Image repository in HANA

Hello All,

I am trying to build an image repository. The idea is to have a table in HANA DB as shown below and to push the raw data of the image into a BLOB column.

Currently my UI looks something like below(this will eventually change in future)

Am using FileUploader control (sap.ui.commons.FileUploader) and the upload code is as below

  doFileUpload : function(oEvent)  

  {  

            var url = "Services/ImageUpload.xsjs";

            var quesID = sap.ui.getCore().byId("tfQuestionID").getValue();

            var version = sap.ui.getCore().byId("tfVersion").getValue();

            var fileLoader = sap.ui.getCore().byId("FileLoader"); 

              var fileName = fileLoader.getValue(); 

              if (fileName == "" ) 

                { 

                        jQuery.sap.require("sap.ui.commons.MessageBox"); 

                        sap.ui.commons.MessageBox.show("Please choose File.", sap.ui.commons.MessageBox.Icon.INFORMATION, "Information");  

              } 

              else 

              { 

                  url = url+"?file_name="+fileName+"&question_id="+quesID+"&version="+version; 

                  fileLoader.setUploadUrl(url); 

                  fileLoader.upload(); 

              } 

  }

Following is my XSJS server side code to push the image to HANA DB

$.response.contentType = "text/html"; 

try 

{ 

          var conn = $.db.getConnection(); 

          var filename = $.request.parameters.get("file_name");

          var questionID = $.request.parameters.get("question_id");

          var version = $.request.parameters.get("version");

          var imageID = uniqueID();

          var type=filename.substr( (filename.lastIndexOf('.') +1) );;

          var content = $.request.entities.length>0? $.request.entities[0].body:"";

          var size = $.request.entities.length;

          var pstmt = conn.prepareStatement( "insert into \"QIMAGES\" values(?,?,?,?,?,?,?)" );

          pstmt.setString(1,questionID);

          pstmt.setInteger(2,parseInt(version));

          pstmt.setString(3,imageID);

          pstmt.setBlob(4,content);

          pstmt.setString(5,filename);

          pstmt.setString(6,type);

          pstmt.setInteger(7,parseInt(size));

          var rs = pstmt.execute();

          pstmt.close(); 

          conn.commit(); 

          conn.close(); 

          $.response.setBody("[200]"+imageID); 

}  

catch(err) 

{ 

          if (pstmt !== null) 

          { 

                    pstmt.close(); 

          } 

          if (conn !== null) 

          { 

                    conn.close();  

          } 

          $.response.setBody(err.message); 

}

Above server side code to push the image to HANA DB doesn't work! Appreciate your inputs to get this thing work. Thanks for your time.
