How to migrate sql server 2000 user defined function returns table

Question

Hi,
How do I capture the SQL Server 200 user defined function that returns table? Is this supported in the current version of Oracle Migration Workbench? I am using the latest version - Release 9.2.0.1.0 with SQL SERVER 2000 plug-in.
I was able to capture the SQL Server 2000 user defined function that returns string and smalldatetime but not the functions return table during the migrate data source stage.
Thanks in Advance,
Susan

Susan,
This is not currently supported. The next release of the Oracle Migration Workbench (due very soon), will do a better job of catching this mad reporting an error. We are looking into a suitable mapping and have created bug # 2355073 - TABLE DEFINITIONS NOT ACCEPTED FOR TABLE FUNCTIONS to track this issue.
Once possible solution we are looking into is using the object type to emulate. Here is an example from the bug:
Original table
SQL> create table tabela (a number, b number, c number, d number);
SQL> insert some values...
SQL> select * from tabela;
A B C D
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
SQL Server 2000 code
CREATE FUNCTION FUNCRETORNATABELA()
RETURNS TABLE
AS
RETURN SELECT A,B,C,D FROM TABELA
SELECT A,B,C,D
FROM FUNCRETORNATABELA()
ORDER BY A
Oracle code (workaround)
SQL> create or replace type MyObjType as object (
2 a number, b number, c number, d number);
3 /
Type created.
SQL> create or replace type MyTabType as table of MyObjType;
2 /
Type created.
SQL> create or replace function teste return Mytabtype pipelined as
2 aa MyObjType := MyObjType(null, null, null, null);
3 cursor c1 is select a,b,c,d from tabela;
4 begin
5 open c1;
6 loop
7 fetch c1 into aa.a, aa.b, aa.c, aa.d;
8 exit when c1%NOTFOUND;
9 pipe row (aa);
10 end loop;
11 close c1;
12 return;
13 end;
14 /
Function created.
SQL> select * from table(teste);
A B C D
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
SQL> select a, c from table(teste) order by c desc;
A C
4 4
3 3
2 2
1 1
