By the end of this post, you will have a good understanding of how to use N1QL to work with your Couchbase data.

What is N1QL Programming Language?

N1QL, pronounced as “nickel,” is a query language designed for querying and manipulating data stored in NoSQL databases, particularly in Couchbase Server. N1QL stands for “Non-First Normal Form Query Language.” It provides a structured and expressive way to interact with JSON data, which is commonly used in NoSQL databases.

N1QL is SQL-like in its syntax and functionality, making it easier for developers and database administrators who are familiar with SQL to work with NoSQL databases like Couchbase. With N1QL, you can perform tasks such as retrieving data, filtering, sorting, aggregating, and updating documents stored as JSON objects in Couchbase.
