Powershell and SQL Help

I have wriiten the following SQL script to execute using powershell. But getting error:

cls
foreach ($svr in get-content "demo.txt")
{
  $con = "server=MC1-PQ10X.RF.LILLY.COM\SQL01;database=mylilly_WSS_Content_INCTSK0014840;Integrated Security=sspi" 

  $cmd = "SELECT DocVersions.TimeCreated
FROM DocVersions FULL OUTER JOIN Docs ON Docs.Id = DocVersions.Id
--   INNER JOIN Webs On Docs.WebId = Webs.Id
--INNER JOIN Sites ON Webs.SiteId = SItes.Id
WHERE (DirName LIKE '%globalcontentrepository%')
AND (IsCurrentVersion = '0')
AND (DocVersions.Id IN ('$svr')"

  $da = new-object System.Data.SqlClient.SqlDataAdapter ($cmd, $con)

  $dt = new-object System.Data.DataTable

  $da.fill($dt) |out-null

  $dt | Format-Table -autosize

 }

The error I'm getting is:

Exception calling "Fill" with "1" argument(s): "Incorrect syntax near ')'."
At line:18 char:11
+   $da.fill <<<< ($dt) |out-null
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

Kindly look into this and give ur suggestions.
