Oracle表分析

create or replace procedure P_ANALYZE_TABLE is
  cursor loop_tmp is SELECT 'ANALYZE TABLE '||TABLE_NAME||' COMPUTE STATISTICS' dynamicSql FROM USER_TABLES;
begin
  for tmp in loop_tmp loop
    execute immediate tmp.dynamicsql;
  end loop;
end P_ANALYZE_TABLE;

oracle的表随着数据量的增大，需要不断的优化，分析表是个很关键的步骤
