TOM 大师表分析存储过程

1.使用sys 建存储过程

CREATE OR REPLACE PROCEDURE "SYS"."SHOW_SPACE" 

( p_segname in varchar2,

  p_owner   in varchar2 default user,

  p_type    in varchar2 default 'TABLE',

  p_partition in varchar2 default NULL )

as

    l_total_blocks              number;

    l_total_bytes               number;

    l_unused_blocks             number;

    l_unused_bytes              number;

    l_LastUsedExtFileId         number;

    l_LastUsedExtBlockId        number;

    l_last_used_block           number;

    procedure p( p_label in varchar2, p_num in number )

    is

    begin

        dbms_output.put_line( rpad(p_label,40,'.') ||

                              p_num );

    end;

begin



    dbms_space.unused_space

    ( segment_owner     => p_owner,

      segment_name      => p_segname,

      segment_type      => p_type,

      partition_name    => p_partition,

      total_blocks      => l_total_blocks,

      total_bytes       => l_total_bytes,

      unused_blocks     => l_unused_blocks,

      unused_bytes      => l_unused_bytes,

      last_used_extent_file_id => l_LastUsedExtFileId,

      last_used_extent_block_id => l_LastUsedExtBlockId,

      last_used_block => l_last_used_block );



    p( 'Total Blocks', l_total_blocks );

    p( 'Total Bytes', l_total_bytes );

    p( 'Unused Blocks', l_unused_blocks );

    p( 'Unused Bytes', l_unused_bytes );

    p( 'Last Used Ext FileId', l_LastUsedExtFileId );

    p( 'Last Used Ext BlockId', l_LastUsedExtBlockId );

    p( 'Last Used Block', l_last_used_block );

end;

2. 为其他用户建立同义词

SQL>  create public synonym show_space for sys.show_space;

Synonym created.

SQL> set  serveroutput  on

SQL> exec show_space('EMP')
Total Blocks............................8
Total Bytes.............................65536
Unused Blocks...........................4
Unused Bytes............................32768
Last Used Ext FileId....................9
Last Used Ext BlockId...................112
Last Used Block.........................4
