Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Operation

DBCC Operation to execute - either InputBuffer or OutputBuffer

-SessionId

The Session ID(s) to use to get current input or output buffer.

-RequestId

Is the exact request (batch) to search for within the current session
The following query returns request_id:
SELECT request_id
FROM sys.dm_exec_requests
WHERE session_id = @@spid;

-All

If this switch is enabled, results for all User Sessions will be retreived
This overides any values for SessionId or RequestId

-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.
