1、mongodb插入操作
var = var mongoose=require('mongoose');
var db=mongoose.createConnection('mongodb://192.168.152.131:27017/test');
var monSchema=new mongoose.Schema({
name:{type:String,default:'cao'},
age:{type:Number},
sex:{type:String}
});
var monModel=db.model('user',monSchema);
var content={name:"xiami",age:18,sex:'女'};
var monInsert=new monModel(content);
monInsert.save(function(err){
if(err){
console.log(err);
}else{
console.log('写入数据成功');
}
db.close();
});
2、mongodb查找操作
var mongoose=require('mongoose');
var db=mongoose.createConnection('mongodb://192.168.152.131:27017/test');
var monSchema=new mongoose.Schema({
name:{type:String,default:'cao'},
age:{type:Number},
sex:{type:String}
});
var monModel=db.model('user',monSchema);
var content={};
var field={name:"xiami"};
monModel.find(content,field,function(err,result){
if(err){
console.log(err);
}else{
console.log(result);
}
db.close();
});
3、mongodb更新操作
var mongoose=require('mongoose');
var db=mongoose.createConnection('mongodb://192.168.152.131:27017/test');
var monSchema=new mongoose.Schema({
name:{type:String,default:'cao'},
age:{type:Number},
sex:{type:String}
});
var monModel=db.model('user',monSchema);
var info={name:"xiami"};
var update_data={$set:{name:''}};
monModel.update(info,update_data,function(err){
if(err){
console.log(err);
}else{
console.log("update completed");
}
db.close();
});
4、mongodb删除操作
var mongoose=require('mongoose');
var db=mongoose.createConnection('mongodb://192.168.152.131:27017/test');\
var monSchema=new mongoose.Schema({
name:{type:String,default:'cao'},
age:{type:Number},
sex:{type:String}
});
var monMode=db.model('user',monSschema);
var info={name:'xiami'};
var monInsert=new monModel(content);
monModel.remove(info,function(err)){
if(err){
console.log(err);
}else{
console.log('delete ok');
}
db.close();
});
console.log(db);
