Which version is my MySQL Server?

Question

What's the query syntax to determine the exact version number of the MySQL server software?

Answer 1

Besides the already mentioned solutions you can simply see the version if you type mysql in your shell. You will get something like this:

[nikola@localhost]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 386102
Server version: 5.1.61 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Where you can see that the version is printed in the line Server version: 5.1.61 Source distribution.

mysql --version
