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
