Study Notes
Database Creation and Management in SQL Server
- The lecture focuses on creating a database named "DB commerce" for an e-commerce project using SQL Server.
- The project will be used to store all information for the e-commerce project.
Basic Commands for Database Creation
- Basic commands related to creating the database will be covered.
- The script is written to work with the SQL language.
- The connection is established to the local host.
- A database is created as repository to store all information of the project.
Creating a Database
- The command to create a database is
Create Database <databasename>. - Example:
CREATE DATABASE DB_commerce - The creation can be verified by refreshing the databases list.
- After refreshing, the new database appears allowing tables and other elements to be added.
Using a Database
- To specify the database to use there are two methods.
- Method 1: Select the desired database from the dropdown menu in the interface.
- Method 2: Use the command
USE <databasename>. - Example:
USE DB_commerce. - Use F5 as shortcut in the bank to execute the commands.
Renaming a Database
- To rename a database, the command is
sp_renamedb 'old_name', 'new_name'. - The procedure needs the old name and the new name as parameters.
- Example
exec sp_renamedb 'DB commerce 2', 'DB commerce' - Refreshing the databases list will show the renamed database.
Deleting a Database
- To delete a database, the command is
DROP DATABASE <databasename>. - If the database is in use, it cannot be deleted.
- To prevent this, switch to another database before dropping the target.
- The databases list must be refreshed to verify the database deletion.
Conditional Deletion
- The clause
IF EXISTScan be used to conditionally drop a database. - The command is
DROP DATABASE IF EXISTS <databasename>. - This prevents errors if the database does not exist.
- The command only executes if the database exists, otherwise, it does nothing.
Preparing for the Next Lesson
- Create the bank and set everything to start utilizing for the next class.
- The next lesson will cover creating tables within the created database.
