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" }
