So, you issue is resolved then, and I don't have to scrutinize your
earlier posts.

Just a comment. I prefer to write the condition as:

NOT EXISTS (SELECT *
FROM tblScanDetail SD
WHERE SD.GUIID = #temp.ID)

There are two problems with NOT IN, that NOT EXISTS does not have:

1) you can get lost when there are NULL values involved.
2) works only with one-column conditions.
