    hql editor comments

    nimo stephan Master

      Does rf-tools support comments in hql-editor?

       

      For example, I write in the hql editor:

       

      line 1: --select DAYNAME(timestamp) from Dates a

      line 3: -- this is a comment

      line 2: select DAY(timestamp) from Dates a

       

      so you see, the first and second line should be ignored.

       

      But it does not work.

       

      I get this failure:
