ROXIE ECL (Part 1) - Indexes and Queries

Note: This course is the first in a two-part ROXIE series. People who attend the Roxie ECL (Part 1) – Indexes and Queries class, should also attend the Roxie ECL (Part 2) – Complex Query Development. Both classes are presented in the same week.

This class is for developers who want to extend their knowledge of ECL to developing Roxie queries for end-user use. In this course you will learn the benefits of payload indexes as well as use of the indexed joins that make query results fast. Anyone planning to write ECL code to provide final product data to end-users should attend this course.

Course Length: 2 days

Class Prerequisites: Students must have attended the Introduction to ECL (Part 1) - Concepts and Queries, the Introduction to ECL (Part 2) - the Extract, Transform, and Load (ETL) Process, and the Advanced ECL (Part 2) – Super files, Working with XML, and Free-form Text Parsing training classes. Students are welcome to bring their own laptops to take away the code and examples from the class.

  • Defining and Creating INDEXes
  • Using FETCH
  • Creating Roxie Queries (STORED)
  • Testing queries in hThor
