Introduction
Microsoft SQL Server 2012 T-SQL Fundamentals is a comprehensive course that teaches the basics of Transact-SQL, the language used to manage and manipulate data in Microsoft SQL Server. This course is designed for beginners who have little or no experience with SQL Server and want to learn how to use it to store, query, and manipulate data.
The Importance of T-SQL Fundamentals
T-SQL (Transact-SQL) is an essential tool for anyone who wants to work with SQL Server. It is the language used to create and manage databases, tables, and other objects in SQL Server. By learning T-SQL fundamentals, you will be able to write queries, insert, update, and delete data, and perform basic database management tasks. This knowledge will be invaluable if you want to pursue a career in database administration, data analysis or software development.
Getting Started with SQL Server Management Studio
The first step in learning T-SQL is to get familiar with SQL Server Management Studio (SSMS). This is a powerful tool that allows you to connect to SQL Server, create and manage databases, and write queries. In this section, we will walk you through the process of installing and configuring SSMS and show you how to create a new database and table.
Installing and Configuring SQL Server Management Studio
Before you can start using SSMS, you need to install it on your computer. You can download the latest version of SSMS from the Microsoft website. Once you have installed SSMS, you need to configure it to connect to your SQL Server instance. This typically involves specifying the server name, authentication mode, and login credentials.
Creating a New Database
Once you have connected to your SQL Server instance, you can create a new database by right-clicking on the Databases folder and selecting New Database. You will be prompted to enter a name for your database, as well as other options like the initial size and file location.
Creating a New Table
After you have created a new database, you can create a new table to store data. To do this, right-click on the Tables folder and select New Table. This will open a new window where you can define the columns and data types for your table. Once you have defined the schema for your table, you can start inserting data into it.
Basic Querying with T-SQL
The most common use for T-SQL is to write queries that retrieve data from a database. In this section, we will introduce you to some basic T-SQL commands and show you how to write simple queries to retrieve data from a table.
Select Statements
The SELECT statement is the most basic T-SQL command used to retrieve data from a table. It allows you to specify which columns you want to retrieve and which table you want to retrieve them from. For example, the following query retrieves all columns from the Customers table:
Where Clauses
The WHERE clause is used to filter the results of a query based on a specific condition. For example, the following query retrieves only the customers whose last name is Smith:
Order By Clauses
The ORDER BY clause is used to sort the results of a query in ascending or descending order. For example, the following query retrieves all the customers in the Customers table, sorted by last name in ascending order:
Conclusion
In conclusion, Microsoft SQL Server 2012 T-SQL Fundamentals is an excellent course for anyone who wants to learn how to use SQL Server to store, query, and manipulate data. By learning the basics of T-SQL, you will be able to write queries, insert, update, and delete data, and perform basic database management tasks. Whether you want to pursue a career in database administration, data analysis or software development, this knowledge will be invaluable.

Understanding SQL Server 2012 T-SQL Language Fundamentals
Microsoft SQL Server 2012 is a powerful relational database management system that uses the Transact-SQL (T-SQL) language for querying and manipulating data. To effectively utilize the power of SQL Server, it is essential to understand the fundamentals of T-SQL. This involves learning the basic syntax, keywords, and constructs of T-SQL, such as SELECT, FROM, WHERE, JOIN, and GROUP BY. Understanding the data types, including numeric, string, date/time, and binary data types, is also crucial. It is also essential to know how to create and modify databases, tables, and other database objects using T-SQL.Navigating SQL Server Management Studio
SQL Server Management Studio (SSMS) is a tool used to manage and administer SQL Server databases. To navigate SSMS, you need to know how to create, modify, and delete databases, tables, views, stored procedures, and user-defined functions. You should also be familiar with the Object Explorer, which allows you to browse and manipulate database objects, and the Query Editor, which enables you to write and execute T-SQL queries.Creating and Editing Tables
Tables are the fundamental building blocks of any relational database. To create and edit tables in SQL Server, you need to define the structure of the table, including its columns, data types, and constraints. You can also add indexes and triggers to improve performance and maintain data integrity. It is important to follow best practices when defining table structures, such as using appropriate column names, setting default values, and avoiding redundant data.Working with Data Types
Data types are an integral part of T-SQL programming. They define the type of data that can be stored in a column or variable. SQL Server supports a wide range of data types, including numeric, string, date/time, and binary data types. Understanding the different data types and how they are used is essential to writing efficient and effective queries.Writing Basic T-SQL Queries
At its core, T-SQL is a query language used to retrieve data from SQL Server databases. To become proficient with T-SQL, you need to learn how to write basic queries that select, filter, and sort data. This involves using the SELECT, FROM, WHERE, and ORDER BY clauses, as well as aggregate functions, such as SUM, AVG, COUNT, and MAX. You should also know how to use Boolean operators, such as AND, OR, and NOT, to create complex conditions.Using Functions and Operators
T-SQL provides a wide range of built-in functions and operators that enable you to manipulate, aggregate, and transform data. For example, you can use mathematical functions, such as ABS, ROUND, and CEILING, to perform calculations on numeric data. You can also use string functions, such as LEN, SUBSTRING, and REPLACE, to manipulate text data. Knowing how to use these functions and operators is essential to writing complex and efficient queries.Working with Views and Stored Procedures
Views and stored procedures are powerful tools in SQL Server that enable you to encapsulate complex queries and business logic into reusable code. A view is a virtual table that represents the result set of a select statement, while a stored procedure is a precompiled set of SQL statements that can be executed with parameters. Learning how to create and use views and stored procedures is an important step towards mastering T-SQL.Managing Transactions and Concurrency
Transactions and concurrency are critical aspects of SQL Server performance and reliability. Transactions ensure that a group of related SQL statements are executed as a single unit of work, either all succeeding or all failing. Concurrency controls ensure that multiple users can access and modify data concurrently without creating conflicts or inconsistencies. Understanding how to manage transactions and handle concurrency issues is essential for building robust and scalable applications.Best Practices for Writing T-SQL Code
Like any programming language, there are best practices for writing T-SQL code that improve performance, readability, and maintainability. Some of these practices include using meaningful variable names, commenting your code, avoiding unnecessary subqueries, and using set-based operations instead of cursors. Learning and applying these best practices will make your code more effective and efficient.Advanced T-SQL Concepts
Once you have mastered the fundamentals of T-SQL, you can move on to more advanced concepts, such as window functions, common table expressions, and dynamic SQL. Window functions enable you to perform complex calculations over a group of rows, while common table expressions provide a way to define temporary result sets that can be referenced multiple times in a query. Dynamic SQL allows you to construct and execute SQL statements at runtime, enabling you to build even more sophisticated and powerful applications.The Fundamentals of Microsoft SQL Server 2012 T-SQL
