首先,我们需要使用mongo命令连接到MongoDB数据库。假设我们的数据库名为test,连接地址为localhost:27017,用户名为user,密码为password,则连接命令如下: mongo localhost:27017/test-uuser-ppassword 1. 连接成功后,我们可以使用以下命令创建一个名为users的集合: db.createCollection("users") 1. 接下来,我们可以向us...
> Need to know the database version? There's a command for that.We didn't find it - ended up using either;<?php$m = new Mongo();$adminDB = $m->admin; //require admin priviledge$mongodb_info = $adminDB->command(array('buildinfo'=>true));$mongodb_version = $mongodb_info['...
To run a database command, you must specify the command and any relevant parameters in a command document, then pass the command document to the MongoDB\Database::command() method. Many database commands return multiple result documents, so the command() method returns a MongoDB\Driver\Cursor...
Most database commands return a single result document, which can be obtained by converting the returned cursor to an array and accessing its first element. The following example executes a ping command and prints its result document: <?php $database = (new MongoDB\Client)->test; $cursor =...
db.repairDatabase(); 8、查看当前使用的数据库 db.getName(); db; db和getName方法是一样的效果,都可以查询当前使用的数据库 9、显示当前db状态 db.stats(); 10、当前db版本 db.version(); 11、查看当前db的链接机器地址 db.getMongo(); 12、Collection聚集集合 ...
thirdly, we input the db.help command, we will find all the method to operate database/ In the above picture, it;s generally used in the development. Notes, in the mongodb, there is no command like mysql ('create database xxx'), instead use command 'use dbname' to create a new db...
$command=$createCollection->getCommand(); $cursor=$manager->executeCommand("databaseName",$command); $response=$cursor->toArray()[0]; var_dump($response); $collstats= ["collstats"=>$createCollection->getCollectionName()]; $cursor=$manager->executeCommand("databaseName", newMongoDB\Driver\...
Please refer below sample code to setup "/as sysdba" when creating JDBC connection to ASM instance. import java.sql.*; import oracle.jdbc.*; import oracle.jdbc.pool.*; // create one DataSource object OracleDataSource ods = new OracleDataSource(); // setup 3 DB properties: user, passwor...
这里mongod就会为我们显示command列表,大约有90多个 上面90多个类中,按其使用场景可以为分如下几类,分别是: - dbcommand.cpp:一般数据库指令,如数据库,索引的创建,重建,打开/关闭等 - dbcommands_admin.cpp:管理指令,如CleanCmd,JournalLatencyTestCmd,ValidateCmd,FSyncCommand - dbcommands_generic.cpp:常用指令,...
此外,也有部分mongos和mongod实例命令不满足上面的命名规范,例如"dropIndexes"、"createIndexes"、"reIndex"、"create"、"renameCollection"等命令,各自命名规则如下: 如上,绝大多数mongos命令源码文件和命令实现类命名相比mongod实例,都带有”cluster”标识,但是还是有部分命令命名不准寻该规则。如果想知道某个命令的源...
