I have the following values stored in a comma delimited list... for example

list: 13,14,16,18

there is a url variable #fc# that i need to find in the database field containing this list (named teams_selected).  I tried to write a query to do as described but it doesn't seem to be working.

<cfquery>select * from teams_schedule_new where '#fc#' in (teams_selected) order by id desc</cfquery>

Your help is appreciated.

The problem is that the variable "teams_selected" is a string, NOT a comma delimited list of integers.  In order to use the IN construct, you need a COMMA DELIMITED list of values - you need to break the variable teams_selected into its set of separate values, as a collection (the separate values 13, 14, 16 and 18 as individual values.

which does precisely what you need.

Author states teams_selected is a list.

Author is teams_seletced meant to be in ## so as to be evaluated as a variable?

Arthur is right.  teams_selected is right now a string, which is where I was going wrong.  Since I can't understand the link Arthur posted, can someone tell me how to convert the string value to a list so I can properly search it?

select *
from teams_schedule_new
where teams_selected like '%,#fc#,%'
or ','+teams_selected like '%,#fc#,%'
or teams_selected+',' like '%,#fc#,%'
order by id desc

your last suggestion eliminates records where '13' is the only entry without commas.

Yeah.  Gotta do what you gotta do when the database is not designed right though :)  Glad it worked.
