No Data To Display Error

Recommended Posts



I wonder if you could help me, I am working on using the example FactoryDB MySQL database to pull into a pie chart with a drill down to a Multi line chart.


The pie chart works fine and shows exactly what you would expect i.e. Factory 1, Factory 2 and Factory 3.


I then click on a factory and get the "No data to display error".


I am using JSP to create SQL to pull from the example database "Factorydb". The query I have is as follows...


<c:set var="strQuery" value="select * from factory_output inner join factory_master on factory_master.factoryid = factory_output.factoryid where factory_master.FactoryName='${param.factoryName}' order by DatePro Asc" />


If I replace the '${param.factoryName}' with 'Factory 3' then the query generates the chart as I would expect.


I have also outputted the XML generated using the above query (with the '${param.factoryName}' in place) and there is nothing wrong with the XML generated - I have attached the file.


It would appear that the '${param.factoryName}' makes the difference as to the chart working and it not!


Any ideas?


Thanks in advance
