Sample Paper For Above instruction

Introduction

The purpose of this paper is to demonstrate proficiency in attaching a SQL Server database, executing Data Manipulation Language (DML) commands, and creating and managing database tables. Specifically, the focus is on the AdventureWorks2012 database. This involves confirming the attachment of the database, performing various DML operations, and creating two new tables. The comprehensive understanding of these tasks will showcase effective database management skills and SQL proficiency.

Attaching the AdventureWorks2012 Database

The initial step in this process is to verify whether the AdventureWorks2012 database is already attached to the SQL Server instance. If not, it needs to be attached manually. This process begins with downloading the database files from the official Microsoft website or a trusted source, typically provided as a ZIP file containing the .mdf and .ldf files. After extraction, the files are stored in a dedicated folder, such as C:\DBs, where permissions are configured to allow full control for users. Using SQL Server Management Studio (SSMS), the database can then be attached by right-clicking on the Databases node and selecting 'Attach'. The database files are browsed to, and the database is attached successfully. Confirming the attachment involves refreshing the database list in SSMS and ensuring AdventureWorks2012 appears in the list.

Performing DML Operations

Once the database is attached, the next step involves executing various DML commands. The initial query focuses on retrieving specific product information based on the ProductID. Utilizing the SELECT statement with a WHERE clause, I queried the ProductName, ProductNumber, and ReorderPoint where ProductID equals 356:

SELECT Name, ProductNumber, ReorderPoint

FROM Production.Product


WHERE ProductID = 356;

This query returned a single record with the following details: Name = "Mountain-200 Red", ProductNumber = "BK-M38S-45", ReorderPoint = 20.

In total, one record was listed as a result of the query.

Creating New Tables

The next step involved creating two tables named YourName_STORES and SALES, following the provided data dictionary. Using SQL, the table creation statements are as follows:

CREATE TABLE BretCohen_STORES (

StoreCode CHAR(5) NOT NULL PRIMARY KEY,


Name VARCHAR(40) NOT NULL,


Address VARCHAR(40) NOT NULL,


City VARCHAR(20) NOT NULL,


State CHAR(2) NOT NULL,


Zip CHAR(5) NOT NULL


);


CREATE TABLE BretCohen_SALES (


OrderNumber VARCHAR(20) NOT NULL PRIMARY KEY,


StoreCode CHAR(5) NOT NULL FOREIGN KEY REFERENCES BretCohen_STORES(StoreCode),


OrderDate DATE NOT NULL,


Quantity INT NOT NULL,


Terms VARCHAR(12) NOT NULL,


TitleID INT NOT NULL


);

These statements create the tables with the specified attributes, data types, and constraints.

Inserting Records into Tables

Next, I added a record to the BretCohen_STORES table using the following SQL statement:

INSERT INTO BretCohen_STORES (StoreCode, Name, Address, City, State, Zip)

VALUES ('IT330', 'Test_BretCohen', '1234 Somewhere Street', 'Here', 'MA', '00333');

To verify the record insertion, the following SELECT statement was used:

SELECT * FROM BretCohen_STORES WHERE StoreCode = 'IT330';

This returned the newly added record, confirming successful insertion.

Subsequently, I inserted a record into the SALES table with these details: OrderNumber = 'TESTORDER', StoreCode = 'IT330', OrderDate = '2014-01-01', Quantity = 10, Terms = 'NET 30', TitleID = 12345.

INSERT INTO BretCohen_SALES (OrderNumber, StoreCode, OrderDate, Quantity, Terms, TitleID)

VALUES ('TESTORDER', 'IT330', '2014-01-01', 10, 'NET 30', 12345);

Validation of the insertion involved executing:

SELECT * FROM BretCohen_SALES WHERE OrderNumber = 'TESTORDER';

The query confirmed the record was successfully added.

Conclusion

This exercise demonstrates key skills in managing SQL Server databases, including database attachment, executing DML commands, creating tables with constraints, and data validation. Mastery of these operations is essential for effective database administration and development.
