:backends:

• mysql
  :mysql:
  :host : localhost
  :user : root
  :pass : 123456
  :database : config

  :query:
  - select class_name as %{key} from %{ostype} as a,classes as b where a.class_id=b.class_id;
  - select value from node_params as a,nodes as b where a.node_id=b.node_id and b.fqdn='%{::fqdn}' and params='%{key}'

:logger: console

#i want use qurey one to select 'classes'

hiera -c /etc/hiera.yaml -a ostype=Debian classes

['nginx','ntp']

debian server auto include Debian table classes ,this is true.

but query two is not work.

hiera -c /etc/hiera.yaml ::fqdn=squid.example.com nginx::params::config_file_abs_path

it will execut query one language.

so how can make it work? juge filed name is exists in table ?

i want all is work
hiera -c hiera.yaml nginx::params::config_file_abs_path ::fqdn=squid.example.com
["/etc/nginx/nginx.conf"]
