<P>This is a useful function for creating lists of
information to return from a query.
example, we pick the list of Centers in Suisun, San Francisco,
and San Diego, using the SQL grammar IN to modify a WHERE
clause rather than looping through the result set after
the query is run.
<CFSET List = "'Suisun', 'San Francisco', 'San Diego'">
<CFQUERY NAME="GetCenters" DATASOURCE="cfsnippets">
SELECT Name, Address1, Address2, City, Phone
FROM Centers
WHERE City IN (#PreserveSingleQuotes(List)#)
</CFQUERY>
<P>We found <CFOUTPUT>#GetCenters.RecordCount#</CFOUTPUT> records.
<CFOUTPUT query="GetCenters">
<P>#Name#<BR>
#Address1#<BR>
<CFIF Address2 is not "">#Address2#</CFIF>
#City#<BR>
#Phone#<BR>
</CFOUTPUT>
