Example usage
var MongoDB = require("mongodb");
var db = new MongoDB.Mongo().getDB("mydb");
var colls = db.getCollectionNames();
colls.forEach(function(el) { print(el); });
var coll = db.getCollection("testCollection");
coll.drop();
var doc = {
"name" : "MongoDB",
"type" : "database",
"count" : 1,
"info" : {
x : 203,
y : 102
}
}
coll.insert(doc)
myDoc = coll.findOne();
print(myDoc);
// Now, lets add lots of little documents to the collection so we can explore queries and cursors
for (var i=0; i < 100; i++) {
coll.insert({"i": i});
}
print(coll.getCount());
// Let's get all the documents in the collection and print them out
var cur = coll.find();
while(cur.hasNext()) {
print(cur.next());
}
// Now use a query to get 1 document out
var query = { i: 71 };
cur = coll.find(query);
while(cur.hasNext())
print(cur.next());
// Now use a query to get a larger set
query = { "i": { "$gt": 50 } }; // i.e. find all where i > 50
cur = coll.find(query);
while(cur.hasNext())
print(cur.next());
