NVL lets you replace null (returned as a blank) with a string in the results of a query. If expr1 is null, then NVL returns expr2. If expr1 is not null, then NVL returns expr1. Meaning that the output would be replaced by 0. The output still remains as null. https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/NVL.html
