In console mode Mongo shell commands can be executed. The inputs get directly forwarded to the mongo shell and are not formatted or modified by the application.
Here you will find a documentation of the Mongo shell commands: http://docs.mongodb.org/manual/core/crud-introduction/
// 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. These 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 console mode only works if the server instance of Mongo runs with enabled server-side JavaScript. It is enabled by default.
