Cannot open data preview (HANA Studio v2.0.2)

[former_member228641]

hello, I recently encountered an issue with HANA Studio (2.0.2): I cannot preview any data.

After I click on "open data preview" of a table, the system does not show any reaction or warning.

Does anyone have the same problem? What would be the reason? Any hint is highly appreciated.

Hi Ye,

you may have to provide more information about your landscape. Is this happening on test box, how many rows are you trying to display? when you do data preview do  you get message no rows retrieved. please provide also screen shot.

Hi, Lamyae,

thank you for the quick response.

The following error occurs when I clicked "Open Data Preview":

I am using HANA Studio v2.0.2. The tables I am trying to preview are imported from flat files. I can "Open Content" using SQL, but "Open Data Preview" does not retrieve any data from the table.

Let me know if I could provide more information. Thank you very much for your help.

did you just upgrade to HANA Studio v2.0.2, if so was the old one working or not, did this issue happened right after the upgrade? the reason I am asking because I see the entire error message is Java, eclipse related issue which is what the studio build on.

[Former Member · Accepted solution]

it looks to me that the jar files from the old eclipse version, didn't upgrade properly to the new one and when Java tries the linkage it refers to the old Jar files, and because of the incompatibility of the versions it fails, So I am not sure if you have Java programmer who can fix this or you may try to remove and re-install the studio.

Hi Lamyae,

you are right. I uninstalled HANA Studio - v2.0.2 and reinstalled it. Now it works!

I guess upgrading the old version caused the problem. Thank you very much for your help!
