How can I change query in sqlmap/xxx.xml file?

I'm developing WebSite using Spring framework.

my query is changed in runtime..

--xxx.xml file
SELECT A,B FROM TABLE;     -- CASE A
SELECT A,B,C,D FROM TABLE; -- CASE B
SELECT A FROM TABLE;       -- CASE C 

I want change query CASE A,B,C dynamically. it is possible change query in Java Resource/resource/sqlmap/xxx.xml runtime?

(sorry for short english..)
