Query in MongoDB to perform an operation similar to LIKE operation
For similar operation, you can use / searchLetter /. Let us first create a collection with documents −
> db.demo26.insertOne({"StudentName":"Chris"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e14c9dc22d07d3b95082e79")
}
> db.demo26.insertOne({"StudentName":"John"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e14c9e022d07d3b95082e7a")
}
> db.demo26.insertOne({"StudentName":"Jones"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e14ca7222d07d3b95082e7b")
}
> db.demo26.insertOne({"StudentName":"David"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e14ca7622d07d3b95082e7c")
}Display all documents from a collection with the help of find() method −
> db.demo26.find();
This will produce the following output −
{ "_id" : ObjectId("5e14c9dc22d07d3b95082e79"), "StudentName" : "Chris" }
{ "_id" : ObjectId("5e14c9e022d07d3b95082e7a"), "StudentName" : "John" }
{ "_id" : ObjectId("5e14ca7222d07d3b95082e7b"), "StudentName" : "Jones" }
{ "_id" : ObjectId("5e14ca7622d07d3b95082e7c"), "StudentName" : "David" }Following is the query to use the “LIKE” statement in MongoDB −
> db.demo26.find({"StudentName":/Jo/});This will produce the following output -
{ "_id" : ObjectId("5e14c9e022d07d3b95082e7a"), "StudentName" : "John" }
{ "_id" : ObjectId("5e14ca7222d07d3b95082e7b"), "StudentName" : "Jones" }
