Advanced ECL (Part 1) – Working with Relational Data
This class examines in detail the ECL functions that make it easy to work with Relational data in the HPCC Systems platform. ECL began as an extremely powerful query language built around easily querying into Relational Data. The techniques taught here reveal that power to its fullest.
Note: This course is the first in a two-part advanced series. People who attend the Advanced ECL (Part 1) – Working with Relational Data class, should also attend the Advanced ECL (Part 2) – Super files, Working with XML, and Free-form Text Parsing. Both classes are presented in the same week.
Course Length: 2 days
Class Prerequisites: Students must have attended the Introduction to ECL (Part 1) - Concepts and Queries and Introduction to ECL (Part 2) – Super files, Working with XML, and Free-form Text training classes. Students are welcome to bring their own laptops to take away the code and examples from the class.
