- Using SQL Server query tools
- Writing SELECT statements to retrieve columns from one or more tables
- Sorting and filtering selected data
- Using built-in functions to returned data values
- Creating groups of data and aggregate the results
- Modifying data with Transact-SQL using INSERT, UPDATE, DELETE and MERGE
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 and terminology of relational databases. This module will also introduce the basic SELECT statement for retrieving data from a table.
Lessons:
- Introduction to Transact-SQL
- Using the SELECT statement
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 ORDER BY 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.
Lessons:
- Sorting query results
- Filtering the data
Module 3: Using Joins and Subqueries
In this module, you will explore T-SQL queries which access data from multiple tables with various kinds of JOIN operations and simple subqueries.
Lessons:
- Using JOIN operations
- Using subqueries
Lab : Write SELECT statements using 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.
Lessons:
- Getting started with scalar functions
- Grouping aggregated results
Module 5: Modifying Data
In this module, you will learn the T-SQL statements for modifying table data including UPDATE, 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.
Lessons:
- Inserting data into tables
- Modifying and deleting data
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.
