执行提示错误：表不存在

[四川张三丰]

declare

vrowcount number;
vtotal number :=0;
v_createSQL varchar2(2000);
cn number:=0;
begin

v_createSQL :='create table TBSJ_LOG
(
id NUMBER(10),
pr_name VARCHAR2(50),
table_name VARCHAR2(50),
pcdm VARCHAR2(14),
message VARCHAR2(200),
step NUMBER(3),
update_time DATE default sysdate
)';

select count(1) into cn from all_tables where TABLE_NAME = 'TBSJ_LOG' and OWNER='YLH';

if cn = 0 then

execute immediate v_createSQL;

end if;

for i in 1..15001/5000 + 1 loop

delete from ypml_x_2018_01_cs where rownum<=5000;

vrowcount := sql%rowcount;
vtotal := vtotal + 1;

insert into TBSJ_LOG
(message, update_time)
values
(to_char(vrowcount) || '数据已删除', sysdate);
commit;
end loop;

end;

我在执行这语句的时候，提示TBSJ_LOG 不存在，但是前面有创建TBSJ_LOG的语句。请高手帮看看？

insert into TBSJ_LOG, 这个句也写成动态的。
