Hi, I have a database that has millions of datas, and I need to show it dynamically. Right now I have created the dynamic query, and it works fine locally. But when my report is uploaded to the server, it becomes so very very slow. Could anyone help me solve my problem? (In my report, there is only one chart, 6 parameters, the chart can show 6 different series based on user's selection)
