jHeidi Alpha 4 has been released and now supports Oracle databases! Basic Oracle browsing support has been implemented along side of the existing MySQL support to allow seamless browsing between the two.
In future releases, additional functionality similar to HeidiSQL MySQL features will be implemented.
jHeidi Alpha 4 is only available from http://jheidi.com/ and not through the auto update process currently.
Ads were blocked - no problem. But keep in mind that developing HeidiSQL, user support and hosting takes time and money. You may want to send a donation instead.
