I think that the KB contains docs for a feature which is not really implemented:
https://mariadb.com/kb/en/explain-analyze/
The page says:
"SHOW EXPLAIN was introduced in MariaDB 10.0.5."
However, when running the example query on 10.0.5, I get a syntax error:
MariaDB [(none)]> SELECT VERSION();
+--------------------+
| VERSION() |
+--------------------+
| 10.0.5-MariaDB-log |
+--------------------+
1 row in set (0.01 sec)
MariaDB [(none)]> explain analyze select * from tbl where key1 between 5000 and 5050 and col1='val-1'\G
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'analyze select * from tbl where key1 between 5000 and 5050 and col1='val-1'' at line 1
