    I followed this model in one of my application , and it works smoothly and fast.
    I have MYSQL as Server.

    The only thing I noticed was records missing at Client site, after a few hours of debugging I found the reason .

    I need to set TFDQuery FetchOptions Mode to fmAll before


    if not I only received 30 rows… ??
