MSSQL is often confused for a “Windows-only” RDBMS. Compatibility and Operating Systems Architecture With that in mind, here are some of the key differences between MSSQL and MySQL RDBMS. Average users – and even some developers will likely not notice these differences, however, database administrators – or DBAs – most certainly will. Read: Best Relational Database Software (RDBMS) What is the Difference Between MSSQL and MySQL?Īs mentioned, MSSQL and MySQL are pretty similar in terms of functionality, user interface (UI), and relational database features. First and foremost, you should know SQL – once you have a good grasp on that, then you can look into the ins and outs of each RDBMS. When it comes to simply querying databases, though, do not worry too much about what RDBMS you are using. However, if you would like to use a RDBMS that is open source, you may not want to use Microsoft SQL Server and use something like MySQL instead. For instance, if you or your company mainly uses Microsoft products, you may opt for SQL Server. Selecting the top ten rows in MySQL would look like this: SELECT *Īgain, a minor difference (and there are others) but if unaware, they will be sure to cause a headache.īesides what’s listed above, there may be other small reasons why you would choose one RDBMS over the other. ![]() Not all RDBMS’ support the “ SELECT TOP” command featured in Microsoft SQL Server, including MySQL. Fortunately, most of the core functions in each RDBMS are about the same, however there are some minor differences.įor example, if you want to select the top ten rows of your database in Microsoft SQL Server, it would look like this: SELECT TOP 10 In fact, Microsoft SQL Server has its own unique set of extension commands called Transact-SQL, or T-SQL. The next biggest difference is writing commands in SQL. That being said, you will want to stick to the style guide of your organization, database admin, and development team. That means functions like Select, From, and Where can be all lowercase if you want them to be – the choice is yours. Case sensitivity only applies to data points within the table, not functions of SQL. Keep in mind, some people may choose to capitalize SQL commands as a personal means of organization (the same usually goes for spacing). The first example is a WHERE clause in MSSQL, while the second is also a WHERE clause, only presented in MySQL: Microsoft SQL Server: WHERE Name = ‘Michael’ Observe the difference between the two syntaxes below. There are many reasons why a query might come up unvalid, and, more often than not, it is because of something silly like forgetting to adhere to case sensitivity. Microsoft SQL Server – or MSSQL – is case sensitive, while MySQL is not. The biggest overall difference in syntax between each RDBMS is whether it is case sensitive or not. Generally speaking, once you know one RDBMS, you know them all – as long as you are aware of the differences between them, the differences in syntax, and the management features of each. Each RDBMS has its own dialect, which are typically very similar. The biggest difference between most RDBMS is on the administrative side, but for this article, we are mainly focusing on the syntax. In this article, we will focus on two of the most popular ones – Microsoft SQL Server and MySQL and look at some brief differences between the two.Īs stated earlier, when it comes to the basic functions of a RDBMS, there really is not much of a difference. While each can perform the basic functions required of a relational database, they vary to some degree. Through a RDBMS, you can query databases by using structured query language (SQL). Relational databases consist of organized collections of data points that have defined relationships between them. A relational database management system (RDBMS) is a software used to store, manage, query, and extract data that is in a relational database.
