MongoDB query to search for string like “@email” in the field values
Search for email string using MongoDB find(). Let us create a collection with documents −
> db.demo727.insertOne({UserId:"John@email.com"}); { "acknowledged" : true, "insertedId" : ObjectId("5eab375f43417811278f5898") } > db.demo727.insertOne({UserId:"John@yahoo.com"}); { "acknowledged" : true, "insertedId" : ObjectId("5eab376043417811278f5899") } > db.demo727.insertOne({UserId:"Chris@EMAIL.com"}); { "acknowledged" : true, "insertedId" : ObjectId("5eab376143417811278f589a") }
Display all documents from a collection with the help of find() method −
> db.demo727.find();
This will produce the following output −
{ "_id" : ObjectId("5eab375f43417811278f5898"), "UserId" : "John@email.com" } { "_id" : ObjectId("5eab376043417811278f5899"), "UserId" : "John@yahoo.com" } { "_id" : ObjectId("5eab376143417811278f589a"), "UserId" : "Chris@EMAIL.com" }
Following is the query to search for @email like string −
> db.demo727.find({"UserId":/@email/i});
This will produce the following output −
{ "_id" : ObjectId("5eab375f43417811278f5898"), "UserId" : "John@email.com" } { "_id" : ObjectId("5eab376143417811278f589a"), "UserId" : "Chris@EMAIL.com" }
