A bunch of usefull queries I've found that I need on hand and I think might be usefull for other mongodb n00bs like me :)

I come from the lands of MySql so I will try to add the query I am trying to replicate using mongoose

###Get all

SELECT * FROM cat;

CatModel.find({},function (err,result){
  ...
});

###Get specific fields

SELECT name,color FROM cat;

CatModel.find({},'name color',function(err,data){
 ..
});

###Where clause

SELECT * FROM cat WHERE name = 'Catzinger';

CatModel.find({name:'Catzinger'},function(err,data){
 ...
});

##Next level!

###Count

SELECT count(*) FROM cat ;

Cat.count({},function(err,data){
 ...
});

###Count + where

SELECT count(*) FROM cat WHERE legs = 4;

Cat.count({legs:4},function(err,data){
 ...
});

###Get random row

SELECT * FROM cat ORDER BY RAND() LIMIT 1;; 

var rand = Math.floor(Math.random() * count);
Cat.findOne().skip(rand).exec(callback);
