Convert Sql Query into Mongodb Query

Question

I have one SQL query written below :

Select * from student where fname + ' ' + lname like '%abc mno%';

How to write the same query in MongoDB?

Answer 1

db.collection.find({"name":/.*abc mno.*/})

OR

db.collection.find({"name":/abc mno/})

You can also use mongo regex

db.collection.find({"name":{'$regex': 'abc mno'}})

Answer 2

Please find below examples,

db.student.find({name:{$regex:"a"}})  //Contain a anywhere

or

db.student.find({name:{$regex:"e$"}}) //Ends with e

or

db.student.find({name:{$regex:"^A"}}) //Start with A
