    Hi all, 

    I'm attempting to create a report using the standalone Report Designer. Whenever I try to run the report, I get the below error;

    MySql.Data.MySqlClient.MySqlException

    Can anyone please give me some insight as to why this is happening? If you need more information, please let me know.

     

    Thanks!

    Hi Samuel,

    We will need more details about the scenario of the report and the data. Is the report coming from the report server? If so, what kind of MySQL data provider do you use? 

    For further information, you can refer to How to: Connect to MySQL Database.
