Microsoft has recently unveiled a significant update to the MSSQL extension for Visual Studio Code (VS Code), introducing a suite of features designed to enhance the SQL Server development experience. This update aims to streamline workflows for developers working with Azure SQL, SQL Database in Fabric (Preview), and SQL Server databases.

Key Features of the Update

1. Redesigned Connection Dialog

The new Connection Dialog simplifies database access by offering multiple methods to connect:

  • Direct Parameter Input: Enter server name, database name, username, and password directly.
  • Connection Strings: Input full connection strings for advanced configurations.
  • Azure Resource Browsing: Browse available databases within your Azure account, filtered by subscription, resource group, and location.

Additionally, the dialog maintains a comprehensive history of saved and recent connections, reducing the time required for recurring database access. (infoq.com)

2. Enhanced Object Explorer Filtering

The Object Explorer now includes advanced filtering capabilities, enabling developers to locate specific database objects more efficiently. Filters can be applied based on properties such as name, owner, and creation date, and can be edited or cleared as needed. (infoq.com)

3. Visual Table Designer

The Table Designer offers a visual interface for creating and managing tables, including:

  • Column Management: Add, modify, or delete columns with specified data types and constraints.
  • Primary and Foreign Keys: Define relationships between tables to ensure data integrity.
  • Constraints: Set rules to enforce specific conditions on data entry.

An automatically generated T-SQL script reflects the table design, which can be published directly or executed manually. (infoq.com)

4. Revamped Query Results Pane

The updated Query Results Pane provides:

  • Grid-Based Display: View query results in a grid format with inline sorting.
  • Copy and Save Options: Copy data with or without headers and save results in formats like JSON, Excel, or CSV.
  • Estimated Execution Plans: Preview query execution plans to identify potential performance bottlenecks before running the query. (infoq.com)

5. Query Plan Visualizer

The Query Plan Visualizer allows developers to analyze SQL query performance by displaying detailed execution plans. Features include interactive node navigation, customizable metrics tracking, and the ability to identify bottlenecks and optimize queries effectively. (infoq.com)
