Does SQL Navigator have an icon for SQL Plus?
SQL Navigator does not have a SQL Plus icon or a feature that can invoke a SQL Plus window and execute your code or statement in that window.
Please invoke SQL Plus via its own shortcut i.e. located in Start Menu | All Programs | Oracle - … | Application Development | SQL Plus.
You might also be able to find the sqlplusw.exe in i.e. “C:\oracle\product\10.2.0\db_1\BIN\sqlplusw.exe” and create a shortcut for it in your Desktop.
If you would like to submit an Enhancement Request for SQL Navigator to add a SQL Plus icon that will automatically invoke SQL Plus window along with your code or statement in it, please open a formal Support Case so that we may process your request.
