Answer 1

These all will do the same
create or replace type string_agg_type as object
2 (
3 total varchar2(4000),
4
5 static function
6 ODCIAggregateInitialize(sctx IN OUT string_agg_type )
7 return number,
8
9 member function
10 ODCIAggregateIterate(self IN OUT string_agg_type ,
11 value IN varchar2 )
12 return number,
13
14 member function
15 ODCIAggregateTerminate(self IN string_agg_type,
16 returnValue OUT varchar2,
17 flags IN number)
18 return number,
19
20 member function
21 ODCIAggregateMerge(self IN OUT string_agg_type,
22 ctx2 IN string_agg_type)
23 return number
24 );
25 /
create or replace type body string_agg_type
2 is

4 static function ODCIAggregateInitialize(sctx IN OUT string_agg_type)
5 return number
6 is
7 begin

14 return number
15 is
16 begin
17 self.total := self.total || ',' || value;
18 return ODCIConst.Success;
19 end;
20
21 member function ODCIAggregateTerminate(self IN string_agg_type,
22 returnValue OUT varchar2,
23 flags IN number)
24 return number
25 is
26 begin
27 returnValue := ltrim(self.total,',');
28 return ODCIConst.Success;
29 end;
30
31 member function ODCIAggregateMerge(self IN OUT string_agg_type,
32 ctx2 IN string_agg_type)
33 return number
34 is
35 begin
36 self.total := self.total || ctx2.total;
37 return ODCIConst.Success;

The function can then be incorporated into a query as follows.
