是否可以在MySQL中顯示值「show variables」？

Question

它是一件容易的事找到MySQL的變量值：

 
mysql> show variables where Variable_name = 'version'; 
+---------------+--------------------+ 
| Variable_name | Value    | 
+---------------+--------------------+ 
| version  | 5.0.19-Max   | 
+---------------+--------------------+ 
1 row in set (0.00 sec) 

但是它有什麼語法，允許使用的變量值只選擇列，就像這樣：

 
mysql> command_i_want_to_know 
+--------------------+ 
| Value    | 
+--------------------+ 
| 5.0.19-Max   | 
+--------------------+ 
1 row in set (0.00 sec) 

Answer 1

還有一變體 -

SELECT @@version; 

Answer 2

select variable_value 
from information_schema.global_variables 
where variable_name = 'version';
