This course is designed to introduce students to Transact-SQL. Transact SQL is a query language which is used to query databases. Is the standard language used in various software such as Power BI and is a necessity for anyone who is involved in data analysis with data drawn from various sources

The audience for this course is Database Administrators, Database Developers and BI professionals and in general people who draw data from data sources for data analysis.

After completing this course, students will be able to:

• Describe T-SQL, sets, and predicate logic.
• Describe how SQL Server uses data types.
• Write a single table SELECT statement.
• Write a multi-table SELECT statement.
• Write SELECT statements with filtering and sorting.
•  Write DML statements.
• Write queries that use built-in functions.
•  Write queries that aggregate data.
•  Create and implement views and table-valued functions.
•  Use set operators to combine query results.
• Adopt T-SQL to extract/transform data in databases

Module 1: Introduction to T-SQL Querying NPR

This module describes the elements of T-SQL and their role in writing queries. Describe the use of sets in SQL Server. Describe the use of predicate logic in SQL Server. Describe the logical order of operations in SELECT statements.

Module 2: Writing SELECT Queries

This module introduces the fundamentals of the SELECT statement, focusing on queries against a single table.

Module 3: Querying Multiple Tables

This module describes how to write queries that combine data from multiple sources in Microsoft SQL Server.

Module 4: Sorting and Filtering Data

This module describes how to implement sorting and filtering.

Module 5: Working with SQL Server Data Types

This module introduces the data types SQL Server uses to store data.

Module 6: Using DML to Modify Data

This module describes how to create DML queries, and why you would want to.

Module 7: Using Built-In Functions

This module introduces some of the many built in functions in SQL Server.

Module 8: Grouping and Aggregating Data

This module describes how to use aggregate functions.

Module 9: Using Subqueries

This module describes several types of subquery and how and when to use them.

Module 10: Using Table Expressions

Previously in this course, you learned about using subqueries as an expression that returned results to an outer calling query. Like subqueries, table expressions are query expressions, but table expressions extend this idea by allowing you to name them and to work with their results as you would work with data in any valid relational table. Microsoft SQL Server supports four types of table expressions: derived tables, common table expression (CTEs), views, and inline table-valued functions (TVFs). In this module, you will learn to work with these forms of table expressions and learn how to use them to help create a modular approach to writing queries.

Module 11: Using Set Operators

This module introduces how to use the set operators UNION, INTERSECT, and EXCEPT to compare rows between two input sets.
