Скачать или смотреть Replicating Excel Calculations with Virtual Columns in Oracle APEX

In our example we could use this table in many parts of a application. Lets take a look at how an Oracle APEX developer can replicate excel calculations at the table level inside Oracle virtual columns. We wil start by repeating our simple batting average calculation from Example 1. Then add two slightly more advanced calculations for on base percentage (OBP) and slugging (SLG). Last but not least we will touch on a limitation of this approach. You are not able to leverage virtual columns inside other virtual column calculations. For example the baseball stat OPS is a combination of both OBP and SLG. Trying to calculate this as a virtual column will generate a ORA-54012. Don't worry though, part three of this series shows how to build for scenarios like this leveraging Oracle functions.
