Overview

About this course
This course provides students with the technical skills required to write basic Transact-SQL queries for Microsoft SQL Server 2014. This course is the foundation for all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. This course helps people prepare for exam 70-461.

Audience profile
This course is intended for Database Administrators, Database Developers, and Business Intelligence professionals. The course will very likely be well attended by SQL power users who aren’t necessarily database-focused or plan on taking the exam; namely, report writers, business analysts and client application developers.

At course completion
After completing this course, students will be able to:

  • Describe the basic architecture and concepts of Microsoft SQL Server 2014.
  • Understand the similarities and differences between Transact-SQL and other computer languages.
  • Write SELECT queries
  • Query multiple tables
  • Sort and filter data
  • Describe the use of data types in SQL Server
  • Modify data using Transact-SQL
  • Use built-in functions
  • Group and aggregate data
  • Use sub-queries
  • Use table expressions
  • Use set operators
  • Use window ranking, offset and aggregate functions
  • Implement pivoting and grouping sets
  • Execute stored procedures
  • Program with T-SQL
  • Implement error handling
  • Implement transactions

Pre-requisites
Before attending this course, students must have:

  • Working knowledge of relational databases.
  • Basic knowledge of the Microsoft Windows operating system and its core functionality.

Course Outline

  • Module 1: Introduction to Microsoft SQL Server 2014
    This module introduces the SQL Server platform and major tools. It discusses editions, versions, tools used to query, documentation sources, and the logical structure of databases.
  • Module 2: Introduction to T-SQL Querying
    This module introduces Transact SQL as the primary querying language of SQL Server. It discusses the basic structure of T-SQL queries, the logical flow of a SELECT statement, and introduces concepts such as predicates and set-based operations.
  • Module 3: Writing SELECT Queries
    This module introduces the fundamentals of the SELECT statement, focusing on queries against a single table.
  • Module 4: Querying Multiple Tables
    This module explains how to write queries which combine data from multiple sources in SQL Server. The module introduces the use of JOINs in T-SQL queries as a mechanism for retrieving data from multiple tables.
  • Module 5: Sorting and Filtering Data
    This module explains how to enhance queries to limit the rows they return, and to control the order in which the rows are displayed. The module also discusses how to resolve missing and unknown results.
  • Module 6: Working with SQL Server 2014 Data Types
    This module explains the data types SQL Server uses to store data. It introduces the many types of numeric and special-use data types. It also explains conversions between data types, and the importance of type precedence.
  • Module 7: Using DML to Modify Data
    This module describes the use of Transact-SQL Data Manipulation Language to perform inserts, updates, and deletes to your data.
  • Module 8: Using Built-In Functions
    This module introduces the use of functions that are built in to SQL Server Denali, and will discuss some common usages including data type conversion, testing for logical results and nullability.
  • Module 9: Grouping and Aggregating Data
    This module introduces methods for grouping data within a query, aggregating the grouped data and filtering groups with HAVING. The module is designed to help the student grasp why a SELECT clause has restrictions placed upon column naming in the GROUP BY clause as well as which columns may be listed in the SELECT clause.
  • Module 10: Using Subqueries
    This module will introduce the use of subqueries in various parts of a SELECT statement. It will include the use of scalar and multi-result subqueries, and the use of the IN and EXISTS operators.
  • Module 11: Using Table Expressions
    This module introduces T-SQL expressions which return a valid relational table, typically for further use in the query. The module discusses views, derived tables, common table expressions and inline table-valued functions.
  • Module 12: Using Set Operators
    This module introduces Microsoft SharePoint Server as a platform for BI, and then focuses on building BI dashboards and scorecards with PerformancePoint Services.
  • Module 13: Using Window Ranking, Offset, and Aggregate Functions
    This module introduces window functions including ranking, aggregate and offset functions. Much of this functionality is new to SQL Server 2012. It will cover the use of T-SQL functions such as ROW_NUMBER, RANK, DENSE_RANK, NTILE, LAG, LEAD, FIRST_VALUE and LAST_VALUE to perform calculations against a set, or window, of rows.
  • Module 14: Pivoting and Grouping Sets
    This module discusses techniques for pivoting data in T-SQL as well to introduce the fundamentals of the GROUPING SETS clause. It will also cover the use of GROUP BY ROLLUP and GROUP BY CUBE syntax in SQL Server.
  • Module 15: Executing Stored Procedures
    This module introduces the use of existing stored procedures in a T-SQL querying environment. It discusses the use of EXECUTE, how to pass input and output parameters to a procedure, and how to invoke system stored procedures.
  • Module 16: Programming with T-SQL
    This module provides a basic introduction to T-SQL programming concepts and objects. It discusses batches, variables, control of flow elements such as loops and conditionals, how to create and execute dynamic SQL statements, and how to use synonyms.
  • Module 17: Implementing Error Handling
    This module introduces the use of error handlers in T-SQL code. It will introduce the difference between compile errors and run-time errors, and will cover how errors affect batches. The module will also cover how to control error handling using TRY/CATCH blocks, the use of the ERROR class of functions, and the use of the new THROW statement.
  • Module 18: Implementing Transactions
    This module introduces the concepts of transaction management in SQL Server. It will provide a high-level overview of transaction properties, cover the basics of marking transactions with BEGIN, COMMIT and ROLLBACK.
  • Module 19: Improving Query Performance
    This module presents several key guidelines for writing well-performing queries, as well as ways to monitor the execution of your queries and their impact on Microsoft SQL Server.
  • Module 20: Querying SQL Server Metadata
    SQL Server provides access to structured metadata by using a variety of mechanisms, such as system catalog views, system functions, dynamic management objects, and system stored procedures. In this module, you will learn how to write queries to return system metadata using these mechanisms.
