Thank you for your Video, which is amazing. Could I ask some questions ?
1. what is the function of using " where 1=1" in the fetch record function ;
2. Could you help to explain a little bit about the cursor, when should we close a cursor and when should we close a cursor
3. why should we have the "staging tables" in the whole process, is it ok to retrieve the tables from the OLTP, and then ETL, and insert them as Dimensional and fact table directly in the datawarehouse
Thank you for your amazing sharing again
