Function Update-SPRListItem { <# .SYNOPSIS Updates items from a SharePoint list. .DESCRIPTION Updates items from a SharePoint list. .PARAMETER ListName The human readable list name. So 'My List' as opposed to 'MyList', unless you named it MyList. .PARAMETER Column List of specific column(s) to be updated. If no columns are specified, we'll try to figure out which fields to update. .PARAMETER UpdateObject An object that contains updated fields. This object must have an ID or an alternative KeyColumn. .PARAMETER KeyColumn The column used for update comparisons - similar to a Primary Key in a SQL database. ID by default. .PARAMETER Site The address to the site collection. You can also pass a hostname and it'll figure it out. Don't want to specify the Site or Credential every time? Use Connect-SPRSite to create a reusable connection. See Get-Help Connect-SPRsite for more information. .PARAMETER Credential Provide alternative credentials to the site collection. Otherwise, it will use default credentials. .PARAMETER InputObject Allows piping from Get-SPRListData. .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. .EXAMPLE $updates = Import-CliXml -Path C:\temp\mylist-updated.xml Get-SPRListData -ListName 'My List' -Site intranet.ad.local | Update-SPRListItem -UpdateObject $updates Update 'My List' from modified rows contained within C:\temp\mylist-updated.xml Prompts for confirmation. Uses ID to compare items. .EXAMPLE $updates = Import-CliXml -Path C:\temp\mylist-updated.xml Get-SPRListData -ListName 'My List' -Site intranet.ad.local | Update-SPRListItem -UpdateObject $updates -KeyColumn SSN -Confirm:$false Update 'My List' from modified rows contained within C:\temp\mylist-updated.xml Does not prompt for confirmation.
