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.

  • Course Outline
  • Introduction to Transact-SQL
  • Overview of T-SQL and its role in database querying
  • Understanding the SQL Server Management Studio (SSMS) environment
  • Executing basic T-SQL queries and retrieving data from tables
  • Querying Data with T-SQL
  • Using SELECT statements for data retrieval
  • Filtering and sorting data with WHERE and ORDER BY clauses
  • Working with aggregate functions for data summarization
  • Joins and Subqueries
  • Combining data from multiple tables using JOIN operations
  • Using subqueries to create complex queries and derived tables
  • Understanding common table expressions (CTEs) for query simplification
  • Modifying Data with T-SQL
  • Updating, inserting, and deleting data using T-SQL
  • Understanding transaction management and error handling
  • Implementing best practices for data modification operations
  • T-SQL Performance Tuning
  • Analyzing query performance and identifying bottlenecks
  • Using indexes and statistics for query optimization
  • Employing execution plans to optimize query performance

Outcome

By the end of the Transact-SQL Querying – DP-080 course, participants will be able to:

  • Write efficient and effective T-SQL queries to retrieve and manipulate data.
  • Understand SQL Server Management Studio and navigate the T-SQL environment.
  • Apply various T-SQL techniques for data filtering, sorting, and aggregation.
  • Combine data from multiple tables using JOIN operations and subqueries.
  • Modify data in SQL Server databases and manage transactions effectively.
  • Optimize query performance using indexing and execution plans.
