SQL Server Updates – A Comprehensive Guide for Dev

Hello, Dev! Welcome to our comprehensive guide on SQL Server updates. In today’s fast-paced world, it is essential to keep your server up-to-date for better performance and security. This guide will take you through everything you need to know about SQL Server updates starting from scratch. So, let’s get started!

What is SQL Server and Why is it Important to Keep it Updated?

If you are new to SQL Server, it is a relational database management system (RDBMS) that helps you create, manage, and store your data effectively. It is widely used across various industries, such as banking, healthcare, and e-commerce, to store and retrieve data.

Now, you must be wondering why it is crucial to keep your SQL Server updated. Well, updating your SQL Server ensures that you have access to the latest features, security patches, bug fixes, and performance improvements. This helps your server run smoothly, reduces the risk of cyber-attacks, and enhances your user experience.

Understanding SQL Server Update Types

There are three types of SQL Server updates: Cumulative Updates (CU), Service Packs (SP), and Major Updates (MU). Let us look at each of them in detail.

Cumulative Updates (CU)

Cumulative Updates are the most frequent updates released by Microsoft. These updates contain only the latest bug fixes and security patches. They do not add new features to the SQL Server. They are released every month, and it is recommended to apply them regularly for better performance and security.

However, you should be cautious while applying these updates as they might cause compatibility issues with some applications. It is advisable to test the CU on a test server before applying it to the production environment.

Service Packs (SP)

Service Packs are relatively less frequent than Cumulative Updates. They contain all the bug fixes, security patches, and new features released in the previous CUs. They are released every year or two, depending on the SQL Server’s version. Service Packs also undergo extensive testing before release to avoid any compatibility issues.

Major Updates (MU)

Major Updates include significant changes in the SQL Server architecture, along with new features and bug fixes. These updates are released every two to three years and require a complete installation of SQL Server. Unlike CUs and SPs, Major Updates are not backward compatible. You need to migrate your databases from the previous version to the new one.

SQL Server Update Process

Now that you know the types of SQL Server updates let us move to the update process. The update process involves four steps:

Step 1: Backup your Databases

Before starting the update process, it is crucial to take a backup of all your databases. This ensures that you have a restore point in case anything goes wrong during the update process.

Step 2: Download the Latest Updates

You can download the latest updates from the Microsoft Download Center or Windows Update. Make sure to download the update that is compatible with your SQL Server version.

Step 3: Apply the Update

Once you have downloaded the update, run the executable file and follow the instructions. The update process might take some time, depending on the size of your SQL Server database. Do not interrupt the update process, and wait till it is completed.

Step 4: Verify the Update

After applying the update, it is crucial to verify if the update has been successful. You can verify the update by checking the SQL Server version or running a test application.

SQL Server Update Best Practices

Here are some best practices that you should follow while updating your SQL Server:

1. Always Backup Your Databases

As mentioned earlier, take a backup of all your databases before updating your SQL Server.

2. Test the Updates on a Test Server

Test the updates on a test server before applying them to the production environment. This will avoid any compatibility issues.

3. Read the Release Notes Carefully

Read the release notes carefully before applying the update. They contain important information about the updates, such as known issues, bug fixes, and new features.

4. Schedule the Updates During Off-Hours

Schedule the updates during off-hours to avoid any disruption in your SQL Server operations.
