We're Moving to a New Support Platform – Starting June 1st!

We’re excited to let you know that starting June 1st, we’ll be transitioning to a new support system that will be available directly on our product websites – Amelia, wpDataTables, and Report Builder. In fact, the new support platform is already live for Amelia and wpDataTables, and we encourage you to reach out to us there.

You'll always be able to reach us through a widget in the bottom right corner of each website, where you can ask questions, report issues, or simply get assistance.

While we still do not offer live support, a new advanced, AI-powered assistant, trained on our documentation, use cases, and real conversations with our team, is there to help with basic to intermediate questions in no time.

We're doing our best to make this transition smooth and hassle-free. After June 1st, this current support website will redirect you to the new "Contact Us" pages on our product sites.

Thanks for your continued support and trust – we’re excited to bring you an even better support experience!

    Hi

    If a chart is build by SQL query, which is not simple and contains some calculations, what are methods to speed up the chart building in the frontend?

    Hi Evgeniy

    Thank you for reaching out to us.

    If you are building a complicated SQL query the best solution would be to prepare a MySQL view (a stored query), which will return the data that you need, call it e.g. “view1” and then build a wpDataTabled 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.
