Can you please tell me where needs correction.Just a fix would be:
create or replace procedure rel_module_p
as
cursor c is select ID, TYPE, BUILDDATE, DESIGNROOT from o.rel_module;
begin
FOR i in c
LOOP
INSERT into rel_module(id,REL_CompositeParts,DESIGNROOT)
values (i.ID,REL_CompositePart_TAB(REL_COMPOSITEPART(i.type,i.builddate)), i.designroot);
END LOOP;
END;
/However, I'd assume what you want is:
create or replace procedure rel_module_p
as
cursor c is select ID,CAST(COLLECT(REL_COMPOSITEPART(TYPE,BUILDDATE)) AS REL_CompositePart_TAB) REL_COMPOSITEPARTS, DESIGNROOT
from rel_module
group by id,DESIGNROOT;
begin
FOR i in c
LOOP
INSERT into rel_moduleX(id,REL_CompositeParts,DESIGNROOT)
values (i.ID,i.REL_COMPOSITEPARTS, i.designroot);
END LOOP;
END;
