HANA: export table as csv file

Hello experts:

 

I am trying to export table data as .csv file from HANA Studio. I have 'Export as CSV', include dependencies and 'Export to local folder' selected.. The export succeeds, however, the 'exported' directory does not contain a data.csv file. There is a 'data' file, but it's not in csv format.

This previously used to work and the data.csv file used to be created in the local export directory under an 'index' folder. Now the 'index' folder is missing.

Wonder if there's some setting change on HANA Studio that's resulting in this change?

 

Thanks in advance for your help!

Hi folks,

 

In order to fix a couple of issues we are having we have been told we need to upgrade from 48 to version 53.  But we can see that 54 and 55 is now available.  My question is if any of you other folks are on any of these newer releases and if you've had any problems?  I'm trying to read everything I can and discuss before making a decision on which version to upgrade to.

 

Thanks,

Need help with creating a new user/analytic privilege

Hi,

I was trying to create an analytic privilege for a new user I created on the 'hanacloud' '00' system. The analytic privilege is over a calculation view restricting certain shop IDs.

I followed Anooj's recomendation in this thread http://scn.sap.com/thread/3212315 to set the authorizations.

 

But the problem is, if I add the _SYS_BI_CP_ALL along with the privilege that I created then all values in the calculation view are displayed. If I remove it and leave only the AP that I created then I am getting the following error during data preview.

 

"ERROR EXEXUTING THE QUERY

Cannot iterate over result set rows: SAP DBTech JDBC: [2048]: column store error: search table error:  [2950] user is not authorized"

HANA db case sensitivity with SQL text searches

May 3, 2013, 11:38 am

Hi folks,

 

We have a HANA view that users are consuming via Microstrategy.  All fields such as PLANT (WERKS) are case sensitive.  For example if the plant is named 'XYZ1' then the following SQL is NOT returning any results;

 

select * from TABLENAME where WERKS = 'xyz1'

 

Now my microstrategy developer is saying that other databases he consumes are not case sensitive and this setting is configured typically at the database level.  So my question is twofold;

 

1) Is there a database level setting in HANA for case sensitivity?

2) If this option is available does it really make sense to turn this sensitivity off?

 

Thanks,

FileLoader - unable to see uploaded file

May 2, 2013, 2:13 am

Hi, I've created an XS project to use the sap.ui.commons.FileLoader API to upload a file to the XS server. I've included the sap.ui.demokit.FileUploadIntrospector so that I can check if the file has uploaded successfully. Everything looks good but when I test I'm unable to see the file in the Introspector window after I do the upload. The uploadComplete event fires successfully. I verified this by adding in an alert.

 

FileLoader

 

  createContent : function(oController)

      {

            jQuery.sap.require("jquery.sap.resources");

        

              var oPanel = new sap.ui.commons.Panel().setText("File Uploader Test 4");

        

              var oFileUploader = new sap.ui.commons.FileUploader("MyFileLoader");             

              oFileUploader.setUploadUrl("../upload_dir");         

              oFileUploader.setUploadOnChange(true); 

              oFileUploader.attachUploadComplete(oController.doFileLoadComplete);       

              oPanel.addContent(oFileUploader);

  

              var oButton = new sap.ui.commons.Button({

                    id : this.createId("MyButton"), 

                    text : "Upload"

            });

        

              oButton.attachPress(function(){oFileUploader.upload();});         

              oPanel.addContent(oButton);

 

            return oPanel;

 

      }

      

 

FileUploadIntrospector

 

 

<script>

                    var oFileList = new sap.ui.demokit.FileUploadIntrospector({

                          uploadUrl : "../upload_dir-check",

                          autoRefreshInterval : 2000, /* ms */

                          height: '12em',

                          width: '95%'

                    });

                    oFileList.placeAt("upload-check");

              </script>

                  

                                              

 

      </head>

      <bodyclass="sapUiBody"role="application">

              <divid="content"></div>

          

              <h3>Upload Check</h3>

 

                          <p>To verify the results of the upload, check the following file list. It displays all

                          files in the upload area (server side) of this application and is updated automatically.</p>

                          <br><br>

                          <divid="upload-check"></div>

          

                  

          

      </body>

 

 

 

 

After upload I should see the file appear in the introspector window below

 

fileloadertest.JPG

 

 

Any ideas why the file does not show up? Is there any other way to check if the upload worked?

 

To note: I created the folder "upload_dir" in my project as the destination folder for the upload. Is there anything special that I need to set up for this?

Any advice would be appreciated.

SAP HANA - How system understands the columnar data relation?

Hi All,

 

SAP HANA database stores the data in columnar format. So from row based table perspective, each column will be treated as an individual table with distinct values.

   

How HANA database maintains the relationship of each row so the user gets correct data? In other words, how HANA database internally process the column based records?

Is SAP HANA a Hybrid Database?

Hi all,

I'm currently trying to find a thesis question about SAP HANA!
From my understanding SAP HANA is a Hybrid database, having a Column-based store and a Row-based store.

Therefore, I thought we have a duplication of data in 2 (or more) different databases one being Column-based (Or mix) and a Row-based (Or different mix).

Then I found out about HYRISE (Rodent-store: http://ares.epic.hpi.uni-potsdam.de/apps/static/papers/hyrise_hybrid_engine.pdf),

how does HYRISE fit in SAP HANA?

Does SAP HANA follows some HYRISE principals?

 

Thank you guys in advance for the help!

Index on a column store table

May 5, 2013, 3:03 am
$

In a case where performance of particular selects on a specif table is not as good as we may expect, we understand that it could be possible that the creation of an index on a single column of that table, may bring about improved performance.

Before we do this, it would be extremely helpful to know whether it is possible to determine whether that index has been used during query execution. Is this information recorded in the trace files and if so, in which ones?

If not, how should one go about determining whether the addition of the index was successful...other than simply measuring the time taken and making an assumption?

I've searched through copious documentation, blogs, etc, etc but so far I've been unsuccessful in discovering an answer.

Kind regards,

Keith
