YQL - Overview

YQL (YDB Query Language) is a universal declarative query language for YDB, a dialect of SQL. YQL has been natively designed for large distributed databases, and therefore has a number of differences from the SQL standard.

YDB tools support interfaces for sending YQL queries and receiving their execution results:

• YDB CLI
• YDB SDK

This documentation section contains the YQL reference that includes the sections:

• Data types with a description of data types used in YQL
• Syntax with a full list of YQL commands
• Built-in functions with a description of the available built-in functions

You can also take a tutorial to get familiar with the basic YQL commands, in the section
