About the Course
Organizations expect data-driven results, but delivering those results requires more than knowing which buttons to click in a reporting tool. Behind every dashboard, every automated report, and every data integration sits a T-SQL query. The professionals who write those queries determine how fast the data arrives, how accurate it is, and how much server resource it consumes. This course covers the full T-SQL development lifecycle: you will learn how to structure queries for readability and maintainability, retrieve and join data across complex relational schemas, filter and aggregate results for precise business answers, manipulate data through INSERT, UPDATE, DELETE, and MERGE operations, and write reusable code through stored procedures, functions, and views.
The course follows a hands-on, progressive methodology that starts with core SELECT statement construction and systematically advances through joins, subqueries, common table expressions, window functions, error handling, transaction management, and performance optimization. You will work with realistic datasets that mirror production environments, write queries that solve actual business problems, and learn to read execution plans that reveal exactly where performance bottlenecks hide. Every module produces a working deliverable: a query, a stored procedure, a function, or an optimization analysis you can adapt and deploy in your own database environment.
This training acknowledges that you work under real constraints: legacy database schemas you inherited but cannot redesign, tight deadlines for ad-hoc reports, large datasets that punish poorly written queries, and stakeholders who need answers in business language rather than database jargon. The exercises and case studies reflect these realities. You will practice writing T-SQL that works in imperfect conditions, handles edge cases gracefully, and communicates results clearly to technical and non-technical audiences alike.
Target Audience
This course is designed for professionals who write, maintain, or depend on T-SQL queries to deliver data, reports, and business intelligence across their organizations.
This course is designed for:
- Database Administrators (DBAs) responsible for writing, reviewing, and optimizing T-SQL queries across production and reporting databases
- Business Intelligence Analysts who build and maintain reports, dashboards, and data extracts from SQL Server data sources
- Data Analysts tasked with retrieving, cleaning, and transforming data for operational and strategic decision-making
- Application Developers who embed T-SQL queries in application code and need to write performant, secure database interactions
- Reporting Specialists who create and maintain SSRS, Power BI, or Excel-based reports driven by T-SQL queries
- ETL/Data Integration Engineers who design and troubleshoot data pipelines using T-SQL for extraction, transformation, and loading
- Systems Administrators who manage SQL Server environments and need stronger query skills for monitoring, troubleshooting, and auditing
- IT Managers and Team Leads who oversee database teams and need to evaluate query quality, performance, and adherence to standards
- Compliance and Audit Professionals who query databases directly to validate data integrity, trace transactions, and generate audit evidence
- Anyone accountable for extracting accurate, timely data from Microsoft SQL Server to support business operations, reporting, or analytics
Course Objectives
This course equips you to design, write, and optimize T-SQL queries and programmable objects that deliver accurate data, support reliable reporting, and perform efficiently at production scale.
By the end of this course, you will be able to:
- Understand the architecture of Microsoft SQL Server and how the query engine processes T-SQL statements from parsing through execution plan generation and result delivery
- Measure query performance using execution plans, SET STATISTICS IO/TIME, and SQL Server Dynamic Management Views (DMVs) to identify bottlenecks and resource-intensive operations
- Design complex multi-table queries using INNER, OUTER, CROSS, and SELF joins combined with subqueries and Common Table Expressions (CTEs) to retrieve precisely the data stakeholders require
- Apply data manipulation language (DML) operations including INSERT, UPDATE, DELETE, and MERGE to manage data changes safely using transactions and error handling patterns
- Develop reusable stored procedures, user-defined functions, and views that encapsulate business logic, enforce consistency, and reduce duplicated query code across teams
- Assess indexing strategies by analyzing clustered, non-clustered, filtered, and covering indexes to determine which structures accelerate your most critical queries
- Set up query performance baselines using DMVs, Query Store, and execution plan comparison to track optimization progress and prevent performance regression over time
- Communicate query results effectively by formatting output for business consumption, building summary aggregations with GROUPING SETS, ROLLUP, and CUBE, and structuring result sets for downstream reporting tools
Requirements & Prerequisites
You should have basic familiarity with relational database concepts such as tables, rows, and columns. Prior exposure to any SQL variant is helpful but not required. Access to a computer with SQL Server Management Studio (SSMS) or Azure Data Studio installed is recommended for hands-on exercises. All sample databases and datasets will be provided during the course.
