Sqlserver Expert

This is a solid reference for working with SQL Server, whether you're writing T-SQL or connecting from Node.js with the mssql package. It covers the stuff you actually use: CTEs, window functions, MERGE statements, and parameterized queries that won't get you SQL injected. The system catalog queries are handy when you need to inspect table structures, indexes, and foreign keys without clicking through Management Studio. Best practices section is brief but hits the important points like avoiding SELECT * and using OFFSET/FETCH for pagination. If you're building Node.js apps against SQL Server or just need quick T-SQL patterns, this gets you there without the usual Microsoft documentation maze.
