Hi, I am beginner of iReport, but I think that is a bug. I've done a mysql connection with JDBC, the connection work. I done a simple report with a simple query "select * from table_name", and I placed few fields into details section. When I see the preview report I see only one record detail but table has many records. I see also that into window Report Query, if I click on "Refresh Preview Data" Button with "All" option selected, in below list only one record is showed. Instead if I select "First 100 records" and then click on "Refresh Preview Data" Button, an error is showed: "Error net.sf.jasperreports.engine.JRException:"Erro executing SQL statment for:data" Any idea
