IO have a problem comparing two time ranges i.e. 01.01.2008-31.01.2008 with 01.01.2009-31.01.2009.I managed to define the parameters for one time range, but when I try to do the same for a second time frame it does not give me the results.Any ideas on how to find a solution are appreciated? |

how do you want to compare time frames? compare startdates and enddates? |

correct, I have lets say production per day data and want to compare my production for Jan 08 with Jan 09.At the moment I can only include in my report one range as parameter start/ end date. Maybe I am missing something here. |

that's easy . just pass two date alone (start and end). and in your query use a temporary table. first get data for period start-end and populate it. then populate it with data for period start-1year to end-1 year. then return the data from temporary table grouped on year value |
