the escape character in the  where clasue fileter  on logical layer

My application requires "WHERE Clause" filter on logical layer 's table where an in-list is passed from a session variable.

for example , I get an session named "UserList" as ( 'jack','ken');

and I want to filter the information by the Userlist, but it seems has have escape charater problem, the single quote will cause problem.
it work all right when I add " 'jack','ken' " manually in where caluse, but if I use VALUEOF(NQ_SESSION."userList") , it failed,


there are some information for your reference:
1. in the answer, I want to know the value of "UserList", here I show it in statc text: @{biServer.variables["NQ_SESSION.UserList"]}

it shows like below
jack','ken

2. in the session vailable initializaiton block, I test it , the "Userlist" work well, it get 'jack','ken' as we expected.
