Report for site collection content database in SharePoint:
On a regular basis, Had to generate report with site collection databases information. PowerShell comes to rescue again!
function SitesInDB([string]$url)

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") > $null
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Administration") > $null

$rootSite = new-object Microsoft.SharePoint.SPSite($url)
$webApplication = $rootSite.WebApplication

$ContentDBCollection = $WebApplication.ContentDatabases

$DBName = [Microsoft.SharePoint.Administration.SPContentDatabase].GetProperty("Name")

#If Data directory already exists remove it
if (Test-Path "D:\Reports\SitesInDB\Data")
    Remove-Item "D:\Reports\SitesInDB\Data" -Recurse

# create a folder
mkdir D:\Reports\SitesInDB\Data

# Traverse through all the content databases and run the stsadm command
foreach($ContentDB in $ContentDBCollection){  
 $CurrentDBName = $DBName.GetValue($ContentDB, $null)
 stsadm -o enumsites -url $url -databasename $CurrentDBName > D:\Reports\SitesInDB\Data\$CurrentDBName.txt

# check the folder "Data-YEAR-MM-DD exists already if so delete it
$newName = get-date -uformat "%Y-%m-%d"
if (Test-Path "D:\Reports\SitesInDB\Data-$newName")
    Remove-Item "D:\Reports\SitesInDB\Data-$newName" -Recurse

#rename the folder "Data" to "Data-YEAR-MM-DD"
ren D:\Reports\SitesInDB\Data D:\Reports\SitesInDB\Data-$newName

#Call the function
sitesInDB ''


  1. can we generate same report using C#?

    1. Sure Tariq, Why not! Here is the code to start with.

      SPWebApplication webApp = SPWebApplication.Lookup(new Uri(""));

      foreach (SPContentDatabase cdb in webApp.ContentDatabases)
      foreach (SPSite oSPSite in cdb.Sites)
      Console.WriteLine("Site:" +oSPSite.RootWeb.Title +" at "+oSPSite.RootWeb.Url + " lives in the database:" + cdb.Name);

  2. Thanks and what about given below properties? how to use?
