MySQL vs. SQL
SQL extends for Structured Query Language. SQL is a standard language which enables the user to design and manage databases. On the other hand, MySQL is a relational database management system that allows a user to store and retrieve data from the database. MySQL uses SQL to perform specific operations on the database. Both MySQL and SQL offers two trendy and differentiable servers which are MySQL server and SQL server for database management.
Let's understand the difference between MySQL and SQL server.
SQL is developed by Microsoft Corporation and named as Microsoft SQL Server (MS SQL).
MySQL is developed by Oracle Corporation. Its name is a combo pack of "My (under co-founder daughter's name) and Structured Query Language (SQL)".
MySQL is an open-source software which is available free to all.
SQL is not an open-source software and hence not available free of cost.
3) Platforms support
SQL was originally developed for Windows operating system. Currently, it is supported by Linux and macOS (via Docker), lacking certain features which are supported in the Windows platform.
MySQL works well with Windows, macOS, Linux, Solaris platforms.
4) Programming Languages Support
MS SQL itself is a programming language, but SQL server supports basic programming languages such as C++, Go, R, PHP, Python, Ruby, Visual Basic, etc. In addition to the basic programming languages, MySQL also supports Perl, Haskel, Tcl, etc.
5) Storage Engine
MySQL does not require a large amount of storage space for performing different operations. It supports a multiple number of storage engines. MySQL also supports plug-in storage engines.
On the other hand, MS SQL supports only a single storage engine. Therefore, programmers need to be updated with more improved engines.
6) Security Offered
MySQL is less securable server because it allows database files manipulation by other processors or its own binaries at its execution time only.
But, MS SQL provides a highly securable job. It does not allow database file access or manipulation through other processors or through its own binaries at its execution time.
In MySQL, for data backup, the developer needs to extract it as SQL statements. While backing up the data, the server blocks the database, which reduces the chance of data corruption when switching from one version of MySQL to another.
In MS SQL, the server does not block the database at the time of backup. It means while data backup, the developer can perform other operations on the database.
8) Time Consumption in Data restoration
MySQL consumes a high amount of time for data restoration because it executes multiple SQL statements altogether. While MS SQL makes less efforts and time to restore a huge amount of data.
9) Canceling Query Execution
MySQL does not provide the facility to stop or cancel a query at its execution time. To do so, the user needs to cancel the whole process. Unlike MySQL, the MS SQL server provides the feature to truncate a query at its execution time without disturbing or canceling the entire process.
10) Software Stack Component
The enterprise can select various editions of MS SQL according to the user requirements for the project. On the other hand, MySQL is used by many web application developers as a component of the LAMP stack.
There are two editions available in MySQL. The user can either use MySQL Community Server or MySQL Enterprise Server.
MS SQL is available in various specialized editions. The user can select from web, enterprise, standard, or Express editions of SQL.
MySQL is available only in the English language.
SQL is available in many different languages.
The SQL syntax is easy to use and implement. On the other hand, MySQL syntax is a little bit typical to use and implement.
To implement the length function, following queries will be used as per:
MS SQL: SELECT LEN(req_string) FROM <Table_name>
MySQL: SELECT CHARACTER_LENGTH(req_string) FROM <Table_name>
