Synopsis

Detach a SQL Server Database.

Description

This command detaches one or more SQL Server databases. If necessary, -Force can be used to break mirrors and remove databases from availability groups prior to detaching.

Examples

Example: 1

PS C:\> Detach-DbaDatabase -SqlInstance sql2016b -Database SharePoint_Config, WSS_Logging

Detaches SharePoint_Config and WSS_Logging from sql2016b

Example: 2

PS C:\> Get-DbaDatabase -SqlInstance sql2016b -Database 'PerformancePoint Service Application_10032db0fa0041df8f913f558a5dc0d4' | Detach-DbaDatabase -Force

Detaches 'PerformancePoint Service Application_10032db0fa0041df8f913f558a5dc0d4' from sql2016b. Since Force was specified, if the database is part of mirror, the mirror will be broken prior to
detaching.
If the database is part of an Availability Group, it will first be dropped prior to detachment.

Example: 3

PS C:\> Get-DbaDatabase -SqlInstance sql2016b -Database WSS_Logging | Detach-DbaDatabase -Force -WhatIf

Shows what would happen if the command were to execute (without actually executing the detach/break/remove commands).

Required Parameters

-SqlInstance

The target SQL Server instance or instances.


Alias
Required	True
Pipeline	false
Default Value

-Database

The database(s) to detach.


Alias
Required	True
Pipeline	false
Default Value

-InputObject

A collection of databases (such as returned by Get-DbaDatabase), to be detached.


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

-UpdateStatistics

If this switch is enabled, statistics for the database will be updated prior to detaching it.


Alias
Required	False
Pipeline	false
Default Value	False

-Force

If this switch is enabled and the database is part of a mirror, the mirror will be broken. If the database is part of an Availability Group, it will be removed from the AG.


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

-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.


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.


Alias	cf
Required	False
Pipeline	false
