Connect to WSUS Integrated Database (WID)

Connect locally to the WSUS Windows Internal Database (WID) via the named pipe to run maintenance or reporting against the SUSDB database. WID does not allow remote connections—run tools on the WSUS server with administrative privileges.

Prerequisites

• Run on the WSUS server, elevated (Run as Administrator).
• One of: SSMS, sqlcmd, or the PowerShell SqlServer module.
• Pipe (WID on Server 2012+): \\.\pipe\MICROSOFT##WID\tsql\query
  Database: SUSDB

SSMS (GUI)

1. Start SSMS “Run as administrator”.
2. Server type: Database Engine
   Server name: \\.\pipe\MICROSOFT##WID\tsql\query
   Authentication: Windows Authentication
3. Connect and open a new query window.

Quick smoke test:

SELECT @@VERSION AS SqlEngineVersion, DB_NAME() AS CurrentDatabase;
SELECT TOP (5) name, create_date FROM sys.tables ORDER BY create_date DESC;

sqlcmd (CLI)

:: Run locally on the WSUS server (elevated)
sqlcmd -S np:\\.\pipe\MICROSOFT##WID\tsql\query -d SUSDB -E -Q "SELECT TOP (1) GETDATE() AS ConnectedAt;"

PowerShell (Invoke-Sqlcmd)

Import-Module SqlServer

$Instance = "\\.\pipe\MICROSOFT##WID\tsql\query"
$Database = "SUSDB"

# One-liner test
Invoke-Sqlcmd -ServerInstance $Instance -Database $Database -Query "SELECT TOP (1) GETDATE() AS ConnectedAt;"

# Run a maintenance script
$FileSql = ".\Maintenance.sql"   # e.g., reindex/cleanup queries
Invoke-Sqlcmd -ServerInstance $Instance -Database $Database -InputFile $FileSql
