Here are some of the latest tips and advanced concepts for Microsoft SQL Server (MS SQL) in 2024:
1. SQL Server Copilot AI
Microsoft has introduced Copilot AI in SQL Server Management Studio (SSMS), which can assist with generating, optimizing, and explaining SQL queries. This feature is aimed at enhancing productivity for database administrators and developers by leveraging AI capabilities within SSMS【10】【11】.
2. Window Functions
Window functions like ROW_NUMBER, RANK, and DENSE_RANK are powerful for analyzing data over partitions. They are especially useful for tasks like ranking rows within groups and calculating running totals【12】.
3. Common Table Expressions (CTEs)
CTEs simplify complex queries by allowing you to break them into manageable parts. They are also critical for implementing recursive queries, such as navigating hierarchical data like organizational charts or category trees【12】.
4. Performance Tuning
Recent insights recommend focusing on techniques like indexing strategies, query execution plan analysis, and optimizing MERGE versus INSERT, UPDATE, DELETE operations for specific scenarios to improve performance【10】【12】.
5. Temporary Tables and User-Defined Functions (UDFs)
Temporary tables help with intermediate data storage during sessions, while UDFs provide reusable custom logic. These tools can enhance the modularity and efficiency of your SQL code【12】.
6. String and Date Manipulation
Functions like CONCAT, SUBSTRING, and DATEDIFF are valuable for text and date handling, supporting data preprocessing tasks and simplifying reporting operations【12】.
7. Data Import and Export
Modern tools support importing non-traditional data formats, like PDFs, directly into SQL Server databases. These capabilities expand integration options and streamline workflows【10】.
