More commonly referred to as RegEx, Regular Expressions are incredibly powerful and useful. In this session you will learn why the LIKE function is not RegEx, Quantifiers, Look-aheads and behinds, non-capturing groups, back references, replacements, and more. We will discuss the new built-in functions in SQL Server 2025, and how RegEx can be used in SQL Server 2005 - 2022 via SQLCLR.
