LeetCode SQL Solutions – MS SQL Server 🗃️

This repository contains my solutions to LeetCode SQL problems, written and tested using Microsoft SQL Server.

🧠 About

Each solution focuses on:

• Correctness – aligned with LeetCode’s expected results
• Readability – clear SQL formatting and naming
• Performance – where applicable, optimized with proper joins, indexing logic, or CTEs

⚙️ Tested On

• SQL Engine: Microsoft SQL Server 2019+
• Environment: SQL Server Management Studio (SSMS), Azure Data Studio, or online emulators

📌 Note

Some LeetCode problems may use MySQL syntax. When needed, I adapt them to valid T-SQL for MS SQL Server, using equivalents like:

• LIMIT → TOP, OFFSET FETCH
• Date functions: GETDATE(), DATEDIFF(), FORMAT()
• String functions: CHARINDEX, LEFT, RIGHT, etc.
