Hi,
   I have an Oracle table with a single field called 'rundate'. This field contains a date in the format of date. I need to retrieve this using pro*c code and convert it a number(5) value. Any help would be much appreciated.

Thanks,
          Dust

    Hi dustybryn,
    You can do that in Oracle directly. Here's an example of converting an Oracle date into C-style time_t:

    select (effective_date - to_date('19700101','YYYYMMDD')) * 86400 time_t from subscriber

    Whatever the anchor date for your calendar operation is, you can use the same approach. Example: Number of days since 01/01/2000

    select trunc(effective_date - to_date('20000101','YYYYMMDD')) millenium_days from subscriber


    Cheers!
