SQL Server T-SQL Toolkit

A practical collection of T-SQL demonstrating schema design, stored procedures, indexing, window functions, and a scheduled SQL Agent job — the bread and butter of database work.

Contents

File	Demonstrates
01_schema.sql	Normalized schema (Customers, Orders, OrderItems) with keys, constraints, indexes
02_seed.sql	Sample data for testing
03_stored_procedures.sql	Parameterized procs (CRUD, reporting) with TRY/CATCH + transactions
04_views_and_window_functions.sql	Reporting views, ROW_NUMBER, SUM() OVER, ranking
05_indexing.sql	Covering & filtered indexes with rationale
06_agent_job.sql	A SQL Server Agent job that archives old orders nightly

How to run

Open in SSMS or Azure Data Studio against any SQL Server / LocalDB instance and run the scripts in numeric order.

What this demonstrates

Relational modelling, set-based thinking, safe transactional procedures, reporting with window functions, deliberate indexing, and operational automation via Agent jobs.
