Filter the output of show global status

[Marcel Pfiel]

Hello,
i am trying to monitor a mysql database with Icinga. So Icinga runs a script with a sql statement and expect a single number as return code. When Icinga run following sql statement:

show global status like "Com_delete";

MariaDB returns 2 columns. Variable_name & Value. Like this:

+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| Com_delete | 40927 |
+---------------+-------+

How can i filter this statement that i just get this:

+-------+
| Value |
+-------+
| 40927 |
+-------+

But i have to realize it only with sql to use it with Icinga. Can somebody please help. I dont have any idea how to google this :D
