I got it. I get it done . I have created a view first n then inserting the data to temp tables from a view. create view icare_users_info (oprid,lastname,firstname,department,location,provider_grp_name) as ( select a.oprid , c.last_name , c.first_name , e.descr , d.descr , h.name1 from psoprdefn@icaeurp1 a , psopralias@icaeurp1 b , ps_rd_person_name@icaeurp1 c , ps_location_tbl@icaeurp1 d , ps_dept_tbl@icaeurp1 e , ps_rb_worker@icaeurp1 f , ps_rf_grp_member@icaeurp1 g , ps_rf_provider_grp@icaeurp1 h where a.oprid = b.oprid and b.person_id = c.person_id and f.person_id = b.person_id and f.location= d.location and f.deptid = e.deptid and g.person_id = b.person_id and g.provider_grp_id = h.provider_grp_id ) CREATE TABLE icare_profile_users ( OPRID VARCHAR2(270 BYTE), LAST_NAME VARCHAR2(270 BYTE), FIRST_NAME VARCHAR2(270 BYTE), DEPARTMENT VARCHAR2(270 BYTE), LOCATION VARCHAR2(270 BYTE), PROVIDER_GRP_NAME VARCHAR2(360 BYTE) ) insert into icare_profile_users select * from icare_users_info; This is amazing guys. DB Link has some problem with direct table access, n loves views. Database is our internal HP Database, so there is no connectivity problem. Anyway, important is I get it done. Thank you all. - Chirag On Sat, 16 Oct 2004 13:25:11 +0300, Vinod Gopinath BMMI IS <vinodg@xxxxxxxxxxx> wrote: > Chirag, > ORA-03113 end-of-file on communication channel > > Cause: An unexpected end-of-file was processed on the communication > channel.
