This is implemented as of a00c275. It's on a non-master branch though, so until it gets merged, you'll have to build manually to test it.

If you'd like to do that, here's how --

$ git clone https://github.com/kshvmdn/fsql.git $GOPATH/src/github.com/kshvmdn/fsql
$ cd $_
$ git fetch origin
$ git checkout -b refactor/query-structure origin/refactor/query-structure
$ go install .
$ which fsql
$GOPATH/bin/fsql

Merged as of a6c3339, will keep the issue open until confirmation.
