Breaking one row in to mutiple rows

Question

Hi all,
I am doing supplier conversion through ODI.
In legacy one supplier transacts in multiple currencies.
During conversion i have a requirement of creating one supplier site corresponding to each currency.
e.g. if in supplier site table invoice_currency_code is EUR,USD,RUR
then i have to break it in to three rows having invoice_currency_code as
Row1->EUR
Row2->USD
Row3->RUR
We can do the same using PL/SQL.
can we do same using ODI interfaces without procedures or SQL?

Hi,
I don't think that is a simple cartesian...
By my understanding you need to PIVOT the data from on single row to several lines, I create a single query to do it.
Test enviroment:
1) DDL
CREATE TABLE "ODI_TMP_ODS"."TST_PIVOT_CEZAR"
(     "COL_1" VARCHAR2(100) )
2) data
-- INSERTING into TST_PIVOT_CEZAR
Insert into TST_PIVOT_CEZAR (COL_1) values ('a12;b3;c567;d8;e;f;g;h');
Insert into TST_PIVOT_CEZAR (COL_1) values ('I12;J3;L567;M8');
3) query
the "----" is to substitute the spaces once it isn't possible show the spaces here.
--- select row_id,
---------- rtrim(ltrim(resultado, ';'),';') FINAL_RESULT
----- from (select tpc.rowid row_id,
------------------ substr(col_1, instr(col_1, ';', d.lvl - 1), instr(col_1, ';', d.lvl) - instr(col_1, ';', d.lvl - 1)) resultado
------------- from tst_pivot_cezar tpc,
------------------ (select level lvl
--------------------- from dual
-------------------- connect by level < (select max(length(col_1))
------------------------------------------ from tst_pivot_cezar
------------------- ) d
--- where resultado is not null
union all
--- select tpc.rowid row_id,
--------- substr(col_1, -(length(col_1) - instr(col_1, ';', -1))) FINAL_RESULT
------from tst_pivot_cezar tpc
order by row_id
This technique will give you several lines as result that you can associte by the row id.
At ODI you can use it in a procedure step as "insert as select" or as "source select target insert" too in a procedure step.
Does it help you?
