SQL++ for Capella Analytics

  • Operational Insights
  • reference
Operational Insights extends the grammar, statements, and capabilities of SQL++ for Analytics used with the Analytics Service in Couchbase Server and Capella. This guide is a reference to the full syntax and semantics of the SQL++ query language that you use with Operational Insights services.

SQL++ for Operational Insights Cloud is a Couchbase implementation, focused on parallel data analysis, of a SQL-for-JSON query language specification called SQL++.

SQL++ for Operational Insights Cloud is similar to SQL. The differences between the languages are due to the differences in the data models that each language is designed to serve. SQL interacts with the flat, schematic world of relational databases, while SQL++ for Operational Insights Cloud interacts with the nested, schema-less or schema-optional world of NoSQL systems like Operational Insights. SQL++ for Operational Insights Cloud is designed to work with the JSON data model.

Grammar-guided explanations, diagrams, and examples of the SQL++ for Operational Insights Cloud language follow.

For an introduction to SQL++, on which SQL++ for Operational Insights Cloud is based, see SQL++ For SQL Users: A Tutorial by Don Chamberlin.
