  Hello

  I am searching for a Powershell script which picks Windows Server names from SQL server table(eg: Instance.DB.tbServerList) & writes last reboot date to SQL server table(can be same or different table)

  Can someone help me in this?

  Cheers,

  Sree

  --Create test database and table.

  CREATE DATABASE Test

  GO

  USE Test

  GO

  CREATE TABLE dbo.tbServerList (Srv sysname, lastRebootDate datetime)

  GO

  --Replace server names as required.

  INSERT dbo.tbServerList (Srv)

  VALUES ('Srv1'),('Srv2');

  GO

  /** Run PowerShell script **/

  --Check results.

  SELECT

  Srv

  ,lastRebootDate

  FROM dbo.tbServerList;

  GO

  Here is the PowerShell script.

  $inst = 'yourServer'

  $DB = 'Test'

  #Import the sqlps module to allow use of invoke-sqlcmd.

  Import-Module “sqlps” -DisableNameChecking

  $srvList = invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SELECT Srv FROM dbo.tbServerList;" | %{'{0}' -f $_[0]}

  foreach ($srv in $srvList)

  {

  $rebootDate = invoke-sqlcmd –ServerInstance $srv -Query "SELECT sqlserver_start_time FROM sys.dm_os_sys_info;" | %{'{0}' -f $_[0]}

  invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SET dateformat dmy; UPDATE dbo.tbServerList SET lastRebootDate = '$rebootDate' WHERE Srv = '$srv';"

  }

  Try this:

  $inst = 'yourserver'

  $DB = 'Test'

  #Import the sqlps module to allow use of invoke-sqlcmd.

  Import-Module “sqlps” -DisableNameChecking

  $srvList = invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SELECT Srv FROM dbo.tbServerList;" | %{'{0}' -f $_[0]}

  foreach ($srv in $srvList)

  {

  $os = Get-WmiObject win32_OperatingSystem

  $rebootDate = $os.ConvertToDateTime($os.lastbootuptime)

  invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SET dateformat mdy; UPDATE dbo.tbServerList SET lastRebootDate = '$rebootDate' WHERE Srv = '$srv';"

  }

  Sorry, I had removed the -ComputerName switch during testing.

  $inst = 'yourServerName'

  $DB = 'Test'

  #Import the sqlps module to allow use of invoke-sqlcmd.

  Import-Module “sqlps” -DisableNameChecking

  $srvList = invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SELECT Srv FROM dbo.tbServerList;" | %{'{0}' -f $_[0]}

  foreach ($srv in $srvList)

  {

  $os = Get-WmiObject win32_OperatingSystem -ComputerName $srv

  $rebootDate = $os.ConvertToDateTime($os.lastbootuptime)

  invoke-sqlcmd –ServerInstance $inst -Database $DB -Query "SET dateformat mdy; UPDATE dbo.tbServerList SET lastRebootDate = '$rebootDate' WHERE Srv = '$srv';"

  }

  Run this to see all your history... and no UI necessary

  get-eventlog System | where-object {$_.EventID -eq "6005"} | sort -desc TimeGenerated
