Update records details using Oracle 10g DB and VB.net - oracle

Question

I am trying to figure out how to get some output as to what records were updated when running this query:
UPDATE CSR.TARGET ces
SET (STATUS_CODE, COMPLETE_DATE, DATA) =
(SELECT 'ERROR', '', REPLACE(c.Data, ' x</csr', '</csr')
FROM CSR.TARGET C
WHERE (c.EID = ces.EID)
AND c.STATUS_CODE = 'ERROR')
WHERE EXISTS (SELECT 1
FROM CSR.TARGET C
WHERE (c.EID = ces.EID)
AND c.STATUS_CODE = 'ERROR')
If there are 3 records that were updated by that above query then i would like to know what they were (record ID, etc). How would i go about doing that?
Currently it just tells me 3 records were updated and thats it. No other details.
Any help would be great! Thanks :o)
UPDATE
I am needing this for a query using VB.net so i do not think i can do PL/SQL type of thing?
Dim OracleCommand As New OracleCommand()
Dim ra As Integer
OracleCommand = New OracleCommand("UPDATE CSR.TARGET ces " & _
"SET (STATUS_CODE, COMPLETE_DATE, DATA) = " & _
"(SELECT 'ERROR', '', REPLACE(c.Data, ' x</csr', '</csr') " & _
"FROM CSR.TARGET C " & _
"WHERE (c.EID = ces.EID) " & _
"AND c.STATUS_CODE = 'ERROR') " & _
"WHERE EXISTS (SELECT 1 " & _
"FROM CSR.TARGET C " & _
"WHERE (c.EID = ces.EID) " & _
"AND c.STATUS_CODE = 'ERROR')", OracleConnection)
Try
ra = OracleCommand.ExecuteNonQuery()
OracleConnection.Close()
....

Answer 1

You should be able to use the RETURNING clause. Assuming that the EID column is the "record ID" you're referring to and that it is numeric
CREATE OR REPLACE TYPE num_tbl
IS
TABLE OF NUMBER;
DECLARE
l_modified_eids num_tbl;
BEGIN
UPDATE csr.target ces
SET <<omitted>>
WHERE <<omitted>>
RETURNING eid
BULK COLLECT INTO l_modified_eids;
<<Iterate through l_modified_eids to see which rows are modified>>
END;

Answer 2

Based on my reading of that query, all records that have an EID that matches the EID of a record who's status_code is 'ERROR' will be udpated. So if you have a table like this:
ID EID STATUS_CODE
-- --- -----------
1 1 ERROR
2 1 OKAY
3 2 OKAY
both records with ID 1 and 2 would be updated, because 2's EID field matches 1's EID field, and 1's EID field shows error. When it updates, it always uses the data from the row with the 'ERROR'.
