DP-080T00: Querying Data with Microsoft Transact-SQL 

2 Days - Online Instructor Lead

Course Overview 

This course will teach the basics of Microsoft's dialect of the standard SQL language: Transact-SQL. Topics include both querying and modifying data in relational databases that are hosted in Microsoft SQL Server-based database systems, including: Microsoft SQL Server, Azure SQL Database and, Azure Synapse Analytics.

Course outline 


Module 1: Getting Started with Transact-SQL 


In this module you will learn about the basics of the Transact-SQL (T-SQL) language, as well as general properties

properties and terminology of relational databases. This module will also introduce the basic SELECT statement for 

retrieving data from a table. 



  1. Introduction to Transact-SQL 

  2. Using the SELECT statement 


Lab : Get started with SQL Server query tools and writing queries in T-SQL 

After completing this module, students will be able to: 

Using a query tool to write and execute queries in Transact-SQL. 

Understand the basic concepts of relational database and the T-SQL language 

Write SELECT statements to retrieve data from a relational database table 

Understand basic datatypes and how they are used 

Understand the basics of NULL values 


Module 2: Sorting and Filtering Query Results 

In the module you will learn how to control what data is returned, the order in which it is returned. You will use the ORDERBY clause, with and without paging. You will learn about various kinds of filters that can be used in the WHERE clause to control which data rows are returned. You will also learn how to manage the results by removing 

duplicates with DISTINCT. 



  1. Sorting query results

  2. Filtering the data 


Lab : Sort and filter data returned by SELECT queries 


After completing this module, students will be able to: 

Use ORDER BY to sort results from a T-SQL SELECT statement. Add a TOP clause to limit the ordered rows returned 

Page the sorted data with OFFSET-FET. Write WHERE clauses to filter the rows returned. 

Use DISTINCT to eliminate duplicate rows in the results 


Module 3: Using Joins and Subqueries 

In this module, you will explore T-SQL queries which access data from multiple tables with varioius kinds of JOIN operations and simple subqueries. 



  1. Using JOIN operations

  2. Using subqueries 


Lab : Write queries with JOIN operations 

Lab : Write SELECT statements using subqueries 


After completing this module, students will be able to: 

Write queries accessing data from multiple tables using JOIN operations. Understand the differences between type of JOIN operations: INNER JOIN, OUTER JOIN, CROSS JOIN. Understand how to join a table to itself with a self-join 

Write subqueries within a SELECT statement. Understand the difference between scalar and multi-valued subqueries 

Understand the difference between correlated and self-contained subqueries 


Module 4: Using Built-in Functions 


In the module you will explore the use of built-in functions for returning computed or special values in the

SELECT list or in the WHERE clause. Functions include math functions, string functions and system functions. There are other types of functions that will be mentioned, but not discussed in detail. You will also learn how to combine rows 

of data into a single group, providing summary information for the group such as SUM, MIN or MAX. 



  1. Getting started with scalar functions

  2. Grouping aggregated results 


Lab : Built-in functions 


After completing this module, students will be able to: 

Write queries using scalar functions. Write queries using aggregate functions. Use GROUP BY to combine data into groups based on a common column value. Understand how HAVING is used to filter groups of rows 


Module 5: Modifying Data 


In this module, you will learn the T-SQL statements for modifying table data including UPDATAE, DELETE and

MERGE as well as various options for INSERT including creating a new table with data from an existing table. You will also 

look at how to have the system automatically supply values for columns as the data is inserted. 



  1. Inserting data into tables 

  2. Modifying and deleting data 


Lab : Modify data 


After completing this module, students will be able to: 

Insert data into an existing table. Specify that a column should be automatically populating with an IDENTITY 

or a SEQUENCE value 

Modify data using the UPDATE statement 

Delete data using the DELETE statement 

Modify data using MERGE to synchronize two tables 

Audience Profile 

This course can be valuable for anyone who needs to write basic SQL or Transact-SQL queries. This includes

anyone working with data as a data analyst, a data engineer, a data scientist, a database administrator or a database developer. It can also be useful for others peripherally involved with data, or wanting to learn more about working with 

data such as solution architects, students and technology managers.
