 You can write a jq expression by connecting :: after the json file name.
 Enclose the jq expression in double quotes if needed.
 
 ```console
 trdsql -oat 'SELECT value, onclick FROM menu.json::".menu.popup.menuitem"'
 ```
+Or specify with the `-ijq` option.
+
+```console
+trdsql -oat -ijq ".menu.popup.menuitem" "SELECT * FROM menu.json"
+```
 
 ```
