Udemy – SQL Server 2025 New Dev Features : AI JSON Regex OPPO Fuzzy

This course provides a technical walkthrough of the new developer-centric features introduced in SQL Server 2025. It is designed for developers and database professionals who want to move beyond traditional T-SQL and leverage modern capabilities like AI-driven vector search, native JSON handling, advanced regular expressions, and intelligent query optimization. This is a practical, feature-focused course. We cut through the marketing to focus on syntax, implementation, and performance impact.

What You Will Learn The curriculum is organized into four core modules covering the following technical areas:

• AI & Vector Search: Integration of semantic search capabilities using the native Vector datatype. We cover embeddings with OpenAI, distance functions for similarity searching, and efficient implementation using DiskANN.
• Native JSON & Data Handling: Transitioning from legacy NVARCHAR parsing to SQL Server’s new high-performance native JSON datatype, including native indexing strategies and the JSON_OBJECTAGG function.
• Regex, Text Analytics & Productivity: Implementation of native Regular Expressions (REGEXP_LIKE, REPLACE, SUBSTR, COUNT), practical usage of the || concatenation operator, Base64 encoding/decoding, and Fuzzy Matching algorithms (Edit Distance and Jaro-Winkler).
• Intelligent Query Optimization: Technical deep dive into modern engine tuning. We cover Parameter Sensitive Plan Optimization (PSPO) and Optional Parameter Plan Optimization (OPPO) to address parameter sniffing and ensure consistent query performance.
