In this article, we will explore the integration of Visual Studio Code (VS Code) and SQL Server, and how it can help developers write queries efficiently. VS Code is a popular code editor that supports various programming languages, including T-SQL, Python, PHP, AWS CLI, PowerShell, and more. However, to work with these languages in VS Code, we need to use extensions.

For example, when working with T-SQL scripts, it is recommended to install the SQL Server (mssql) extension. This extension provides added functionality for working with T-SQL, such as different color codes for database objects. Without the extension, the script is treated as a regular file.

To install the SQL Server extension, simply click on the recommendation and install it from the marketplace. Once installed, you can add a new connection to SQL Server in VS Code. This allows you to connect to a specific server and database, and view its objects such as tables, views, functions, and stored procedures.

VS Code stores the connection information in a JSON file, which can be accessed through the User Settings JSON. This allows you to view and edit the connection details, and even copy them to set up profiles on new machines or for your colleagues.

One of the exciting features of the VS Code SQL Server extension is the T-SQL IntelliSense. Similar to SSMS and Azure Data Studio, the SQL editor in VS Code provides suggestions for keywords, schema object names, and parameters in stored procedures or functions. It also supports code formatting and style rule inference.

Another useful feature is the ability to peek and go to the definition of schema objects. This allows you to quickly check the script or columns of a table without leaving the editor. Code snippets are also available for performing common T-SQL statements, such as creating a new column, database, or table.

When executing SQL queries, VS Code provides options to view and save the results in different formats, such as CSV, Excel, and JSON. It also supports executing queries in SQLCMD mode, where you can define variables, interact with the operating system, and execute queries with dynamic values.

Overall, the integration of Visual Studio Code and SQL Server provides developers with a powerful tool for writing queries in multiple languages. It eliminates the need for separate editors and provides features like IntelliSense, code snippets, and result visualization. Whether you are a SQL Server developer or working with other programming languages, VS Code is a versatile and efficient choice.
