How to Patch SQL Server? Update SQL Server Patch Step by Step

Microsoft SQL Server often releases updates or packs known as SQL Server patches for its users. Now, here we have a problem parallel to it. Not all users know how to patch SQL Server database without any issues. This is not because of the complicated task. The reason is the unawareness of these packs or patches. Thus, this article will fill all the gaps by mentioning the SQL Server patch, processes, solutions, strategies, and benefits of SQL Server patching. We are all aware that Microsoft frequently provides SQL Server updates to users. The intention for this is to enhance performance, security, features, etc. All SQL Server users can get these update packs from the official Microsoft website. Users can have SQL Server patching issues if they avoid these patches. This is because Microsoft releases these updates to help users protect their databases. Ransomware, all types of SQL injection attacks, etc., cyber threats that always hover above the head can be tackled this way. Let’s begin with understanding what these patches are in detail.

Understanding SQL Server Patches in Depth

To learn how to patch SQL Server, we must know all about it. The SQL Server patches are categorized in the following parts: Cumulative Updates(CU), Service Packs(SPs), and General Distribution Releases (GDRs). Let’s now understand these patches in depth, one by one, for better understanding. What is a Cumulative Update? When a group of multiple patches & SQL Server updates comes out by Microsoft, we call it a Cumulative Update. These updates are released to fix several issues, such as security fixes or issues related to performance, security, etc. Every cumulative update fixes all the bugs and issues in the server, allowing users not to manually update or use any older CU or older SQL Server updates, as the latest one will fix the issues with the older SQL Server patches. What is a Service Pack? Even though Service packs were discontinued with SQL Server 2016 and the newer versions use cumulative updates and GDRs, let’s still take a look at what SPs are. A service pack was nothing but a group of multiple Cumulative Updates. The service packs combined different cumulative updates and enhanced features in a single package. However, the SPs ended after SQL Server 2016, and later received only GDRs and CUs. What is a General Distribution Release? When we get an update to fix security issues, it comes with a GDR, or general distribution release. These are SQL Server patches and updates that are directly aimed at addressing security issues in the database. The General Distribution Release is not used for minor issues; instead, they are used for more critical issues in the database.

The Strategy to Update SQL Server Patches Without Issues

Now that we are well aware of the SQL Server patches, it’s time to make a proper plan or strategy on how to patch SQL Server. Without planning the entire process, there is no way that we can get the desired results as expected. To make a clearer strategy, here we have a few points to take care of. Let’s understand these points one by one: To make a robust strategy, here we have a few points that users can work on. Let’s have a look at this:

• Check Server Vitals: Closely monitor the server, like free disk space, no pending reboot, no failed SQL Agent jobs, and DBCC CHECKDB for any severe changes. Make sure there aren’t any issues that might create hassles in the process. Proceed only after getting clearance from all concerned departments.
• Plan Patching for the Right Time: Always plan the operation when the least or no users need to operate in the server. Off-working hours are generally considered the perfect time for such operations, as the process requires a restart and validation, which can further lead to operation delays in the database.
• Check Database Dependencies: Ensure that the applications, linked servers, replication, and required third-party solutions efficiently support the new build. 
• Run Pilot Projects: Run a demo operation. Before executing the actual process step by step, cross-verify that everything is going as per the plan. 
• Prepare Disaster Recovery Plans: Be ready with the disaster recovery plans at every moment. If anything goes off the plan, quickly take action to protect the data files with minimal or no loss at all.
• Document the Process: Record the complete information, including the build number, date, and KB number, after the validation passes.

How to Patch SQL Server Step by Step?

Now, comes the real question: what is the actual process for users to learn how to update SQL Server patches? Well, as we mentioned, Microsoft offers these updates on the official website; the process is manual, too. Users can get the installer & without any solution, execute the entire procedure of SQL Server patching step by step. There are mainly three steps (four steps in some cases) that can help users get the best solution. This SQL Server updates and patching step by step starts with the prerequisites:

Prerequisites for SQL Server Patching Process

The very first step for learning how to patch SQL Server database is understanding the prerequisites. Evidently, it is always good to keep prerequisites within the SQL Server patch procedure to not skip it in any case. Go through the following prerequisites: Check Compatibility Make sure that the SQL Server patches, which are going to be installed, are compatible with the SQL Server. There are several cases in which users forget to check compatibility that & then later face complications. The compatibility of the service pack with the SQL Server version is mentioned by Microsoft. To check the SQL Server version, we have two ways. These are of SSMS or T-SQL. The SSMS Method:

1. Open the SSMS in the system.
2. Right-click on Server & Hit the Properties button.
3. The SQL Server Version is there on the general page to proceed with how to patch SQL Server process.

Also, we have the T-SQL Method to check version for updating SQL Server patches: Run Query-

SELECT @@VERSION version

Result-  Take Backups Having the latest backup of the entire database is a must before initiating the update. Learning how to update SQL Server patch becomes much easier with an upper hand like this.

Running the Service Pack Step by Step

Installation Steps:

1. Stop SQL Server Services using SQL Server Configuration Manager here.
2. Download the Service Pack, Cumulative Update, etc. from the official website.
3. Click on the installer & begin installing it on the device to launch the installation wizard for SQL Server patches.

1. Go through the license terms and conditions thoroughly & accept them.
2. Choose the desired Components to install in the system.
3. Confirm the Installation Path as desired after cross-checking.
4. Set Installation Options & verify after making required changes.
5. The operation will be completed after a while without any hassles.

Avoid SQL Server Patching Issues Post-Installation

• Restart the SQL Server Service after patch installation.
• Verify if all the SQL components are working fine or not.
• Cross-check the updated versions of SQL in SSMS.
• Run some queries to check the usual operation of the database.

This way, users can easily tackle errors after the SQL patching operation. Moreover, now it’s time to move ahead with the advanced automated solution for how to patch SQL Server and to fix major related errors to SQL patching and updates for sure.

Benefits of Learning How to Update SQL Server Patches

There are plenty of benefits of learning how to patch SQL Server that users need to know. There are plenty of risks associated with SQL that users can prevent with patch updates.

• Legal Compliance: Updates like this help in avoiding compliance issues. When confidential information is compromised, legal compliance issues tend to occur. This is what users can prevent with patches.
• Get Rid of Malware: The updated patches provide up-to-date security features. Therefore, users can easily get free from all kinds of threats like malware, ransomware, SQL injection, etc.
• The Latest Features: By missing patches, users can not get the updated features. Therefore, it is the best way to understand & use new features, save time & be more productive without any hassles.
• Prevent Data Theft or Loss: Data loss in SQL is not a new thing; as soon as a business faces data theft, 60 out of 100 organizations shut down forever. Patches take care of such issues.
