Executive SummaryUpdated on Apr 20, 2025

SQL Server and MySQL are key competitors in the database management system category. SQL Server appears to have the upper hand for larger, enterprise-level applications, while MySQL excels in smaller, community-driven projects due to its open-source model.

Features: SQL Server offers dynamic resource allocation, the Graphical Query Analyzer for interactive query execution, and robust OLAP services. Additionally, it includes tools like SSIS, SSRS, and SSAS for comprehensive data management. MySQL, on the other hand, provides open-source flexibility, a multi-threaded architecture, and seamless integration with web development stacks like LAMP and WAMP.

Room for Improvement: SQL Server is limited by install prerequisites and platform compatibility, primarily supporting Windows and incurring high feature costs. MySQL lacks advanced IDEs and features such as robust replication capabilities and check constraints, requiring improvements in security, scalability, and enterprise-level features.

Ease of Deployment and Customer Service: SQL Server offers extensive documentation and a strong support community, though enterprise support can be costly and response times slow. It is widely adopted in on-premise and cloud setups. MySQL benefits from its open-source community support, making it highly flexible with platform compatibility, though expert support can be more limited.

Pricing and ROI: SQL Server's pricing is premium due to licensing fees, often bundled with other Microsoft products, offering substantial ROI in enterprise environments. MySQL, free for non-commercial use, presents significant cost savings, ideal for startups and smaller projects. Enterprises with fewer financial constraints may gain higher ROI from SQL Server's extensive features, whereas budget-conscious organizations benefit from MySQL's lower entry costs.

Native encryption ensures secure data management with a simple deployment

The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.

It has eliminated all kinds of inconsistencies, and it is reliable, secure, and fast

I don't know whether SQL Server can support large organizations where the database size is more than 100 GB. It might be because of SQL Server, or it might be because of the programming of the software vendor, but a lot of people think that it is a problem with SQL Server. It can't handle a large amount of data or large data size. In terms of its usage, about 90% of our applications are running on the SQL Server database. We have around 1,600 users for our software, and all the applications are connected to the SQL Server database.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"MySQL is open-source. There are a lot of open-source communities trying to come up with their own patches, and to come up with their own features, which help MySQL develop faster than traditional databases like Oracle, which is closed source."

"The fact that it is free is what appeals to me the most."

"The solution has been very easy to scale so far."

"MySQL is an easy-to-use solution that provides stability, reliability, flexibility, performance, security, and high availability."

"The initial setup is easy."

"This specific version of this MySQL has been battle tested for a long time. Any issues are known issues and we pretty much don't have any problems when they're in production. So it's very stable."

"I like MySQL's feature that helps to automate things."

"We are completely comfortable with the database’s performance and it is a mature product. My organization was looking for an open-source database for our smaller customers like the community edition. For bigger customers, we can scale into commercial and supported editions."

More MySQL pros

"For me, the initial setup is very easy as I have years of experience with the product."

"It is integrated with Microsoft tools."

"The solution is valuable because it seamlessly extracts reports and enables the collection of information from different tables."

"Very stable relational database management system that offers ease of management, querying, and scaling. It has well-designed databases."

"Technical support is very good."

"The performance is good."

"I like that it's very easy to use, and Veeam is excellent. There are tons of experts and writers in the area now, and we don't find the same for other databases."

"I have found SQL Server easy to use."

More SQL Server pros

Cons

"MySQL's performance requires attention. For optimal performance, one should review and sometimes revise the code, particularly when using server-side scripting."

"The tool needs to improve table visualization."

"In terms of what I'd like to see in the next release, one thing that's always missing is dash boarding. There's no real BI tool for MySQL, like there is in Yellowfin and all the different tools that you get. They all have MySQL connectors, but there's no specific BI tool for MySQL. These open source projects have sprung up, but they're more general purpose."

"If it had something similar to Microsoft’s DTS engine then it would be the best database system out there."

"Rather than going in-depth about the technical features, which a technical person can directly tell, I would say that MySQL should be able to adapt to the next framework. The 5G framework means an unstructured framework. So if MySQL becomes smoother and more adaptable, it'll be easier."

"Security is a concern. MySQL could have better security features."

"It is not as powerful as SQL Server. It can be more powerful. It is not scalable and has certain limitations, which is not the case with SQL Server."

"The product is a little bit complex and it is difficult to find sufficient documentation."

More MySQL cons

"I would like to see SQL Server add the ability to write to multiple sites or support replication between multiple sites at the transaction level."

"Occasionally the performance, as good as it is, is a bit off. We sometimes experience memory spiking. If they could maybe fix that aspect of the solution, that would be quite helpful for our organization."

"It would be nice if there was a feature to search for a specific value across multiple tables. This would save a lot of time for its users."

"Indexing, as well as integration, are areas of this product that need improvement."

"The Task Scheduler has a lot of shortcomings. This could be improved quite a bit."

"As SQL server could not support the number of connections we desired, we were forced to go with Oracle."

"The solution’s pricing and integration could be improved."

"The pricing could be more affordable."

More SQL Server cons

Pricing and Cost Advice

"It's free."

"The pricing is not much expensive, it's cheap."

"There is a license needed for this solution."

"It is an open source platform."

"MySQL is released under an open-source license, so you have nothing to pay to use it."

"MySQL is free."

"The tool is open source."

"The price of the solution is good because we have a good partner."

More MySQL pricing and cost advice

"SQL Server is expensive if you use the advanced SQL version, but if you use the standard version, it's not expensive."

"It has the easiest licensing."

"The price of SQL Server could be reduced, the license is expensive. We have an annual subscription."

"The price of the solution is very expensive. If I went with the cloud version of SQL a license would cost me approximately 11,000 Riyals per month."

"The cost is high and because it's an expensive product, we are in the process of moving towards open-source solutions."

"I believe the licensing to be on an annual basis."

"The price of the solution could be reduced, it is expensive."

"SQL Server has the best licensing price."

Oracle

SQL Server is a relational database management system (RDBMS) by Microsoft. The product's main purposes are to store data and retrieve it as requested by other software applications - on the same computer or on another computer across a shared network. The solution is built on top of Structured Query Language (SQL), which is a standardized programming language used for relational database management.

The product is tied to Transact-SQL (T-SQL), which is an implementation of SQL from Microsoft that adds several proprietary programming extensions to the standard language. SQL Server is built similarly to other RDBMS products, as its structure is a row-based table that connects related data elements in different tables to one another. One of its most important components is the SQL Server Database Engine, as it controls data processing, storage, and security. Beneath the Database Engine is the SQL Server Operating System, which is used for memory and I/O management, locking data to avoid unneeded upgrades, and job scheduling.

The solution has four editions with different sets of services and tools. They include:

SQL Server Developer
SQL Server Expression
SQL Server Standard
SQL Server Enterprise

The first two are available for free and are typically utilized by smaller companies, as they work with fewer functions and storage. The second two editions are generally used by bigger organizations and enterprises and offer more features.

The solution has several functions through which users can facilitate different data-related processes. These include:

Aggregate functions: These functions are used to calculate one or more values and return a single value.
Window functions: Window functions calculate an aggregate value based on a group of rows and return multiple rows for each involved group.
Date functions: These functions allow clients to handle data and time data efficiently.
String functions: Through the string functions, SQL Server processes an input string and returns a string or numeric value.
System functions: The system functions of the product return objects, values, and settings.

SQL Server Services

SQL Server has a wide range of add-on services that provide additional benefits beyond database management. These services include:

Machine learning: SQL Server machine learning services allow users to do machine learning and data analytics within the product.
Service broker: This feature is a part of the database engine and offers messaging and message queuing for applications on the platform.
Replication: This feature consists of transaction replication, merge replication, and snapshot replication.
Analysis: SQL Server Analysis Services (SSAS) adds online analytical processing (OLAP) and data mining capabilities to SQL Server databases.
Reporting: This feature supports the development of custom reporting applications.
Notifications: This feature generates data-driven notifications which are sent to subscribers of Notification Services.
Integration: This SQL Server feature provides capabilities for data integration, data import, and data warehousing.
Full-text search: Through this feature, users can utilize specialized indexing and query for unstructured text stored in the solution.
Visual studio: This feature supports data programming with SQL Server.
Azure Data Studio: This is a cross-platform query editor that can be downloaded and used alongside SQL Server.

SQL Server Benefits

The solution has many benefits for users. These include the following:

The platform ensures a consistent experience across other platforms while being fast and agile.
Through the built-in intelligence features, users can understand their data better.
The solution has enterprise-level security, which ensures the smooth and safe performance of users' data.
SQL Server offers the ability to retrieve large amounts of data quickly and efficiently.
The product installation process is fairly easy, and it offers a user-friendly interface.
SQL Server offers improved data storage and retrieval functions through frequent upgrades.
The solution reduces the risk of database server attacks, since it is not an open-source database.

Reviews from Real Users

A president at a consultancy evaluates SQL Server as a veteran solution with critical log shipping feature.
