Help with update,add, delete records

Question

Hi every one,
This is a problems that I have been trying to figure out for
a little while now and I hope you all can help me out. So this is
the situation.
I am useing CFX XLS 2 Query to create a query from an excel
doc I have. Now my problem is how can I loop through and delete the
records that no longer are in the spreadsheet?
So in other words my client will be uploading a new XLS each
day, this xls will have some new data, some of the same and some
will be gone. So I need the system to check and see if the
stocknumber is there, if it is it will just update that record, now
if the record is new it will add the record but for the life of me
I can't figure out how it can delete record.
I had thought maybe doing a select where the stock numbers
dont match but that didnt work out too well :)
Thanks for any help you may be able to provide

You could consider using ValueList() to create a list of
stocknumbers from your excel query, then do something like this:
<cfset sCurrentStockNumbers =
ValueList(myQuery.stocknumber)>
<cfquery name="removeStockNumbers"
datasource="myDataSource">
DELETE from myTable
WHERE stocknumber NOT IN (<cfqueryparam
value="#sCurrentStockNumbers#" list="Yes">)
</cfquery>
