Delete a SharePoint list Field(Column) using PowerShell

Delete a SharePoint list Field(Column) using PowerShell

Hello folks,

The following is a code snippet from PowerShell to completely remove or delete a field in a SharePoint list. The code uses the GUID to find the field (column). I tested this with SharePoint 2013.

Approch #1

#Set-ExecutionPolicy RemoteSigned
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
  
Get-PSSnapin –Registered
Add-PSSnapin Microsoft.SharePoint.PowerShell 

#Variables
$SiteURL="xxxxxxxxx"
$ListName="News"
$ColumnName="WikiPlus"
 
#Get Internal Name of the columns
$web = Get-SPWeb $SiteURL
 
#Get the list
$list = $web.Lists.TryGetList($ListName)
 
if($List -ne $null)
{
    #Get the column 
    $column = $list.Fields[$ColumnName]
 
    if($column -ne $null)
    {
        #Reset column properties to allow delete
        $column.Hidden = $false
        $column.ReadOnlyField = $false
        $column.AllowDeletion = $true
        $column.Update()
 
        #Delete the column from list
        $list.Fields.Delete($column)
        write-host "Column has been deleted!" -f Green
    }
    else
     {
        write-host "Specified column name not found!" -ForegroundColor Red
     }
}

Business-critical processes with SharePoint and SQL

SharePoint 2010 provides the ability to connect to backend business systems, surface business data in SharePoint and make it accessible by, and useful to, employees across the organization. Almost every company of significant size uses ERP and CRM solutions to run core business processes. Over time, companies have developed detailed practices around using such systems to support vertical disciplines within the organization (e.g. product planning, financial performance management, supply-chain management, etc.),  yet challenges remain with regard to driving visibility and collaboration, based on business data, across different disciplines and teams. These challenges stem from the fact that only a fraction of employees are licensed and trained to use those backend systems, and from the high cost and complexity of integrating such systems across different functions and teams.
