CFQuery with an IN statement (how do you do it)

Question

I have a <cfquery> SQL statement with a 'where in ( )'
clause but quotedValueList can't handle values greater than 1000,
so, how do you do it?
Now, I can't just stick the first query into the second query
to make it work. The first query is more complicated than the
example I gave so that's why I have to break them up. So, how would
I make the second query work if the first query returned 2000
students?
<cfquery name="getStudents" datasource="Oracle">
select pk1
from users
group by pk1
</cfquery>
<cfquery name="getStudentCourses" datasource="Oracle">
select course_id
from course_users
where users_pk1 in (......)
</cfquery>

Answer 1

Well, here is one "method", although it is a major kludge.
You just create a series of OR statements in your 2nd query based
on the number of items returned from your first query. Not elegant
or efficient, but it is strictly "ColdFusion".
<cfquery name="getStudents" datasource="Oracle">
SELECT pk1
FROM users
GROUP BY pk1
</cfquery>
<cfquery name="getStudentCourses" datasource="Oracle">
SELECT course_id
FROM course_users
WHERE 1=0
<cfoutput query="getStudents">
OR users_pk1 = #pk1#
</cfoutput>
</cfquery>
Of course, now you may have a query with 2000 OR lines in it,
so your query might run a little slowly the more items you select
from the first query.
