I guess this isn’t really a bug with the beta since it’s also in V5, but I thought I’d mention it anyways.
When using the explain plan tool it’s not currently possibly to comment out a block of sql. For example, if you paste this into the tool and click Generate, you will get an error about the comment not being properly terminated.
SELECT* FROM dual
The “–” will work, but for big blocks this isn’t very convenient. It would really help the way I work (when diagnosing performance issues) to be able to easily comment out big blocks of the query at a time.
