Introduction

Microsoft SQL Server 2012 T-SQL Fundamentals is an essential tool for developers and database administrators who work with SQL Server. This book provides an in-depth understanding of the Transact-SQL programming language and how to use it effectively to manipulate data within SQL Server. The book covers all the fundamental concepts and syntax of T-SQL, including data types, functions, operators, and more.

Data Types and Variables

The first chapter of the book introduces data types and variables in T-SQL. It explains how to declare variables, assign values to them, and use them in queries. The chapter also covers the various data types supported by SQL Server, including numeric, string, and date/time data types.

Declaring Variables

In T-SQL, variables are declared using the DECLARE statement. The syntax for declaring a variable is:

DECLARE @variable_name data_type

For example, to declare a variable called @name of type VARCHAR(50), you would use the following code:

DECLARE @name VARCHAR(50)

Assigning Values to Variables

To assign a value to a variable, you use the SET statement. The syntax for assigning a value to a variable is:

SET @variable_name = value

For example, to assign the value John to the @name variable, you would use the following code:

SET @name = 'John'

Functions

The second chapter of the book covers functions in T-SQL. Functions are pre-written code that performs specific operations on data. SQL Server provides a wide range of functions, including string, numeric, and date/time functions.

String Functions

String functions are used to manipulate character strings. Some commonly used string functions in T-SQL include:

  • LEN: returns the length of a string
  • LOWER: converts a string to lowercase
  • UPPER: converts a string to uppercase
  • SUBSTRING: returns a portion of a string

Numeric Functions

Numeric functions are used to perform mathematical operations on numeric data. Some commonly used numeric functions in T-SQL include:

  • SUM: calculates the sum of a set of values
  • AVG: calculates the average of a set of values
  • MAX: returns the maximum value in a set of values
  • MIN: returns the minimum value in a set of values

Operators

The third chapter of the book covers operators in T-SQL. Operators are used to perform operations on data, such as arithmetic, comparison, and logical operations.

Arithmetic Operators

Arithmetic operators are used to perform mathematical operations on numeric data. Some commonly used arithmetic operators in T-SQL include:

  • + (addition)
  • - (subtraction)
  • * (multiplication)
  • / (division)

Comparison Operators

Comparison operators are used to compare values in T-SQL. Some commonly used comparison operators in T-SQL include:

  • = (equal to)
  • <> (not equal to)
  • > (greater than)
  • < (less than)

Joins

The fourth chapter of the book covers joins in T-SQL. Joins are used to combine data from multiple tables in a database.

Inner Join

An inner join returns only the rows that have matching values in both tables. The syntax for an inner join is:

SELECT column1, column2, ...FROM table1INNER JOIN table2ON table1.column_name = table2.column_name;

Left Join

A left join returns all the rows from the left table and the matching rows from the right table. If there is no match in the right table, NULL values are returned. The syntax for a left join is:

SELECT column1, column2, ...FROM table1LEFT JOIN table2ON table1.column_name = table2.column_name;

Conclusion

Microsoft SQL Server 2012 T-SQL Fundamentals is an excellent resource for anyone who wants to learn T-SQL or improve their skills in working with SQL Server. The book covers all the essential concepts and syntax of T-SQL, including data types, variables, functions, operators, and joins.
