Course Description

Course Overview

The Transact-SQL Querying – DP-080 course is a specialized program designed to provide participants with comprehensive skills in querying and manipulating data using Transact-SQL (T-SQL) in Microsoft SQL Server. Transact-SQL is a powerful programming language used for managing and querying relational databases. This course focuses on teaching participants how to write efficient and effective T-SQL queries to retrieve, update, and analyze data. Participants will gain a deep understanding of T-SQL syntax, functions, and techniques to optimize query performance and improve database management.

Prerequisites

This course is intended for individuals with a basic understanding of databases and SQL concepts. Participants should have some experience with relational database management systems (RDBMS) and SQL querying.

Methodology

The Transact-SQL Querying – DP-080 course follows an interactive and practical approach. The course includes theoretical lectures, hands-on demonstrations, guided exercises, and real-world scenarios. Instructors will provide step-by-step guidance on writing T-SQL queries, and participants will actively engage in querying databases and solving practical challenges.
