Example Usage

This example isn't about *performing* SQL Server tasks, but rather *demonstrating* the knowledge required for certification. A certification exam would contain many more complex questions and scenarios. This is a simplified example to illustrate the kind of knowledge tested. ```sql -- Example query demonstrating understanding of data types and constraints. CREATE TABLE Customers ( CustomerID INT PRIMARY KEY, FirstName VARCHAR(50) NOT NULL, LastName VARCHAR(50) NOT NULL, Email VARCHAR(100) UNIQUE ); -- Example query demonstrating understanding of joins. SELECT c.CustomerID, c.FirstName, o.OrderID FROM Customers c JOIN Orders o ON c.CustomerID = o.CustomerID; ```

Common Mistakes

Assuming that one certification level is sufficient for all roles.
Not studying the specific topics covered in the certification exam.
Relying solely on theoretical knowledge without practicing hands-on exercises.
Failing to understand the practical application of SQL Server concepts in real-world scenarios.
