Hello Christoph

You would only be able to pivot the table in the database, and then prepare a MySQL view (a stored query), which will return that pivoted table, call it e.g. “view1” and then build a wpDataTable based on a simple query like “SELECT * FROM view1″.

Please note some this when working with the server-side processing feature:

• Please do not use “LIMIT” in the SELECT statement. wpDataTables adds it automatically and it will be overridden.
• Please do not use “ORDER BY” in the SELECT statement. wpDataTables has its own sorting engine so it makes no sense to use MySQL’s sorting, since it will be overridden. Also, server-side processing feature adds this part of statement automatically when users trigger the sorting on the front-end, and having it in initial statement may cause the table to crash.
