SQL Server Detach database

    Hi

    I am a SQL Server DBA and have never used Powershell before. I'm trying to detach a database using Powershell, but not getting very far.

    Have read up a bit and most ppl do it like below. I tried to run this, but getting an error that I'm not finding a solution for, so I'm pretty sure I'm doing something very wrong or possibly not doing something that I need to add to the script. Below is what I'm running and the error I'm getting.

    Please if anyone has any suggestions, please let me know.

    PS SQLSERVER:\> [void] [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO")

    PS SQLSERVER:\> $server = new-object Microsoft.SqlServer.Management.Smo.Server('SERVERNAME')

    PS SQLSERVER:\> $server.DetachDatabase("databasename")

    Cannot find an overload for "DetachDatabase" and the argument count: "1".

    At line:1 char:1

    + $server.DetachDatabase("databasename")

    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo : NotSpecified: (:) [], MethodException

    + FullyQualifiedErrorId : MethodCountCouldNotFindBest

    Thanks!

    Looks like you are missing a parameter in the DetachDatabase syntax.

    See this: http://technet.microsoft.com/en-us/library/microsoft.sqlserver.management.smo.server.detachdatabase.aspx

    You need to add a Boolean for the update statistics parameter. Assuming you don't want to do this, it would look like

    $server.DetachDatabase("databasename", FALSE)

    You need to use $false in place of FALSE.
