MySQL Version Retrieval Techniques

Question:

How can we retrieve the current version of a MySQL database management system (DBMS)?

Answer:

MySQL provides multiple ways to obtain the current version information:

• VERSION() Function: Executes a simple function that returns the MySQL version string, such as "5.7.22-standard".

SELECT VERSION();
--> '5.7.22-standard'

• SHOW VARIABLES LIKE "%version%": Displays a more detailed table listing various version-related variables, including the protocol_version, version, version_comment, version_compile_machine, and version_compile_os.

SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------------------+
| Variable_name           | Value                                    |

| protocol_version        | 10                                       |
| version                 | 5.0.27-standard                          |
| version_comment         | MySQL Community Edition - Standard (GPL) |
