i m workin with jsp's

i am doing a project on online movie ticket booking system.
i encountered a problem when i started executing code for seat booking....
let me tell u my prob....

i m tryin to execute a query like this....

select s.seatno,'"+seat+"' from booking where s.screenid='101';

seat variable is a string which i got from a checkbox from the previous page...i.e.

<input type="checkbox" name="check" value="<%=sno%>">

i got the seat value from this,

String seat=request.getParameter("check");
out.println(seat);

when i print the value in "seat" i get a value as 's1' which is correct...
the value in "seat" i.e 's1' is one of the column names in my table...
i want to retrieve the data from dat column...
so i used this,

String showno=rst.getString("'"+seat+"'");

when i print the value in showno i m not gettin the data from the column....

i m still getting 's1' which is the column name...
but i want the data from the column...
