<h2 id="synopsis">Synopsis</h2>
<p>Command to return any columns that could potentially contain PII (Personal Identifiable Information)</p>
<h2 id="description">Description</h2>
<p>This command will go through the tables in your database and assess each column.<br />
It will first check the columns names if it was named in such a way that it would indicate PII.<br />
The next thing that it will do is pattern recognition by looking into the data from the table.<br />
Custom scan definitions can be specified using the formats seen in <dbatools module root>\bin\datamasking\pii-knownnames.json and <dbatools module root>\bin\datamasking\pii-patterns.json.</p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
