Usage of Execute SQL script step - Pentaho

Hi Team,

I was trying to use the “Execute SQL script” step to execute a Copy statement - feature of Vertica and I would like to perform the following actions in the transformation:

1. Execute an SQL (the copy statement of Vertica database)
2. Based on the result of execution (Need to either lookup a table/file to note the rejects), rollback : if any record is rejected
commit: when all records pass through

My DB connection points to a Vertica Table and I have set the option of Make the transformation database transactional in the Misc tab as well. Despite setting this property to true, I note that multiple Execute SQL steps are opening up multiple connections and are not really considering it to be a single transaction.

Here are few links that have pointed to similar issues in the past which doesn’t have the solution mentioned clearly:

Request you to help me if you have some solution to the same.

Thanks and Regards,
