SQLShell accessing Pivotal GemFire XD 1.3

I stumbled open SQLShell recently as per the URL below. Below I will show how you can connect to Pivotal GemFireXD using SQLShell. I used this to export query results using CSV output.

http://software.clapper.org/sqlshell/users-guide.html

Note: Assuming SQLShell is already installed and instructions below are for Mac OSX

1. Create a file in $HOME/.sqlshell/config as shown below, I just took the sample it ships with. Notice how I have added an alias for "gemfirexd", highlighted below.

[db_access]
driver: access
url: jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=/tmp/sample.mdb;DriverID=22}

2. Add Pivotal GemFireXd client driver "gemfirexd-client.jar" to "/Applications/sqlshell/lib"

3. With Pivotal GemFireXD cluster up and running connect and run some commands as shown below.
