Looping through all the entries of a valiable

Hello Experts,

I am using following select to the data in my Procedure.

tt_cf_ready= select * from "XXXXX"."V_L0_REPLICA"        where SCOPE_OBJECT_DEF_ID = 'check_feasibility'        and   scope_object_status = 'READY' ;

How can can I loop through all the entries of TT_CF_READY and process the data?

What is the best way to do so?

Regards,

Atanu
