Required Parameters

-SqlInstance

The target SQL Server instance or instances. You must have sysadmin access and server version must be SQL Server version 2012 or higher.

Alias
Required True
Pipeline true (ByValue)
Default Value

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.

Alias
Required False
Pipeline false
Default Value
-AvailabilityGroup

Return only specific availability groups.

Alias
Required False
Pipeline false
Default Value
-IsPrimary

If this switch is enabled, a boolean indicating whether SqlInstance is the Primary replica in the AG is returned.

Alias
Required False
Pipeline false
Default Value False
-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.

Alias
Required False
Pipeline false
Default Value False
