实现从nklesson_plan中选出Lesson_id(多个),利用Lesson_id在nklesson中选出teacher_id。
我的实现:
select teacher_id from nklesson where nklesson.Lesson_id in (select Specialty_id,Class_con,Lesson_id,Term_id,Week_time
from nklesson_plan
where (Specialty_id=:Specialtyid) and (Grade=:Grade) and (Term_id=:Termid))
错误提示:Invalid use of keyword,Token:,class_con,Lesson_id,
