Overview

The CALL statement can invoke a system-defined procedure. Ultipa provides a range of built-in procedures for tasks such as managing graph projections, running algorithms, and more.

<call statement> ::=
  "CALL" <procedure reference> [ <yield clause> ]

<yield clause> ::= 
  "YIELD" <yield item> [ { "," <yield item> }... ]

<yield item> ::=
  <column name> [ "AS" <binding variable> ]

Details

• The YIELD clause can be used to select and rename columns from the table produced by the procedure (if applicable), making them available for use reference in subsequent parts of the query.

HDC Graph

An HDC graph resides in the memory of a HDC (High-Density Computing) server, containing either full or partial data from a graphset loaded from the physical storage of shard servers. For more details, refer to HDC Graphs.

Algorithms

Ultipa offers a rich collection of graph algorithms designed for analytical insights from graph data. See Ultipa Graph Analytics & Algorithms.
