3. Understanding Database Concepts with SQL Server 2008

Before getting into SQL queries, it’s important to understand the basics of databases. Here are the key parts:

  • Databases: Organized collections of data stored electronically.
  • Tables: Structures within a database that hold data in rows and columns.
  • Fields (Columns): Represent specific attributes of the data.
  • Records (Rows): Represent a single instance of the data.
  • Primary Key: A unique identifier for each record in a table.
  • Foreign Key: A field in one table that refers to the primary key of another table, creating a link.

3.1. Data Types in SQL Server 2008

Understanding data types is key for setting up tables. Here are common data types in SQL Server 2008:

Data Type Description Example
INT Integer values 123
VARCHAR(n) Text string, where n is the maximum length 'Hello'
NVARCHAR(n) Text string with Unicode support N'你好'
DATE Date values '2023-07-01'
DATETIME Date and time values '2023-07-01 10:30:00'
DECIMAL(p, s) Number with fixed precision, where p is precision and s is scale 123.45
BIT Boolean values (0 or 1) 1

3.2. Normalization and Database Design

Database normalization is organizing data to reduce extra data and improve data integrity. Key forms include:

  1. First Normal Form (1NF): Each column has only one value.
  2. Second Normal Form (2NF): Must be in 1NF and non-key attributes depend on the primary key.
  3. Third Normal Form (3NF): Must be in 2NF and non-key attributes are not linked to each other.

Good database design using normalization makes sure data is consistent and efficient.

4. Important SQL Commands for New Users

SQL (Structured Query Language) is used to work with databases. Here are important SQL commands everyone should know:

4.1. Data Definition Language (DDL)

DDL commands define the database structure.

  • CREATE: Makes database objects (like tables).
CREATE DATABASE MyDatabase;
CREATE TABLE Employees (
ID INT PRIMARY KEY,
FirstName VARCHAR(50),
LastName VARCHAR(50)
);
  • ALTER: Changes database objects.
ALTER TABLE Employees
ADD COLUMN Email VARCHAR(100);
  • DROP: Deletes database objects.
DROP TABLE Employees;
DROP DATABASE MyDatabase;

4.2. Data Manipulation Language (DML)

DML commands change data in the database.

  • SELECT: Gets data from tables.
SELECT FirstName, LastName
FROM Employees;
  • INSERT: Adds data to a table.
INSERT INTO Employees (ID, FirstName, LastName)
VALUES (1, 'John', 'Doe');
  • UPDATE: Changes data in a table.
UPDATE Employees
SET Email = '[email protected]'
WHERE ID = 1;
  • DELETE: Removes data from a table.
DELETE FROM Employees
WHERE ID = 1;

4.3. Data Control Language (DCL)

DCL commands control database access.

  • GRANT: Gives rights to users.
GRANT SELECT, INSERT
ON Employees TO User1;
  • REVOKE: Takes away rights from users.
REVOKE SELECT, INSERT
ON Employees FROM User1;

5. Writing Simple SQL Queries in SQL Server 2008

Writing good SQL queries is key for getting useful data. Let’s look at writing simple queries with examples.

5.1. SELECT Statement

The SELECT statement gets data.

  • Selecting All Columns:
SELECT *
FROM Employees;
  • Selecting Specific Columns:
SELECT FirstName, LastName, Email
FROM Employees;
  • Using Aliases:
SELECT FirstName AS GivenName, LastName AS Surname
FROM Employees;

5.2. WHERE Clause

The WHERE clause filters results based on conditions.

  • Basic Filtering:
SELECT *
FROM Employees
WHERE LastName = 'Doe';
  • Using Comparison Operators:
SELECT *
FROM Employees
WHERE ID > 10;
  • Using Logical Operators (AND, OR, NOT):
SELECT *
FROM Employees
WHERE LastName = 'Doe' AND ID > 5;

SELECT *
FROM Employees
WHERE LastName = 'Doe' OR FirstName = 'Jane';

5.3. ORDER BY Clause

The ORDER BY clause sorts the results.

  • Ascending Order:
SELECT *
FROM Employees
ORDER BY LastName ASC;
  • Descending Order:
SELECT *
FROM Employees
ORDER BY LastName DESC;
  • Sorting by Multiple Columns:
SELECT *
FROM Employees
ORDER BY LastName ASC, FirstName ASC;

5.4. GROUP BY Clause

The GROUP BY clause groups rows with the same values.

  • Basic Grouping:
SELECT Department, COUNT(*) AS NumberOfEmployees
FROM Employees
GROUP BY Department;
  • Using Aggregate Functions:
SELECT Department, AVG(Salary) AS AverageSalary
FROM Employees
GROUP BY Department;

5.5. HAVING Clause

The HAVING clause filters groups based on conditions.

  • Filtering Groups:
SELECT Department, COUNT(*) AS NumberOfEmployees
FROM Employees
GROUP BY Department
HAVING COUNT(*) > 10;

6. Advanced SQL Concepts in SQL Server 2008

After mastering the basics, explore these advanced concepts for better data management.

6.1. Joins

Joins combine rows from two or more tables.

  • INNER JOIN: Returns rows that match in both tables.
SELECT Employees.FirstName, Departments.DepartmentName
FROM Employees
INNER JOIN Departments
ON Employees.DepartmentID = Departments.DepartmentID;
  • LEFT JOIN (LEFT OUTER JOIN): Returns all rows from the left table.
SELECT Employees.FirstName, Departments.DepartmentName
FROM Employees
LEFT JOIN Departments
ON Employees.DepartmentID = Departments.DepartmentID;
  • RIGHT JOIN (RIGHT OUTER JOIN): Returns all rows from the right table.
SELECT Employees.FirstName, Departments.DepartmentName
FROM Employees
RIGHT JOIN Departments
ON Employees.DepartmentID = Departments.DepartmentID;
  • FULL OUTER JOIN: Returns all rows when there is a match in either table.
SELECT Employees.FirstName, Departments.DepartmentName
FROM Employees
FULL OUTER JOIN Departments
ON Employees.DepartmentID = Departments.DepartmentID;

6.2. Subqueries

A subquery is a query inside another query.

  • Subquery in WHERE Clause:
SELECT *
FROM Employees
WHERE DepartmentID IN (SELECT DepartmentID FROM Departments WHERE Location = 'New York');
  • Subquery in SELECT Clause:
SELECT FirstName, LastName, (SELECT AVG(Salary) FROM Employees) AS AverageSalary
FROM Employees;
  • Correlated Subquery:
SELECT FirstName, LastName
FROM Employees E1
WHERE Salary > (SELECT AVG(Salary) FROM Employees E2 WHERE E1.DepartmentID = E2.DepartmentID);

6.3. Common Table Expressions (CTEs)

CTEs are temporary named result sets.

  • Basic CTE:
WITH AverageSalaries AS (
SELECT DepartmentID, AVG(Salary) AS AverageSalary
FROM Employees
GROUP BY DepartmentID
)
SELECT Employees.FirstName, AverageSalaries.AverageSalary
FROM Employees
INNER JOIN AverageSalaries
ON Employees.DepartmentID = AverageSalaries.DepartmentID;
  • Recursive CTE:
WITH EmployeeHierarchy AS (
SELECT ID, FirstName, LastName, ManagerID
FROM Employees
WHERE ManagerID IS NULL
UNION ALL
SELECT E.ID, E.FirstName, E.LastName, E.ManagerID
FROM Employees E
INNER JOIN EmployeeHierarchy EH
ON E.ManagerID = EH.ID
)
SELECT *
FROM EmployeeHierarchy;

6.4. Window Functions

Window functions calculate across table rows related to the current row.

  • ROW_NUMBER():
SELECT FirstName, LastName, Salary,
ROW_NUMBER() OVER (ORDER BY Salary DESC) AS RowNum
FROM Employees;
  • RANK():
SELECT FirstName, LastName, Salary,
RANK() OVER (ORDER BY Salary DESC) AS Rank
FROM Employees;
  • DENSE_RANK():
SELECT FirstName, LastName, Salary,
DENSE_RANK() OVER (ORDER BY Salary DESC) AS DenseRank
FROM Employees;
  • NTILE():
SELECT FirstName, LastName, Salary,
NTILE(4) OVER (ORDER BY Salary DESC) AS Quartile
FROM Employees;
  • LAG() and LEAD():
SELECT FirstName, LastName, Salary,
LAG(Salary, 1, 0) OVER (ORDER BY Salary) AS PreviousSalary,
LEAD(Salary, 1, 0) OVER (ORDER BY Salary) AS NextSalary
FROM Employees;

7. Stored Procedures, Functions, and Triggers

Improve your database with stored procedures, functions, and triggers.

7.1. Stored Procedures

Stored procedures are saved SQL statements.

CREATE PROCEDURE GetEmployeesByDepartment (@DepartmentID INT)
AS
BEGIN
SELECT *
FROM Employees
WHERE DepartmentID = @DepartmentID;
END;
  • Executing a Stored Procedure:
EXEC GetEmployeesByDepartment @DepartmentID = 1;
  • Modifying a Stored Procedure:
ALTER PROCEDURE GetEmployeesByDepartment (@DepartmentID INT)
AS
BEGIN
SELECT ID, FirstName, LastName
FROM Employees
WHERE DepartmentID = @DepartmentID;
END;
  • Deleting a Stored Procedure:
DROP PROCEDURE GetEmployeesByDepartment;

7.2. Functions

Functions take parameters and return a result.

  • Creating a Scalar Function:
CREATE FUNCTION CalculateTax (@Salary DECIMAL(10, 2))
RETURNS DECIMAL(10, 2)
AS
BEGIN
DECLARE @TaxRate DECIMAL(4, 2) = 0.20;
DECLARE @TaxAmount DECIMAL(10, 2);
SET @TaxAmount = @Salary * @TaxRate;
RETURN @TaxAmount;
END;
  • Using a Scalar Function:
SELECT FirstName, LastName, Salary, dbo.CalculateTax(Salary) AS TaxAmount
FROM Employees;
  • Creating a Table-Valued Function:
CREATE FUNCTION GetEmployeesBySalaryRange (@MinSalary DECIMAL(10, 2), @MaxSalary DECIMAL(10, 2))
RETURNS TABLE
AS
RETURN (
SELECT ID, FirstName, LastName, Salary
FROM Employees
WHERE Salary BETWEEN @MinSalary AND @MaxSalary
);
  • Using a Table-Valued Function:
SELECT *
FROM dbo.GetEmployeesBySalaryRange(50000, 70000);
  • Modifying a Function:
ALTER FUNCTION CalculateTax (@Salary DECIMAL(10, 2))
RETURNS DECIMAL(10, 2)
AS
BEGIN
DECLARE @TaxRate DECIMAL(4, 2) = 0.22;
DECLARE @TaxAmount DECIMAL(10, 2);
SET @TaxAmount = @Salary * @TaxRate;
RETURN @TaxAmount;
END;
  • Deleting a Function:
DROP FUNCTION CalculateTax;

7.3. Triggers

Triggers run automatically in response to events on a table.

  • Creating an INSERT Trigger:
CREATE TRIGGER AuditNewEmployee
ON Employees
AFTER INSERT
AS
BEGIN
INSERT INTO EmployeeAudit (EmployeeID, AuditAction, AuditDate)
SELECT ID, 'INSERTED', GETDATE()
FROM inserted;
END;
  • Creating an UPDATE Trigger:
CREATE TRIGGER AuditUpdatedEmployee
ON Employees
AFTER UPDATE
AS
BEGIN
INSERT INTO EmployeeAudit (EmployeeID, AuditAction, AuditDate)
SELECT ID, 'UPDATED', GETDATE()
FROM inserted;
END;
  • Creating a DELETE Trigger:
CREATE TRIGGER AuditDeletedEmployee
ON Employees
AFTER DELETE
AS
BEGIN
INSERT INTO EmployeeAudit (EmployeeID, AuditAction, AuditDate)
SELECT ID, 'DELETED', GETDATE()
FROM deleted;
END;
  • Modifying a Trigger:
ALTER TRIGGER AuditNewEmployee
ON Employees
AFTER INSERT
AS
BEGIN
INSERT INTO EmployeeAudit (EmployeeID, AuditAction, AuditDate, AdditionalInfo)
SELECT ID, 'INSERTED', GETDATE(), 'New employee added'
FROM inserted;
END;
  • Disabling a Trigger:
DISABLE TRIGGER AuditNewEmployee
ON Employees;
  • Enabling a Trigger:
ENABLE TRIGGER AuditNewEmployee
ON Employees;
