错误写法：
create or replace procedure testproce20130228
is
sqlstr varchar2(8000);
date1 varchar2(10);
begin
select sysdate into date1 from dual;
sqlstr:= 'insert into testtbl values(''test2222'','''||(select to_char(date1,'yyyy-mm-dd') from dual)||''')';
execute immediate sqlstr;
commit;
end;
正确写法：
create or replace procedure testproce20130228
is
sqlstr varchar2(8000);
date1 varchar2(10);
begin
select to_char(sysdate,'yyyy-mm-dd') into date1 from dual;
sqlstr:= 'insert into testtbl values(''test2222'','''||date1||''')';
execute immediate sqlstr;
commit;
end;
