Clear-Host 

$tb =  Invoke-Sqlcmd2 -ServerInstance YourSQLInstance -Database Adventureworks2008 -Query 'Select FileName, Document from [Production].[Document] where document is not null '  -as 'DataTable'
#$tb.rows.count 
for ($i=0;$i -lt $tb.rows.count;$i++) {
	
	$TheDoc = $tb.Rows[$i].Document 
	$TargetFile = $('c:\temp\Export_{0}' -f $tb.Rows[$i].FileName )
	#$TheDoc.Length 
	[System.IO.File]::WriteAllBytes($TargetFile,$TheDoc)
}

Write-Host $("[{0}] documents exported" -f $tb.rows.count )
