HANA Database Explorer/WebIDE - blank results display on calculation view with selection criteria

I have been attempting to complete the exercises from the openSAP HANA development course (github - on my HANA Express 2.0 VM. I have created two calculation views from the exercises with selection criteria that need to be entered when executing the query. In both cases, when I run the query, I get a completely blank screen in the database explorer in WebIDE (PurchaseOrders and SALESORDER_RANKING_AND_DISCOUNT). It's not a screen where it is displaying zero rows - it is completely blank (ie no column names, no grid for results etc). If I remove the selection parameters and just make it a 'select everything' view it works fine and the output displays. As soon as I add the selection parameters back, I get a white screen again and no warnings/error messaging at all.

Is anyone else experiencing this? How would I go about troubleshooting this as I am getting no indication of any error?

  • Hi Lucia

    Thanks for responding. I have attached a screen shot of my results screen in WebIDE (image4.png). If I use 'Open SQL console' instead of 'Open Data', I get the SQL and result set correctly, so I know the query is working. If I remove the variable from the selection, the 'Open Data' option works correctly (image1.png).

    Any ideas?
