How to delete a table from MongoDB database?
Use drop() to delete a table. Following is the syntax −
db.yourCollectionName.drop();
Let us first create a collection with documents −
> db.deleteTableDemo.insertOne({"Name":"Chris","Age":23}); { "acknowledged" : true, "insertedId" : ObjectId("5ccfb705140b992277dae0e6") } > db.deleteTableDemo.insertOne({"Name":"Carol","Age":21}); { "acknowledged" : true, "insertedId" : ObjectId("5ccfb70c140b992277dae0e7") } > db.deleteTableDemo.insertOne({"Name":"David","Age":24}); { "acknowledged" : true, "insertedId" : ObjectId("5ccfb714140b992277dae0e8") }
Following is the query to display all documents from a collection with the help of find() method −
> db.deleteTableDemo.find().pretty();
This will produce the following output −
{ "_id" : ObjectId("5ccfb705140b992277dae0e6"), "Name" : "Chris", "Age" : 23 } { "_id" : ObjectId("5ccfb70c140b992277dae0e7"), "Name" : "Carol", "Age" : 21 } { "_id" : ObjectId("5ccfb714140b992277dae0e8"), "Name" : "David", "Age" : 24 }
Here is the query to delete a table from MongoDB database −
> db.deleteTableDemo.drop();
This will produce the following output −
True
Above, True is returned i.e. the table deleted successfully.
