    delete from table

    Hi..
    i'm running this query monthly, delete from table_name where date_of < given_date;

    it is a big table, and the database is managed by the application,how can i compact the database (oracle 8.1.7 on unix) regarding free space on the database file?

    i do not want to do truncate, is there a diffrent way?

    10X in advance

    why do you want to, the space will be re-used when new data is added?

    hi again....
    the free space is for ~ 7 % from 1GB, i'm doing this preventing the datafile becoming full, or i have to alter its size or add an extra datafile.

    yeah - but why? the free space in the table will get re-used by the new inserts and the datafile wont need to grow.

    Anyhow sounds like you need partitions by range on a date so you can drop a partition whenever you want to
