Question

I need to fetch a scalar value of the MySQL VARIABLE “version”. Currently running this:

SHOW VARIABLES WHERE Variable_name="version"

Is giving me a table like:

Variable_name    Value
-------------    -----------
version          5.5.28-log

How do I just get the Value cell?

Answer 1

Okay, I found out how:

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