• Set the SQL Server instance to listen on the desired port, such as port 1433.

It is also important to note that SQL Server Management Studio (SSMS) is a separate tool that can be used to manage and administer SQL Server instances. SSMS provides a graphical user interface for managing databases, executing queries, and monitoring performance.

Basic Operations in SQL Server 2022 Express

Once you have installed and configured SQL Server 2022 Express, you can start performing basic operations, such as creating databases, tables, and relationships. Here are some examples:

Creating a Database

To create a database in SQL Server 2022 Express, you can use the following Transact-SQL (T-SQL) statement:

CREATE DATABASE MyDatabase;

This statement creates a new database named "MyDatabase" in the SQL Server instance.

Creating a Table

To create a table in a database, you can use the following T-SQL statement:

CREATE TABLE MyTable (ID INT PRIMARY KEY, Name VARCHAR(50));

This statement creates a new table named "MyTable" in the "MyDatabase" database, with two columns: "ID" and "Name".

Inserting Data

To insert data into a table, you can use the following T-SQL statement:

INSERT INTO MyTable (ID, Name) VALUES (1, 'John Doe');

This statement inserts a new row into the "MyTable" table, with the values "1" for the "ID" column and "John Doe" for the "Name" column.

Security Considerations

SQL Server 2022 Express provides various security features to protect your data, such as authentication modes, encryption, and access control. Here are some security considerations to keep in mind:

• Use Windows Authentication to authenticate users and provide access to databases.
• Use encryption to protect sensitive data, such as credit card numbers or personal identifiable information.
• Use access control to restrict access to databases and tables, based on user roles and permissions.

Backup and Recovery

It is essential to perform regular backups of your databases to ensure data integrity and availability. Here are some backup and recovery considerations:

• Use the SQL Server Management Studio to create and manage backup plans.
• Use the BACKUP T-SQL statement to create full, differential, and transaction log backups.
• Use the RESTORE T-SQL statement to recover databases from backups.
