Import [#import] Query Examples[#query-examples]

Import

Use the mongoimport command/tool to import the json documents. For example to import the country profile of Austria (that is, europe/au.json) use

$ mongoimport --db world --collection factbook --file europe/au.json

To import all documents use a shell script. Example import.sh:

#!/bin/bash

MONGOIMPORT=mongoimport
SOURCE     =.           # assume working folder (as root)

function import {
	echo "  importing >${1}<..."
  ${MONGOIMPORT} --db world --collection factbook --file ${1}
}

function import_region {
  for file in ${SOURCE}/$1/*.json
  do
	  import ${file}
  done
}

import_region africa
import_region antarctica
import_region australia-oceania
import_region central-america-n-caribbean
import_region central-asia
import_region east-n-southeast-asia
import_region europe
import_region middle-east
import_region north-america
import_region oceans
import_region south-america
import_region south-asia
import_region world

To check up if all country profiles got imported use a query in the mongo shell e.g.

> use world
  switched to db world
> db.factbook.count()
  261
