Learn the fundamentals of SQL++ queries for JSON

Use powerful SQL with Couchbase

SQL++ is SQL for JSON with industry-standard ANSI syntax. SQL++ supports common concepts like ACID transactions, hierarchical schema called scopes, and joins across documents. It also takes advantage of our patented cost-based optimization.

Use SQL++ to overcome tough database language challenges

Cost-efficient

Changing queries to a new language is costly. SQL++ meets ANSI 92 standards, which makes SQL migration to Couchbase faster and easier.

Migration tips
Fast

Writing queries can be complex and lead to slow speeds if executed incorrectly. Our cost-based optimizer (CBO) ensures the best performance.

Go faster
Consistent

Using multiple databases for an application leads to data inconsistency. Couchbase can support all your use cases with a single multi-model database.

Familiar

Learning a new proprietary query language for a database is challenging. SQL++ allows developers to use their existing skills in ANSI SQL for JSON.

Customer story

SQL++ database language key capabilities

SQL++ provides teams with powerful ways to interact with data and develop faster queries to support critical applications.

Global Secondary Indexes (GSI)

GSIs enable low-latency queries for interactive applications. They support collection-level processing.

Indexing innovations

Couchbase includes composite and array indexes and a function that identifies the best index for SQL++ queries.

Multi-dimensional scaling (MDS)

MDS delivers workload isolation of various microservices so you can scale out the service you need when you need it.

Full-text search (FTS)

Built-in language-aware text searching enables users to quickly obtain the most relevant documents based on scoring.

SQL++: SQL-like queries with the flexibility of JSON

Develop engaging applications with ease using a comprehensive and declarative JSON query database language. Developers can rapidly adapt to changing business requirements using a schemaless JSON document store.

Query without compromise, with capabilities you expect from SQL queries

SQL++ is a high-performance NoSQL query language with built-in optimizers and indexer enablers to support millions of concurrent interactions with sub-millisecond latencies. Couchbase’s multi-dimensional architecture uses SQL++ across its query, index, search, and analytics services, partitioning to elastically scale data capacity and deliver accelerated query performance.

Familiar tooling makes query development and optimization a breeze

SQL++ is accessed through the Query Workbench and has a built-in index advice feature that tells the developer what indexes are needed to optimize their query. Flex Index uses the inverted search index from the Full-Text Search Service for complicated query predicates. Couchbase also includes a cost-based optimizer and JavaScript-based user-defined functions to manipulate the resulting data.
