All possible combinations of a column as applied to a unique entry?

Question

i am having trouble getting a loop to do what i want, if you
can help me find out what i am doing wrong i would appreciate it:
i have a database with 3 tables in it
table 1 has a list of documents - each one having a primary
key
table 2 has a list of document properties, i will call them
property A, B, and C - each one having a primary key
table 3 is a "relational" table that has a column for a
document's PK and a property's PK that that document has
Example of table 3:
docPK / propPK
1 (Document 1) / 1 (A)
2 (Document 2) / 1 (B)
3 (Document 3) / 2 (B)
1 (Document 1) / 2 (B)
1 (Document 1) / 3 (C)
i need to create a loop in ColdFusion that spits out the
number of possible combinations that exist for each document
so the correct output should look like:
Property A
Document 1
Property B
Document 1
Document 2
Document 3
Property C
Document 3
Property A, Property B
Document 1
Proberty A, Property B, Property C
Document 1
this output displays all possible combinations of properties
under the conditions of existing documents
here is the loop i have so far that does not seem to be
working for me,
<cfoutput query="rsProperties">
<ul>
<cfloop from="0" to="# of properties per document"
index="i">
<li>
<cfoutput group="propPK">
<cfif i EQ "# of properties per document">
[#Trim(propertyName)#]
</cfif>
</cfoutput>
</li>
<ul>
<cfoutput group="docPK">
<li><a href="">#Document
Name#</a></li>
</cfoutput>
</ul>
</cfloop>
</ul>
</cfoutput>
my loop returns possible combinations, but it is not
returning ALL possible combinations, for example it may only return
Property A as a single instead of also returning singles Property B
and C
my query simply consists of a SELECT * FROM [the database]
WHERE [the three tables are set equal (as a join)] AND WHERE
[documents exist]
i know this is all rather confusing but if you can help me
make sense of it i will be grateful
thanks for your time

Read the cfoutput section of the cfml reference manual. If
you don't have one, the internet does.
Look for the example that shows you how to use the group
attribute.
