Working with Collections in Oracle PL/SQL from Pluralsight

In this course, we will take an in-depth look at the collection types available in PL/SQL, namely Associative Arrays, Varrays, and Nested Tables. We'll also talk about the bulk fetch and collect features which greatly enhance the performance our PL/SQL code.

Oracle's relational databases are used by thousands of companies around the globe. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural language extension for SQL which allows us to procedurally tie SQL statements to effectively define business logic. In this course, we will talk about collection types available in PL/SQL. Collections Types are an extremely important part of any programming language. The collection types, along with providing a mechanism to conveniently handle sets of data, can also boost performance. Oracle offers a rich set of collection types in Associative Arrays, Varrays, and Nested Tables. We will take an in-depth look at these powerful datatypes and get familiar with the Oracle bulk fetch and collect features which greatly enhance the performance of our PL/SQL code.
