Description

The TO_CHAR function converts an expr of type date, datetime, time or timestamp to a string. The optional fmt argument supports YYYY/YYY/YY/RRRR/RR/MM/MON/MONTH/MI/DD/DY/HH/HH12/HH24/SS and special characters. The default value is "YYYY-MM-DD HH24:MI:SS".

In Oracle, TO_CHAR can also be used to convert numbers to strings, but this is not supported in MariaDB and will give an error.
