How many bad business decisions could be avoided if your data was accurate, timely, and easy to query? Nearly 82% of organizations admit to basing decisions on out-of-date data, leading to costly mistakes. The Querying Data with Transact-SQL training course builds the skills you need to work confidently with Microsoft SQL Server.
Through hands-on, instructor-led training, you’ll learn to query single and multiple tables, filter and sort results, join related data, use built-in functions, and work with stored procedures and transactions. You’ll also master subqueries, table expressions, aggregations, and error handling, ensuring you can retrieve and manage data accurately, securely, and efficiently.
This course will give you the practical skills to retrieve, manipulate, and manage data using Transact-SQL in Microsoft SQL Server. You’ll gain experience in writing efficient queries, combining data from multiple sources, and applying advanced features for accuracy and performance.
By the end of this course, you will be able to:
Write single-table and multi-table SELECT queries with filtering and sorting
Use JOINs, subqueries, and table expressions to combine and structure data
Apply built-in, aggregate, and window functions for analysis
Work with stored procedures, parameters, and transactions
Implement error handling and best practices for reliable query execution
