下面说一下,mongodb select的常用操作
测试数据
查看复制打印?
{ "_id" : 1, "title" : "红楼梦", "auther" : "曹雪芹", "typeColumn" : "test", "money" : 80, "code" : 10 }
{ "_id" : 2, "title" : "围城", "auther" : "钱钟书", "typeColumn" : "test", "money" : 56, "code" : 20 }
{ "_id" : 3, "title" : "朝发白帝城", "auther" : "李白", "typeColumn" : "test", "money" : 30, "code" : 30 }
{ "_id" : 4, "title" : "将近酒", "auther" : "李白", "money" : 90, "code" : 40 }
1,取表条数
查看复制打印?
> db.books.count();
4
> db.books.find().count();
4
> db.books.count({auther: "李白" });
2
> db.books.find({money:{$gt:40,$lte:60}}).count();
1
> db.books.count({money:{$gt:40,$lte:60}});
1
php代码如下,按顺序对应的
查看复制打印?
$collection->count(); //结果:4
$collection->find()->count(); //结果:4
$collection->count(array("auther"=>"李白")); //结果:2
$collection->find(array("money"=>array('$gt'=>40,'$lte'=>60)))->count(); //结果:1
$collection->count(array("money"=>array('$gt'=>40,'$lte'=>60))); //结果:1
提示:$gt为大于、$gte为大于等于、$lt为小于、$lte为小于等于、$ne为不等于、$exists不
4000
存在、$in指定范围、$nin指定不在某范围
2,取单条数据
查看复制打印?
> db.books.findOne();
{
"_id" : 1,
"title" : "红楼梦",
"auther" : "曹雪芹",
"typeColumn" : "test",
"money" : 80,
"code" : 10
}
> db.books.findOne({auther: "李白" });
{
"_id" : 3,
"title" : "朝发白帝城",
"auther" : "李白",
"typeColumn" : "test",
"money" : 30,
"code" : 30
}
php代码如下,按顺序对应的
查看复制打印?
$collection->findOne();
$collection->findOne(array("auther"=>"李白"));
3,find snapshot 游标
查看复制打印?
> db.books.find( { $query: {auther: "李白" }, $snapshot: true } );
{ "_id" : 3, "title" : "朝发白帝城", "auther" : "李白", "typeColumn" : "test", "money" : 30, "code" : 30 }
{ "_id" : 4, "title" : "将近酒", "auther" : "李白", "money" : 90, "code" : 40 }
php代码如下
查看复制打印?
/**
* 注意:
* 在我们做了find()操作,获得 $result 游标之后,这个游标还是动态的.
* 换句话说,在我find()之后,到我的游标循环完成这段时间,如果再有符合条件的记录被插入到collection,那么这些记录也会被$result 获得.
*/
$result = $collection->find(array("auther"=>"李白"))->snapshot();
foreach ($result as $id => $value) {
var_dump($value);
}
4,自定义列显示
查看复制打印?
> db.books.find({},{"money":0,"auther":0}); //money和auther不显示
{ "_id" : 1, "title" : "红楼梦", "typeColumn" : "test", "code" : 10 }
{ "_id" : 2, "title" : "围城", "typeColumn" : "test", "code" : 20 }
{ "_id" : 3, "title" : "朝发白帝城", "typeColumn" : "test", "code" : 30 }
{ "_id" : 4, "title" : "将近酒", "code" : 40 }
> db.books.find({},{"title":1}); //只显示title列
{ "_id" : 1, "title" : "红楼梦" }
{ "_id" : 2, "title" : "围城" }
{ "_id" : 3, "title" : "朝发白帝城" }
{ "_id" : 4, "title" : "将近酒" }
/**
*money在60到100之间,typecolumn和money二列必须存在
*/
> db.books.find({money:{$gt:60,$lte:100}},{"typeColumn":1,"money":1});
{ "_id" : 1, "typeColumn" : "test", "money" : 80 }
{ "_id" : 4, "money" : 90 }
php代码如下,按顺序对应的
查看复制打印?
$result = $collection->find()->fields(array("auther"=>false,"money"=>false)); //不显示auther和money列
$result = $collection->find()->fields(array("title"=>true)); //只显示title列
/**
*money在60到100之间,typecolumn和money二列必须存在
*/
$where=array('typeColumn'=>array('$exists'=>true),'money'=>array('$exists'=>true,'$gte'=>60,'$lte'=>100));
$result = $collection->find($where);
5,分页
查看复制打印?
> db.books.find().skip(1).limit(1); //跳过第条,取一条
{ "_id" : 2, "title" : "围城", "auther" : "钱钟书", "typeColumn" : "test", "money" : 56, "code" : 20 }
这根mysql,limit,offset有点类似,php代码如下
查看复制打印?
$result = $collection->find()->limit(1)->skip(1);//跳过 1 条记录,取出 1条
6,排序
查
123f5
看复制打印?
> db.books.find().sort({money:1,code:-1}); //1表示降序 -1表示升序,参数的先后影响排序顺序
{ "_id" : 3, "title" : "朝发白帝城", "auther" : "李白", "typeColumn" : "test", "money" : 30, "code" : 30 }
{ "_id" : 2, "title" : "围城", "auther" : "钱钟书", "typeColumn" : "test", "money" : 56, "code" : 20 }
{ "_id" : 1, "title" : "红楼梦", "auther" : "曹雪芹", "typeColumn" : "test", "money" : 80, "code" : 10 }
{ "_id" : 4, "title" : "将近酒", "auther" : "李白", "money" : 90, "code" : 40 }
php代码如下
查看复制打印?
$result = $collection->find()->sort(array('code'=>1,'money'=>-1));
7,模糊查询
查看复制打印?
> db.books.find({"title":/城/}); //like '%str%' 糊查询集合中的数据

{ "_id" : 3, "title" : "朝发白帝城", "auther" : "李白", "typeColumn" : "test", "money" : 30, "code" : 30 }
php代码如下,按顺序对应的

$param = array("money" => array('$in'=>array(20,30,90)));
$result = $collection->find($param);
foreach ($result as $id=>$value) {
var_dump($value);
}
$param = array("auther" => array('$in'=>array(new MongoRegex('/^李/'),new MongoRegex('/^钱/'))));
$result = $collection->find($param);
foreach ($result as $id=>$value) {
var_dump($value);
}
9,$or
查看复制打印?
