Array Operations

Concepts: sqlArrayOps

Arrays in SQL come with a rich set of functions for inspection, access, and manipulation. These functions treat arrays as first-class data structures, enabling operations that would otherwise require complex joins or procedural code. Inspection Functions CONTAINS() Element Access Performance Characteristics Array operations have different performance profiles depending on whether they need to scan the entire array or can access elements directly. Database Execution Understanding time complexity helps you choose the right function and avoid slow queries on large arrays. Next you will learn how to clean up arrays by removing duplicates and sorting elements into a consistent order.
