BEGIN

   INSERT INTO test_table VALUES('test', REALLYBIGTEXTSTRING, '0');
end ;

commit;

--生成定義

select 'RT_1_'||rownum||' CLOB :=#'||dbms_lob.substr(a.award,4000,1) || '#;RT_2_'||rownum|| 'CLOB :=#'||dbms_lob.substr(a.content_area,4000,1) || '#;'    from achivement_bak a  order by a.remarks desc

update achivement_bak SET award = replace(award,'chr(38)','&'),content_area = replace(content_area,'chr(38)','&');
