Set variable value in MongoDB save() method
Use db.yourCollectionName.save(yourVariableName) to set variable value, wherein “yourVariableName” is your variable.
Let us see an example and create a variable −
> var Info={"Name":"David",
... "CountryName":"US",
... "ProjectDetails":[{"ClientName":"David","ProjectName":"Online Banking System"}]}Following is the query to set the variable value in the save() to save the value in the collection −
> db.demo483.save(Info);
WriteResult({ "nInserted" : 1 })Display all documents from a collection with the help of find() method −
> db.demo483.find().pretty();
This will produce the following output −
{
"_id" : ObjectId("5e82e0d6b0f3fa88e22790a0"),
"Name" : "David",
"CountryName" : "US",
"ProjectDetails" : [
{
"ClientName" : "David",
"ProjectName" : "Online Banking System"
}
]
}
