Before you run a mapping that is configured for SQL ELT optimization or a mapping in SQL ELT mode, you can preview SQL queries in the SQL ELT Query panel in the Mapping Designer.
After you configure a mapping and run the preview, Data Integration creates and runs a temporary SQL ELT preview mapping task. When the job completes, Data Integration displays the SQL queries to be executed and any warnings in the SQL ELT Query panel. The warning messages help you understand which transformations in the configured mapping are not applicable for SQL ELT optimization. If SQL ELT query preview fails, Data Integration lists any queries generated up to the point of failure. You can edit the mapping and fix the required transformations before you run the mapping for SQL ELT optimization.
You can also view the temporary job created under My Jobs and download the session log to view the queries generated.
