Language for Defining and Processing Data: VQL¶
The SQL Structured Query Language is a standardized database language supported by most relational database managers available on the market.
Virtual DataPort provides a language called Denodo VQL (Denodo Virtual Query Language) which extends SQL with the required capabilities in a distributed information integration environment.
VQL, like SQL, is composed of commands, clauses, operators and aggregation functions. These elements are combined in the instructions to create, update and manipulate databases. This section describes the commands, clauses, operators and syntax of VQL.
