[<CommonParameters>] Description
The Remove-SqlAvailabilityDatabase cmdlet removes availability database from its availability group. The InputObject or Path parameter specifies the availability database.
If you run this cmdlet at the server instance that hosts the primary replica, the cmdlet removes the primary database and all corresponding secondary databases from the availability group.
If you run this cmdlet at a server instance that hosts a secondary replica, the cmdlet removes only the local secondary database from the availability group. The secondary database is no longer joined to the availability group, but other copies of the database continue to be joined.
Examples
Example 1: Remove a database from an availability group
PS C:\> Remove-SqlAvailabilityDatabase -Path "SQLSERVER:\Sql\PrimaryServer\InstanceName\AvailabilityGroups\MainAG\AvailabilityDatabases\Database16"This command removes the availability database named Database16 from the availability group named MainAG.
This command runs on the server instance that hosts the primary replica.
Therefore, it removes the primary database and all its corresponding secondary databases from the availability group.
Data synchronization no longer occurs for this database on any secondary replica.
Example 2: Remove all databases from an availability group
PS C:\> Get-ChildItem "SQLSERVER:\Sql\PrimaryServer\InstanceName\AvailabilityGroups\MainAG\AvailabilityDatabases" | Remove-SqlAvailabilityDatabaseThis command gets all the availability databases that belong to MainAG, and then passes them to the current cmdlet
by using the pipeline operator. The current cmdlet removes each availability database.
Example 3: Remove a secondary database from an availability group
PS C:\> Remove-SqlAvailabilityDatabase -Path "SQLSERVER:\Sql\SecondaryServer\InstanceName\AvailabilityGroups\MainAG\AvailabilityDatabases\Database16"This command removes the secondary database named Database16 from the secondary replica hosted by the
server instance named SecondaryServer\Instance. Data synchronization to the removed secondary databases stops.
This command does not affect the primary database or any other secondary databases.
Example 4: Create a script to remove a database from an availability group
PS C:\> Remove-SqlAvailabilityDatabase -Path "SQLSERVER:\Sql\PrimaryServer\InstanceName\AvailabilityGroups\MainAG\AvailabilityDatabases\Database16" -ScriptThis command creates a Transact-SQL script that removes the availability database named Database16 from the availability group named MainAG.
The command does not perform this action.
Parameters
-AccessToken
The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.
This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance
using a Service Principal or a Managed Identity.
The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.

-Encrypt
The encryption type to use when connecting to SQL Server.
This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.
In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.

-HostNameInCertificate
The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.
This parameter is new in v22 of the module.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
