{
<#
.SYNOPSIS
Automatically installs or updates sp_WhoIsActive by Adam Machanic.
 
.DESCRIPTION
This command downloads, extracts and installs sp_whoisactive with Adam's permission. To read more about sp_WhoIsActive, please visit:
 
Updates: http://sqlblog.com/blogs/adam_machanic/archive/tags/who+is+active/default.aspx
 
Also, consider donating to Adam if you find this stored procedure helpful: http://tinyurl.com/WhoIsActiveDonate
 
.PARAMETER SqlServer
The SQL Server instance.You must have sysadmin access and server version must be SQL Server version 2000 or higher.
 
.PARAMETER SqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
 
$scred = Get-Credential, then pass $scred object to the -SqlCredential parameter.
 
Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user.
 
.PARAMETER OutputDatabaseName
Outputs just the database name instead of the success message

.EXAMPLE
Install-SqlWhoIsActive -SqlServer sqlserver2014a -Database master
 
Installs sp_WhoIsActive to sqlserver2014a's master database. Logs in using Windows Authentication.
  
.EXAMPLE
Install-SqlWhoIsActive -SqlServer sqlserver2014a -SqlCredential $cred
 
Pops up a dialog box asking which database on sqlserver2014a you want to install the proc to. Logs into SQL Server using SQL Authentication.
  
 
.EXAMPLE
$servers = Get-SqlRegisteredServerName sqlserver
Install-SqlWhoIsActive -SqlServer $servers -Database master
 
This command doesn't support passing both servers and default database, but you can accomplish the same thing by passing an array and specifying a database.
