The following content mainly brings you the definition and difference of sql server and mysql. The knowledge mentioned here, which is slightly different from books, is summed up by professional and technical personnel in the process of contact with users, and has a certain value of experience sharing. I hope to bring help to the majority of readers.

Sql server and mysql are both widely used relational database management systems (RDBMS), so what's the difference between them? The following article will introduce the difference 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 relational 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 mainly programmed in C + +, but there are also some parts in the C language.

3. Platform

SQL Server supports only Linux and Windows platforms, mainly for .net applications or Windows projects. In contrast, MySQL supports many platforms and is mainly used for PHP projects or applications.

4. Grammar

The MySQL syntax is a bit complicated; the SQL Server syntax is easier to use.

5. Execute the query

In MySQL, once a query is executed, it is not possible to cancel the query halfway. In SQL Server, you can cancel the query halfway through execution.

6. Storage engine

In MySQL, there are several storage engines that give developers more flexibility to use the engine for tables 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, the developer must back up the data by extracting all the data into SQL statements. Because multiple SQL statements are executed, data recovery is very time-consuming. On the other hand, SQL Server does not block the database when backing up data, which allows 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 binaries at run time. It even allows other processes to access and manipulate database files at run time. However, SQL Server does not allow any process to access or manipulate its database files or binaries. It requires users to run instances to perform specific functions or manipulate files. As a result, hackers cannot directly access or manipulate data. Design rules to 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 Perl,Scheme

Programming languages such as Haskel and Eiffel. MySQL is more popular because it supports many programming languages.

10. Filtering

MySQL allows users to filter out tables, rows, and users in a variety of 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. On the other hand, SQL Server uses row-based filtering and row-based filtering options to filter data on the database as a database. And the filtered data is stored in a separate distribution database.

These are the details of what is the difference between sql server and mysql. Please pay more attention to other related articles!
