SUGGESTION: TRANSACT-SQL LIKE "PIVOT" AND "UNPIVOT"

Hi!

I would like to suggest that MariaDB implements PIVOT and UNPIVOT SQL Statements, just as TRANSACT-SQL does:

Using PIVOT and UNPIVOT (TRANSACT-SQL)

CONNECT Pivot Table Type already exists, but I personally think that a feature such as pivoting and pivoting should be SQL Syntax native.

Thank you
