I used /eclipse-jee-ganymede-SR2-win32/ and it contains Apache Derby plug-in in default. However, when I execute /describe table_name/ statement, "/syntax error:Encountered "describe//" at line 1, column 1/" is encountered unexpectedly. And /show schemas/ statement also not workable because of the same error.
Do other IJ commands work successfully, is it only "describe" and "show" that fail? What does your derby.log say? Describe and Show were added in Derby 10.2, I believe, so they've been there for a long time; is there any possibility that you are running an older release of Derby? thanks, bryan
