function Stop-DbaProcess { <# .SYNOPSIS This command finds and kills SQL Server processes. .DESCRIPTION This command kills all spids associated with a spid, login, host, program or database. If you are attempting to kill your own login sessions, the process performing the kills will be skipped. .PARAMETER SqlInstance The SQL Server instance. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or 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 Spid Specifies one or more spids to be killed. Options for this parameter are auto-populated from the server. .PARAMETER Login Specifies one or more login names whose processes will be killed. Options for this parameter are auto-populated from the server and only login names that have active processes are offered. .PARAMETER Hostname Specifies one or more client hostnames whose processes will be killed. Options for this parameter are auto-populated from the server and only hostnames that have active processes are offered. .PARAMETER Program Specifies one or more client programs whose processes will be killed. Options for this parameter are auto-populated from the server and only programs that have active processes are offered. .PARAMETER Database Specifies one or more databases whose processes will be killed. Options for this parameter are auto-populated from the server and only databases that have active processes are offered. This parameter is auto-populated from -SqlInstance and allows only database names that have active processes. You can specify one or more Databases whose processes will be killed. .PARAMETER ExcludeSpid Specifies one or more spids which will not be killed. Options for this parameter are auto-populated from the server. Exclude is the last filter to run, so even if a spid matches (for example) Hosts, if it's listed in Exclude it wil be excluded. .PARAMETER ProcessCollection This is the process object passed by Get-DbaProcess if using a pipeline. .PARAMETER 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. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER 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. .NOTES Tags: Processes Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Stop-DbaProcess .EXAMPLE Stop-DbaProcess -SqlInstance sqlserver2014a -Login base\ctrlb, sa Finds all processes for base\ctrlb and sa on sqlserver2014a, then kills them.
