Hi all

I've got a process (in c)#) that takes a text file and reads it into a string:
                string fnrdata = "<pre>";
                string fnrLine = "";
                using (StreamReader fnr = File.OpenText(nd[3]))
                {
                  while ((fnrLine = fnr.ReadLine()) != null)
                    fnrdata = fnrdata + fnrLine + "<br>";
                  fnrdata = fnrdata + "
";
}

it then passes fnrdata as a parameter to a stored proc. Everything is peachy-keen until we hit a file that creates a string > 8000 characters. then it horks up with the error ""'String or binary data would be truncated. The statement has been terminated.'"

The stored proc is as follows:
procedure [dbo].[InsertNewFile]
  @SID varchar(8),
  @County varchar(3),
  @TimeRecvd datetime,
  @FileName int,
  @FileData varchar(max) -- parameter for file string
as
begin
  declare @FData varbinary(max)
  set @FData = convert(varbinary(max), @Filedata)
-- the following statements were a suggested solution, which doesn't error, but also doesn't insert the @FileData.  A record IS inserted, but --- the FileData field contains only 52 characters
  --declare @FD varchar(1) = ''
  --set @FD = cast('' as varchar(max)) + @FileData
  --set @FData = convert(varbinary(max), @FD)

  open symmetric key FNSymKey
  Decryption by Certificate FNCert

  if not exists(Select 1 from FNFiles where FileName = @FileName)
    Insert into FNFiles(SID, County, TimeRecvd, FileName, FileData, InsertDate)
    values (@SID, @County, @TimeRecvd, @FileName, 
    EncryptByKey(Key_GUID('FNSymKey'),@FData), getdate())

  close symmetric key FNSymKey
end
Suggestions?
