Thank you REEDPOWELL
I did try this:
SELECT *
FROM table
WHERE
<cfloop list="#condition_id#" index="iii">
condition_id=#iii#<cfif iii is "#trim(ListLast(condition_id))#"><cfelse> and </cfif>
</cfloop>
Or to make clear, exactly as you are suggesting this:
SELECT *
FROM table
WHERE condition_id='c_3' and condition_id='c_13'
But return is 0 records.
