不好意思本人新手

看不出那错了

这样写：
insert into stutab(class,grade,number,teacher,others) values(:ls_class,:ls_grade,:ls_number,:ls_teacher,:ls_others) Using SqlCa;
加冒号，绑定变量

变量前面加冒号：
insert into stutab(class,grade,number,teacher,others) values(:ls_class,:ls_grade,:ls_number,:ls_teacher,:ls_others) Using SqlCa;
