<h3 id="required-parameters">Required Parameters</h3>
<h5 id="sqlinstance">-SqlInstance</h5>
<p>The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.<br />
If you pass in one availability group listener, all replicas are automatically determined and queried.<br />
If you pass in a list of individual replicas, they will be queried. This enables you to use custom ports for the replicas. <br></p>

are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash.<br></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>
