When you configure a Target transformation in a mapping in SQL ELT mode, you need to use only a Amazon Redshift V2 connection.
You can configure the following properties in a Amazon Redshift V2 target transformation in a mapping in SQL ELT mode:
Target Connection - Parameter
Operation - Insert, Update, Delete
Truncate Target Table Before Data Load
Require Null Value For Char And Varchar
Copy Options
Treat Source Rows As - Insert, Update, Upsert, Delete
You cannot use the None option. To upsert data, ensure that you select update in the Operation field.
Override Target Query
Schema Name
Target Table Name
Pre-SQL
Post-SQL
