Answer / subhash

we can delete in 2 ways:
1) in TGT Oracle Stage,
select 'Write Mode' as 'DELETE'
and write the delete Query as
"DELETE FROM EMP_TGT
WHERE EID IN (SELECT EID FROM EMP_SRC)"

2)Select 'Write Mode' as 'UPDATE' and write some dummy update query(This statement will not execute as WHERE condition 1=2) as
"UPDATE EMP SER EID='1111' WHERE 1=2"
then write delete query in 'Run before SQL statemets' as
"DELETE FROM EMP_TGT
WHERE EID IN (SELECT EID FROM EMP_SRC)"

We can perform inner join between seq file & oracle stage and then in target oracle stage have write method as Delete where we can specify delete query using orchestrate incoming rows..

Answer / shar

Vaibhav can u plz explain how an sql query is written b/t
seq file and oralce table in oracle stage delete query?

Answer / shilpasagarg

1)The approach is to load the seq file data into one
temporary table say EMP_TEMP. (SEQ -> ODBC Stage (Oracle
(EMP_TEMP table)
EMP_TEMP contains
eid
1
2
"
"
10

2)Then take the ODBC Stage to connect to Oracle DB (EMP
table).
EMP table contains
eid
1
2
"
"
100

Here use the below query to delete the matched EID's
permanantly from oracle DB

DELETE EMP
FROM EMP
INNER JOIN EMP_TEMP
ON EMP.EID=EMP_TEMP.EID
