SQL Developer 4.1 Early Adopter
You'll need a Java 8 JDK.
There's a new download option - sdscli.
This is a command line version of SQL Developer. We've taken our existing SQL*Plus library in the worksheet and built a command line interface to the database. It's not quite everything that SQL*Plus is, and never will be - but it's also a LOT MORE than SQL*Plus.
Things like statement completion, history recall, new commands, and much more.
We have the QA team running the full library of SQL*Plus regression scripts now and are actively fixing known issues. Feel free to try it out, but we'll let you know when it's time to start reporting bugs. Of course if you have basic questions, feel free.
Here's something to get you started.
Try 'ddl hr.employees'
That will invoke the ddl script engine and produce the DDL for the HR.EMPLOYEES table. Be sure to follow our blogs for more information.
