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.





PARAMETERS

-Database [<System.String[]>]

The database(s) to detach.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

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.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Force [<Switch>]

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.



Required? false

-InputObject [<Microsoft.SqlServer.Management.Smo.Database[]>]

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



Required? false

Integrated are all supported.



For MFA support, please use Connect-DbaInstance.

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.
