Re: Conbine Records Stage

I think solution is in your warning:

"insert a copy operator between the modify and the upstream operator"

Thanks.

Re: date functions

Following will give next Sunday. If you deduct 7 days, you will get previous Sunday.

Next_Day(to_date(date,'dd-mon-yy'), 'Sunday')


Thanks.

Re: Performance Issue

If your table is partitioned and local indexed, you may use tablename PARTITION (partitionname). So query will use only one partition.

2nd option: Add some to your where clause, so that it could reduce the number of records.

Thanks.

Until running the compute statistics on the table stat is not updated. So, you need to add HINTS on your update statement.

Chulett is right. 1st create index on ROW_ID column of the table. After that if still it is slow, then add Index HINTS.

Thanks.

You may use awk command 'length ==200' to separate all records with length 200.

Re: Lookup Stage - wI/O

Since you have only one record for lookup, you can remove lookup and use stage variable in trasformer. Thanks.
