Interesting Bug in Oracle SQL Developer

Sat, 17 Jul 2010 00:48:22 GMT

Just came across an intersting bug in Oracle SQL Developer 2.1. In fact it's rather bizarre as it only happens with tables with a single character for a name - like "X" or "Y". I know it's not often you just give a table such a short name as that but I was testing something and just needed a table. Anyway with these tables, they show up fine in the Navigator pane but when you look at the table in the Object Viewer and switch to the Data tab - you can't see the data! Normally you see the column names across the top and the rows down the side. Well, with these single character-named tables you see the rows but not the columns - bizarre!
