The ultimate guide to the true order of SQL operations

The SQL language was designed for non-programmers to be able to read a statement and understand what it does. But this has led to a mismatch between the order operations appear in a statement and their logical execution order. This can make writing SQL statements challenging for beginners.

In this session we'll look at the true order of operations in Oracle SQL. Starting with FROM and WHERE, to aggregating data with GROUP BY and HAVING, and defining columns and sorting with SELECT, ORDER BY, and FETCH FIRST. We'll also cover advanced clauses such as WINDOW, PIVOT, and MATCH_RECOGNIZE.

With live demos, this session will show you how the SQL operations work. Join us to learn the relationship between the clauses in SQL queries and help you understand how to write SQL effectively.
