Find a value in lowercase from a MongoDB collection with documents
To find a value in lowercase, use the toLowerCase() method in MongoDB. Use the method in find() to find the value in lowercase.
Let us create a collection with documents −
> db.demo172.insertOne({"SubjectName":"MySQL"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3838ce9e4f06af551997e1")
}
> db.demo172.insertOne({"SubjectName":"mongodb"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3838d69e4f06af551997e2")
}
> db.demo172.insertOne({"SubjectName":"MongoDB"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3838db9e4f06af551997e3")
}Display all documents from a collection with the help of find() method −
> db.demo172.find();
This will produce the following output −
{ "_id" : ObjectId("5e3838ce9e4f06af551997e1"), "SubjectName" : "MySQL" }
{ "_id" : ObjectId("5e3838d69e4f06af551997e2"), "SubjectName" : "mongodb" }
{ "_id" : ObjectId("5e3838db9e4f06af551997e3"), "SubjectName" : "MongoDB" }Following is the query to find a value in lowercase −
> db.demo172.find({"SubjectName":"MONGODB".toLowerCase()});This will produce the following output −
{ "_id" : ObjectId("5e3838d69e4f06af551997e2"), "SubjectName" : "mongodb" }
