An easy to use tool for query Oracle database

LINQPad can be used for query Oracle database as well. All you need to do is download IQ Driver for Oracle.
The steps are:
1. Click “Add connection” in the connection tree.
2. Click “View more drivers …” in the “Choose Data Context” dialog
3. Click “Download & Enable Driver” under the “IQ Driver – for MySQL, SQLite, Oracle” section.

In my case, parameters in Advanced tab of IQ Connection need to be populated to be able to connect to Oracle database directly.
