（Oracle）数据量统计存储过程

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

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