Selecting database inside the JS in MongoDB?
You can use getSiblingDB() from MongoDB for this using var keyword from JS −
anyVariableName= db.getSiblingDB(‘yourDatabaseName’);
Let us implement the above syntax in order to select database −
> selectedDatabase = db.getSiblingDB('sample');This will produce the following output −
Sample
Now, insert some documents. Let’s say the collection is ‘selectDatabaseDemo’ −
> db.selectDatabaseDemo.insertOne({"ClientName":"John Smith","ClientAge":23});
{
"acknowledged" : true,
"insertedId" : ObjectId("5cda794b5667f1cce01d55ad")
}
> db.selectDatabaseDemo.insertOne({"ClientName":"Carol Taylor","ClientAge":24});
{
"acknowledged" : true,
"insertedId" : ObjectId("5cda79565667f1cce01d55ae")
}Display all documents from a collection with the help of find() method −
db.selectDatabaseDemo.find().pretty();
This will produce the following output −
{
"_id" : ObjectId("5cda794b5667f1cce01d55ad"),
"ClientName" : "John Smith",
"ClientAge" : 23
}
{
"_id" : ObjectId("5cda79565667f1cce01d55ae"),
"ClientName" : "Carol Taylor",
"ClientAge" : 24
}
