    Unhappy

    Hi there,

    I am running the following script to give me information about the size and growth of objects..

    All data is pulled from the data_dictionary except check_date which is sysdate..

    insert into APRODBSEC
    ( TS , Seg_Owner , Seg_Name , Seg_Type , bytes , Blocks , Extents
    next_extent , max_extents , Check_Date)
    select
    d.Tablespace_Name, d.Owner, d.Segment_Name, d.Segment_Type,
    d.bytes, d.blocks, d.Extents, d.next_extent, d.max_extents, TRUNC(SysDate)
    from DBA_SEGMENTS@APRODBSEC.world D
    where Owner = UPPER('schema_owner')

    DBA_SEGMENTS@APRODBSEC.WORLD is a database link I have set up to another database on another server (this all works fine)

    I am looking to pull information from this table which will give me information of the growth of the objects.

    I have a script which works using a decode function
    select
    TS,
    Seg_Owner,
    Seg_Name,
    Seg_Type,
    MAX_EXTENTS,
    MAX(DECODE(Check_Date, TRUNC(SysDate-7),
    extents,0)) LastWeek,
    MAX(DECODE(Check_Date, TRUNC(SysDate),
    extents,0)) Today,
    MAX(DECODE(Check_Date, TRUNC(SysDate-7),
    extents,0)) Change
    from APRODBSEC
    group by
    TS,
    Seg_Owner,
    Seg_Name,
    Seg_Type,
    MAX_EXTENTS;

    The problem with this is that if the script is ran on a different day than the data is inserted I get no output

    This means for instance if the data was inserted into the table on 27-FEB-01 and the script was run on 01-MAR-01 the DECODE part show up with a 0.

    I am looking for help in adapting this scrip so that it works no matter what day it's ran..

    I was thinking of something using
    CHECK_DATE-(MAX(CHECK_DATE)-TRUNC(SYSDATE))
    but I can't get it to work


    Many thanks to anyone who can help
