What is SDSQL ?

  SQL Developer is now up to version 4.1 and has had many additions over the years to beef up the sqlplus compatibility.  This is used today by millions of users adding up to millions if not billions of hours in the tool doing their work.  That means our support of core sqlplus has to be very full featured.  One idea we kicked around for a while but never had the time to do was to make our sqlplus engine available on a command line.  The huge benefit of this is that we could then run the actual sqlplus regression tests against our code line.

Enter SDSQL

  We did exactly that.  The guts of SQL Developer's sqlplus support married with a command line interface.  The result is a 10mb download soon with native installers.  That 10mb includes everything you need including the jdbc driver.  Now while replicating sqlplus is interesting and will greatly improve our support for it, it's well boring.  Writing code that does nothing more than mimic other code isn't fun.  So we are adding lots and lots of new things.   The first things you'll notice using sdsql is the arrow keys work, there's history, there's color these and more are just core things we added.  There's also entirely new commands being added and the easiest way to see some of these new things is to use the help command.  The non-sqlplus command are highlighted.  Give them a try.

Here's something added for Bryn which is pretty much obvious yet never been in sqlplus.  I'm in sqlplus and want to change directory to a new path and run some scripts.  In sqlplus, you either exit, cd, and start back up or path all the scripts like @my/other/path/script.sql

Now there's a built in "cd" command.



Here's a quick example.  I start the tool in one path , raptor_common,  then need to run a script in the sub directory.  A quick cd examples then @color.sql.  All host operations are now in that path.  That means running a script, spooling a file, host commands, ...

If you want better output try the script and see why it's named color.sql
