everbright,
There is a full fledged SQL Editor, not an SQL Editor view.
You can open the editor in many ways:
1) If you open a file with a .sql extension
2) If you’re in the MyEclipse DB Explorer perspective, you will see the option under File > New
This is also always available from File > New > Other > MyEclipse > Database Explorer > SQL File
3) If you bring up the context menu on a connection node in the DB Browser, you will see a “New SQL Editor” option
4) Any of the actions on tables which output scripts will open up the generated script in an SQL editor.
Hope this helps,
Brian.
