asp_web_howto thread: Using more than one query

In Access, you can easily build a query which you then use inside another
query to get results.
But how do you transfer this solely into SQL code?
We prefer to keep all the source SQL code in the ASP pages, rather than
stored queries in Access, but if I delete them, it doesn't work.
For example: (This is using the results of another query "1stWeek" before
comparing)
SELECT DISTINCTROW [1stweek].DiaryID, [1stweek].WeekStart,
[1stweek].Firstname, [1stweek].Surname, [1stweek].Recno
FROM 1stweek LEFT JOIN [2nd Week] ON [1stweek].Recno = [2nd Week].Recno
WHERE ((([2nd Week].Recno) Is Null));
I need really the SQL source for both queries, but I'm not sure how to do
this in ASP as Access runs one query, then the other. How is this replicated
in true ASP/SQL?
Cheers
Craig.

Tip1: Never use special characters(spaces, -, $, etc...) in columns or table
names "2nd Week".
Tip2: Use underscores where you would normally use spaces "2nd_Week".
Tip2: Never use integers to start a column or table name.
Try this (untested)
SELECT DISTINCT A.DiaryID,A.WeekStart,A.Firstname,A.Surname,A.Recno
FROM week1 A, Week2 B
Where A.Recno = B.Recno
AND B.Recno Is Null
