Hi All,
I loaded the below data to a table by adding a new column LOAD_DATE.
How to write the script to delete the data if same day loaded?
For example, loaded the data on today and I want to rerun this job today. Today's data should be deleted and load the data again.
What is the script for this.
Thanks in advance.
This is the source data.
