    auto analyze partition !!

    the following SP is not working tho it compiles fine.
    Looks like the "for x in select " is not working....any suggestion ??

    CREATE OR REPLACE PROCEDURE analyze_partition(
    part_name IN VARCHAR2)
    IS
    TYPE x_type IS REF CURSOR;
    x x_type;
    x_part_name varchar2(200) := upper(part_name);

    BEGIN
    dbms_output.put_line('X_PART_NAME: '|| x_part_name);
    for x in (select table_name,partition_name from dba_tab_partitions
    where table_owner = 'MDM3'
    and partition_name like 'x_part_name%'
    and last_analyzed is null)
    loop
    begin
    exec sys.dbms_stats.gather_table_stats(ownname => 'MDM3', -
    tabname => x.table_name, -
    partname => x.partition_name, -
    estimate_percent => 30, -
    block_sample => false,-
    method_opt => 'FOR ALL COLUMNS SIZE 1', -
    degree => 8, -
    granularity => 'default', -
    cascade => true , -
    stattab => null, -
    statid => null, -
    statown => null);
    exception
    when others then
    dbms_output.put_line('### ERROR: ' || sqlerrm);
    end;
    end loop;
    end;

    Remove exec before sys.dbms_stats.
    It is not needed if it is called between begin and end.

    You do not need REF Cursor because you are not returning any thing.

    Also, "-" is not needed. For example: tabname => x.table_name, -

    Code:
    and partition_name like x_part_name||'%'

    and partition_name like 'x_part_name%'
    should be
    and partition_name like x_part_name||'%'

    I'm taking a more leisurely approach to life. And if you can only beat me to it by a matter of seconds, you'd better look to your laurels, young whipper-snapper.

    Wouldn't it make sense to simply use dbms_stats?
    I think GATHER_SCHEMA_STATS with the parameter OPTIONS set to GATHER AUTO, GATHER STALE or GATHER EMPTY would be a nicer solution.
