High DPI display and Windows 7

2018-12-14T08:48:56Z

Hi, I am using Denodo 7 vdpadmin on a Windows 7 machine with a 4K display. The application is displayed unscaled and too tiny. I tried both configuration settings in https://community.denodo.com/docs/html/browse/7.0/platform/installation/appendix/launching_the_denodo_standalone_applications_in_high_dpi_displays/launching_the_denodo_standalone_applications_in_high_dpi_displays without effect. Probably these are for Windows 10 only. Is there a way to enable display scaling in Windows 7? Thank you.

Hi Team, Denodo 7.0 Express MS Excel 2010 Format .xlsx Id Name Age City 1 ABC London 2 PQR 20 Sydney 3 LMN 30 Munich 4 XYZ 40 Paris If I chose Start Cell as B1 and End Cell as D4. I get below result: Name Age ABC PQR 20 LMN 30 XYZ 40 Why is city column getting omitted from result set. Is null at C1 the reason ? If I chose Start Cell as B2 and End Cell as D4.

SQL Server recursive query

2018-12-13T15:02:47Z

According to https://community.denodo.com/answers/question/details?questionId=90670000000XcjoAAC&title=Can+denodo+Support+to+recursive+queries+%3F Denodo doesn't support recursive query directly. I am trying to create a base view through the method of "Create base view from query" to workaround this problem, like: select * from option (maxrecursion 0) But I'm getting errors: [BASE] [ERROR] [JDBC WRAPPER] [ERROR] #0 [JDBC ROUTE] [ERROR] Received exception with message 'Incorrect syntax near the keyword 'option'.' Is there a way to workaround this problem? Thanks!

CATALOG_VIEWS() giving wrong results in Localhost

2018-12-13T07:36:14Z

Hi All, I am trying to use CATALOG_VIEWS() to get the list of modified views on a perticular day. Upon the servers, its working fine and giving me the correct results, but in localhost the same query with CATALOG_VIEWS() is giving all the existing views in the output, which are available in the database and are not at all modified. What could be the reson behind this absurd behaviour? or else, I am missing any particular setting/property which needs to be added in my local before using CATALOG_VIEWS()? Please let me know.
