This is my first attempt at programming Excel so please bear with me.
I have a sheet (Sheet3 named "Columns"). On this sheet there are three
columns that I am interested in Table, CodeColumn, Column. Where ever the
value in CodeColumn is not blank I want to form:

SELECT "Column" FROM "Table" WHERE "Column" NOT IN (SELECT "Column" FROM
"CodeColumn")

The quoted names would be the values in the spread sheet. In the end I would
end up with a text file that has the above formated text for each line that
CodeColumn is not blank.

Is this hard? First I am not sure how to specify the sheet, next I don't
know how to iterate through each row in the sheet, and I am not sure how to
output the data to a file (I would be happy with the lines in the clipboard
if that was easiest).

Thank you in advance for your help even if it is just to get me started.
