The Dynamic columns feature was introduced in MariaDB 5.3.
 
Syntax
------ 
COLUMN_LIST(dyncol_blob);
 
Description
----------- 
Since MariaDB 10.0.1, this function returns a
comma-separated list of column names. The names are quoted
with backticks.
 
Before MariaDB 10.0.1, it returned a comma-separated list of
column numbers, not names.
 
See dynamic columns for more information.
