call test report folder wise from Test plan

Hi All, 

I need a report that shows call tests for scripts folder wise... I am able to get the call steps but couldn't figure out how to get them folder wise

Here is my report 

select a.TS_NAME "Test Script", a.ts_test_id " Parent id" , b.TS_NAME "Call test" ,b. ts_test_id "Call Test id",b .ts_description as description ,
dessteps.ds_DESCRIPTION as "Test Step Description" ,
DESSTEPS.DS_STEP_NAME as Step_Name ,
a.ts_exec_status as ' test status'
from TEST a, DESSTEPS, TEST b
where DS_TEST_ID = a.TS_TEST_ID
and b.TS_TEST_ID = DS_LINK_TEST
order by a.ts_name

Any suggestions
