Lesson 1: Creating Database Objects
- Creating a database (Tutorial)
- Creating a table (Tutorial)
- Inserting and updating data in a table (Tutorial)
- Reading data in a table (Tutorial)
- Summary: Creating database objects
Lesson 2: Configuring Permissions on Database Objects
- Creating a login

Requirements

Any edition of SQL Server
SQL Server Management Studio or Management Studio Express
Internet Explorer 6 or later (or equivalent)

Creating a Database (Procedure)

Use the CREATE DATABASE statement
The database name is required
Optional parameters exist for disk location
SQL Server uses default values when no optional parameters are provided

Creating a Table (Procedure)

Provide a table name and column definitions
Primary keys should be used for uniqueness
Data types and NULL values (allowing empty fields) must be specified

Inserting and Updating Data (Procedure)

INSERT statement to insert data into a table
UPDATE statement to modify existing data
WHERE clause for specific row updates

Reading Data (Procedure)

Use the SELECT statement for data retrieval
The syntax can include columns; all columns; or a WHERE clause for filtering

Creating Views and Stored Procedures

Views are stored SELECT statements
Stored procedures are sets of Transact-SQL statements
Stored procedures can accept inputs and outputs, managing flow.

Granting Access to Objects

Use the GRANT statement to give users permissions (e.g., execute stored procedures)
Executing (or running) a stored procedure requires EXECUTE permission.
To remove permissions use REVOKE

Deleting Objects

Use DROP statements to remove procedures, views, tables, and databases
