SQL server and mysql are both widely used relational database management systems (RDBMS), so what are the differences between them? The following article will introduce to you the differences between sql server and mysql. I hope it will be helpful to you.
The difference between MySQL and SQL Server:
1. Open source
MySQL is an open source relationship Database management system (RDBMS); SQL Server is not open source, it is commercial.
2. Program
MySQL is mainly programmed in C and C programming languages. SQL Server is primarily programmed in C, but there are some parts in the C language.
3. Platform
SQL Server only supports Linux and Windows platforms and is mainly used for .Net applications or Windows projects. In comparison, MySQL supports many platforms and it is mainly used for PHP projects or applications.
4. Syntax
MySQL syntax is a bit complicated; SQL Server syntax is simpler and easier to use.
5. Execute query
In MySQL, once the query is executed, it cannot be canceled midway. In SQL Server, it is possible to cancel a query midway after execution.
6. Storage engine
In MySQL, there are multiple storage engines that allow developers to use engines for tables more flexibly based on performance. InnoDB is a popular storage engine. SQL Server can only use one or only one storage engine.
7. Backup
When using MySQL, developers must back up the data by extracting all data as SQL statements. Data recovery is very time-consuming due to the execution of multiple SQL statements. And SQL Server does not block the database when backing up data, which enables users to back up and restore large amounts of data without spending extra time and effort.
8. Security
Both enterprise database systems are designed as binary collections, and MySQL enables developers to manipulate database files through binary files at runtime. It even allows database files to be accessed and manipulated by other processes while running. But SQL Server does not allow any process to access or operate its database files or binary files. It requires users to perform specific functions or manipulate files by running an instance. Therefore, hackers cannot directly access or manipulate the data. Design rules make SQL Server more secure than MySQL.
9. Supported programming languages
Both MySQL and SQL Server support multiple programming languages. They all support PHP, C, Python, Visual Basic, etc. But MySQL also supports programming languages such as Perl, Scheme,
Haskel and Eiffel. MySQL is more popular due to its support for many programming languages.
10. Filtering
MySQL allows users to filter out tables, rows and users in many ways, but it requires users to filter out tables, rows or users by individual databases. When filtering data, developers must filter database tables individually by running multiple queries. SQL Server uses row-based filtering, and row-based filtering options filter data on the database in a database manner. And store the filtered data in a separate distribution database.
