store has made orders so there is data to this effect.

Your query is running perfectly, the problem is that there are no matches.


Check the tables. There is no order_num which contains both  '608' and 'DR93'.


If in your query you change 'DR93. for 'BV06' you'll have one match.


Also I recommend you toread about joins.
