I hae two tables, related to each other by order id.
I need to find out programatically what orders exist in the main table
without any corresponding lines in the other table based upon the
relationship of the order id.
How can I do a SQL query in which I ask during the join for what does not
exist specifically? Left join, for example, gives me everything; record or
not. Right join would be only if something exists in that second table...
Must be easy, but I can't figure it out.
Thanks!
from #request.cust_table# cu
JOIN #request.orders_table# co on co.customer_id =
cu.cust_id
<cfif url.errorid NEQ 4>
RIGHT OUTER JOIN #request.hold_table# ht on ht.order_id =
co.corder_id
<cfelse>
<!---here....give me what specifically does not have a
record in the other table--->
LEFT OUTER JOIN #request.hold_table# ht on ht.order_id =
co.corder_id
