Hello Agata,  
I just upgraded clover to 3.1 . I ran the same graph ( with incremental key in the where clause) in this new version . I am getting this error message:  
java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@15546f86 is still active. No statements may be issued when any streaming result sets are open and in use on a given connection. Ensure that you have called .close() on any active streaming result sets before attempting more queries.

I don’t understand the error message very well. What could be the reason ? Is there error code, description file I can look into ?  
Thanks in advance for your help.  
Regards,  
Kasturi

Hello Kasturi,  
the issue has been logged in our bug tracking system: [https://bug.javlin.eu/browse/CL-1861](https://bug.javlin.eu/browse/CL-1861). Use guest/guest credentials for browsing it. As a workaround please set _Generic_ jdbc specific in your MySQL connection.
