You can achieve this in two ways using execute sql task.
1.Insert data into global temporary table,then use execute sql task update your target table with join temporary table and can also insert data to your target table using temporary table.
2. Insert data into in dummy table(database) then update and insert target table using this dummy table. You can use merge statement for insert and update.
