本过程适用于Oracle数据量统计。

create or replace procedure SP_GET_TAB_COUNT
 as
   v_tableName HDSD_TJ.Tablename%type;
   v_tableCount  HDSD_TJ.Tablecount%type;
   v_tmp varchar2(500);
   v_tmp2 varchar2(500);
   v_tmp3 varchar2(500);
   cursor cur_tab is  select tableName from HDSD_TJ;
 begin
   open  cur_tab;
   loop
     fetch cur_tab into  v_tableName;
     exit when  cur_tab%notfound;
        v_tmp:=‘analyze table  ‘||v_tableName||‘  estimate statistics‘;
        execute immediate v_tmp;
        v_tmp2:= ‘select num_rows  from tabs where table_name =‘‘‘||v_tableName||‘‘‘‘;
        execute immediate v_tmp2 into  v_tableCount;
        v_tmp3:=‘update HDSD_TJ set Tablecount=‘||v_tableCount||‘ where tableName =‘‘‘||v_tableName||‘‘‘‘;
        execute immediate v_tmp3;
   end loop;
   close  cur_tab;
 end;

-- Create table
create table HDSD_TJ
(
  tablename  VARCHAR2(100),
  tablecount NUMBER(12)
)
