插入字段时字符串里含‘--’被注释怎么办？

SQL> create table tempt(
  2  id int,
  3  name varchar(20)
  4  );
SQL> insert into tempt values(1,'hello');
SQL> insert into tempt values(1,'--');
SQL> COMMIT;

create table tempt(
id int,
name varchar(20)
);

SQL> select * from tempt;

        ID NAME
---------- --------------------
         1 hello
         1 --
