从Pentaho报表设计器查询远程Oracle数据库时出错

Question

I'm trying to get some data from a remote Oracle Database, so I configured a new connection to the database and whn I press Test, it says that the connection was established succesfully, but when i tried a simple select query, Report Designer gives me an error:

org.pentaho.reporting.engine.classic.core.ReportDataFactoryException: Failed at query: select * from fact_table;

So how can I get this done?

Answer 1

select * from fact_table; seems to be a valid query. Try to remove the semicolon at the end.
