I am using simpldb and am trying to save rahul' mehta in simpledb but it is giving me error below :
Code :

   function htmlEscape(text) {
     return text.replace(/&/g,'&').
         replace(/</g,'&lt;').
         replace(/"/g,'&quot;').
         replace(/'/g,'&#039;');
    }
    console.log(params.filename);

  if (params.filename!=undefined) params.filename=htmlEscape(params.filename);
    console.log(sys.inspect(params));
  sdb.putItem(domain, params.objectid, params, function( error ) {
  });

Output :

rahul' mehta

{ 
  filename: 'rahul&#039; mehta',
  }

Error : 

   {"event":"error","errno":"InvalidQueryExpression","message":"The specified query expression syntax is not valid.","queueno":7}

    This error is because you are trying to run Amazon SimpleDB SELECT Query and syntax of that query is wrong. This may be because in query — Attribute Value — must be unclosed with single quotes i.e. ‘Attribute Value’, and again if — Domain Name — and — Attribute Name — contains any special characters then they must be unclosed with acute i.e Domain Name OR Attribute Name. I think you are able to save rahul’ mehta but when you are trying to get that saved attribute-value, you are getting this error. There is nothing wrong this with string you can see it has been saved successfully using SDB Explorer http://www.sdbexplorer.com/
