### Required Parameters

| Default Value |  |

| Property | Value |
| --- | --- |
| Alias |  |
| Required | True |
| Pipeline | false |
| Default Value |  |

##### -SubscriberSqlInstance

Specifies the SQL Server instance that receives replicated data from the publisher.  
Use this to identify which subscriber instance should have its subscription removed.

| Property | Value |
| --- | --- |
| Alias |  |
| Required | True |

### Optional Parameters

##### -SqlCredential

Login to the target publisher 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.

| Property | Value |
| --- | --- |
| Alias |  |
| Required | False |
| Pipeline | false |
| Default Value |  |

##### -SubscriberSqlCredential

Login to the subscriber instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).  
Required when the subscriber instance uses different authentication than the publisher.  
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.  
For MFA support, please use Connect-DbaInstance.

| Property | Value |
| --- | --- |
| Alias |  |
| Required | False |
| Pipeline | false |
| Default Value |  |

##### -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.

| Property | Value |
| --- | --- |
| Alias |  |
| Required | False |
| Pipeline | false |
| Default Value | False |

##### -WhatIf

If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

| Property | Value |
| --- | --- |
| Alias | wi |
| Required | False |
| Pipeline | false |
| Default Value |  |

##### -Confirm

If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

| Property | Value |
| --- | --- |
| Alias | cf |
| Required | False |
| Pipeline | false |
| Default Value |  |

## Outputs

**None**

This command does not return any objects to the pipeline. It performs the subscription removal operation and displays informational messages via Write-Message and Write-Warning.
