Synopsis

Command to return any columns that could potentially contain PII (Personal Identifiable Information)

Description

This command will go through the tables in your database and assess each column.
It will first check the columns names if it was named in such a way that it would indicate PII.
The next thing that it will do is pattern recognition by looking into the data from the table.
Custom scan definitions can be specified using the formats seen in \bin\datamasking\pii-knownnames.json and \bin\datamasking\pii-patterns.json.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
