如何检索MySQL数据库的当前版本?
什么命令返回当前版本的MySQL数据库?
试试这个function –
SELECT VERSION();
版()
或者更多细节使用:
SHOW VARIABLES LIKE "%version%";
MySql – 确定版本
尝试
mysql --version
例如。 或者dpkg -l 'mysql-server*'
。
对于UBUNTU,您可以尝试以下命令来检查mysql版本:
mysql --version
mysqladmin version
或者mysqladmin -V
我find了一个简单的方法来获得这个。
例如:Unix命令(这样你不需要2个命令)
$ mysql -u root -p -e 'SHOW VARIABLES LIKE "%version%";'
示例输出:
+-------------------------+-------------------------+ | Variable_name | Value | +-------------------------+-------------------------+ | innodb_version | 5.5.49 | | protocol_version | 10 | | slave_type_conversions | | | version | 5.5.49-0ubuntu0.14.04.1 | | version_comment | (Ubuntu) | | version_compile_machine | x86_64 | | version_compile_os | debian-linux-gnu | +-------------------------+-------------------------+
在以上情况下,mysql版本是5.5.49 。
请find这个有用的参考 。
SHOW VARIABLES LIKE "%version%";
确定你当前的MySQL版本
shell> mysql --version shell> mysql -V
在Ubuntu上使用mysql -V可以正常工作
从控制台你可以尝试:
mysqladmin version -u USER -p PASSWD
只需使用login到Mysql
mysql -u root -p
然后input这个命令
select @@version;
这会给出结果,
+-------------------------+ | @@version | +-------------------------+ | 5.7.16-0ubuntu0.16.04.1 | +-------------------------+ 1 row in set (0.00 sec)
login到你的mysql,复制并粘贴这个:
SHOW VARIABLES LIKE "%version%";
示例输出:
mysql> SHOW VARIABLES LIKE "%version%"; +-------------------------+---------------------+ | Variable_name | Value | +-------------------------+---------------------+ | protocol_version | 10 | | version | 5.1.73 | | version_comment | Source distribution | | version_compile_machine | i386 | | version_compile_os | redhat-linux-gnu | +-------------------------+---------------------+ 5 rows in set (0.00 sec)
在Ubuntu和其他Linux varian, SELECT @@version
上试过这个,工作得很好。
当您第一次login时,您也可以查看MySQL shell的顶部。它实际上在那里显示版本。

用CLI在一行中:
mysql --user=root --password=pass --host=localhost db_name --execute='select version()';
要么
mysql -uroot -ppass -hlocalhost db_name -e 'select version()';
返回这样的东西:
+-----------+ | version() | +-----------+ | 5.6.34 | +-----------+
