SQL Server 2014 Zero to Hero Guide

If you want to master Microsoft SQL Server 2014 and learn how to design, build, and optimize real databases, this course takes you from beginner to advanced level step by step.
Whether you're a database developer, SQL Server DBA, or backend developer, this training covers everything you need - from tables and indexes to stored procedures and performance tuning 🔥

Why Learn SQL Server 2014? 🗄️​

Even though newer versions exist, SQL Server 2014 is still widely used in many companies and enterprise systems.
Learning it helps you:

• 📊 Build professional relational databases
• ⚡ Optimize queries for high performance
• 🔐 Manage transactions and concurrency
• 🛠️ Troubleshoot database issues
• 💼 Improve your job opportunities in database development

If you’re serious about working with enterprise data systems, SQL Server is a must.

Implementing Tables and Views 🏗️​

The course starts with the foundation: tables and views.
You’ll learn how to:

• Choose the right data types
• Apply constraints (PRIMARY KEY, FOREIGN KEY, NOT NULL)
• Create temporary tables
• Use Common Table Expressions (CTEs)
• Build views as abstraction layers

Example: Creating a Table​

CREATE TABLE Users (
    UserID INT PRIMARY KEY,
    Username NVARCHAR(100) NOT NULL,
    Email NVARCHAR(150) UNIQUE,
    CreatedAt DATETIME DEFAULT GETDATE()
);

Example: Creating a View​

CREATE VIEW ActiveUsers AS
SELECT Username, Email
FROM Users
WHERE CreatedAt IS NOT NULL;

Views help simplify complex queries and protect the underlying schema.

---

Implementing Indexes for Performance ⚡​

Indexes are critical for performance in SQL Server.
You’ll understand:

• Difference between Heap, Clustered Index, and Non-Clustered Index
• When to use filtered indexes
• Page density and maintenance
• Index optimization strategies

Example: Creating a Clustered Index​

CREATE CLUSTERED INDEX IX_Users_UserID
ON Users(UserID);

Example: Non-Clustered Index​

CREATE NONCLUSTERED INDEX IX_Users_Email
ON Users(Email);

Choosing the right index can drastically improve query performance 🚀

---

Stored Procedures and Functions 🔄​

Stored procedures are essential in enterprise SQL development.
You’ll learn:

• Execution context
• Parameters and return values
• Scalar and table-valued functions
• Best practices

Example: Stored Procedure​

CREATE PROCEDURE GetUserById
    @UserID INT
AS
BEGIN
    SELECT * FROM Users WHERE UserID = @UserID;
END;

Execute it like this:

EXEC GetUserById @UserID = 1;

Stored procedures improve security, performance, and code organization.

---

Managing Transactions and Concurrency 🔐​

This section teaches:

• What transactions are
• Isolation levels
• Error handling
• Locking and deadlocks
• Concurrency control

Example: Transaction​

BEGIN TRANSACTION;

UPDATE Users
SET Email = 'new@email.com'
WHERE UserID = 1;

COMMIT;

If something fails:

ROLLBACK;

Understanding transactions is critical for data consistency.

---

Implementing In-Memory Objects 🚀​

SQL Server 2014 introduced In-Memory OLTP features.
You’ll explore:

• Columnstore indexes
• In-memory tables
• Memory-optimized stored procedures
• Hybrid systems (disk + memory)

These features dramatically improve performance in high-load systems.

---

Query Optimization and Troubleshooting 🔎​

This part focuses on:

• Identifying slow queries
• Execution plans
• Query tuning techniques
• Performance bottlenecks
• Analyzing workload

Example: Checking Execution Plan​

SET SHOWPLAN_ALL ON;
GO
SELECT * FROM Users WHERE Email = 'test@email.com';
GO
SET SHOWPLAN_ALL OFF;

Understanding execution plans is key to becoming an advanced SQL developer.
