Mongo shell commands can be executed in console mode. The inputs are directly forwarded to the native mongo shell and are not formatted or modified by the application.
Client side shell
Here you will find a documentation of the Mongo shell commands: http://docs.mongodb.org/manual/core/crud-introduction/
Server Side Script
In server side script Mode [ S ] can you execute javascript code directly on the server.
// Returns all documents
db.zipcode.find();
// Returns all cities name and sorted by them
db.zipcode.find({}, {city: 1}).sort({city: 1})
// Create a new zipcode document
db.zipcode.insert({_id: '99999', city: 'LEIPZIG', pop: 520838, state: 'SN'})
// Analyze the find-query
db.zipcode.find().explain()
// Show the statistics of the collection
db.zipcode.stats();
There is no pager in console mode. Therefore, all records are loaded for each query. Because this can be a very large amount of data in certain circumstances, the results are limited to 100 documents. It is recommended to use the skip () and limit () functions.
Using a single command, the semicolon at the end is optional.
You can enter multiple commands that have to be included in a function and the result must be returned with the return statement.
function () {
var stats = db.zipcode.stats();
var index = db.zipcode.getIndexes();
return {
stats: stats,
indexInformation: index
};
}
The server side mode only works if the server instance of Mongo runs with enabled server-side JavaScript. It is enabled by default.
