Regular expressions in SQL Server 2025 - a deep dive

Predavanje je v angleškem jeziku.

Regular expressions are available SQL Server 2025 — and they're worth getting excited about. For years, advanced pattern matching in T-SQL meant wrestling with workarounds and long code. Not anymore. Session will start by comparing regex to the familiar LIKE operator, then go deeper as we explore what makes regex genuinely powerful. SQL Server 2025 ships with seven native functions • REGEXP_LIKE, • REGEXP_REPLACE, • REGEXP_SUBSTR, • REGEXP_INSTR, • REGEXP_COUNT, • REGEXP_MATCHES, and • REGEXP_SPLIT_TO_TABLE We will cover all of them in demos from pattern basics, data validation, extraction from messy text, find/replace, splitting, and performance comparisons, trade-offs and typical caveats.
