Use "SELECT" command to executes a select SQL statement. The shell uses a logging view to display the result for now (table view will be supported in the future and users will be allowed to choose among various views by the SET command).  User can press SPACE to pause the view from scrolling or resume displaying. When the view is paused, data accumulates in the buffer.

Use "EXECUTE" command to executes a SQL file. All the SELECT statements in the file will be omitted as executing streaming SELECT statements in a batch doesn’t make sense.

SET: Use “SET” command to display the name and value of all environment variables that impacts the behavior of the shell and the "SqlExecutor". Use “SET <<name>=<value>>” to set a variable.  These environment variables can also be set in the configuration file, namely "conf/shell-defaults.conf".
