Nested Exception could not execute statement - HTTP Status 500 - Hibernate : I've been working on project in Spring, I'm trying to add functionality which will add int ( mark in this case ) to my MySQL database but after clicking button I've a following error: 

    HTTP Status 500 - Request processing failed; nested exception is org.springframework.orm.hibernate5.HibernateJdbcException: JDBC exception on Hibernate data access: SQLException for SQL [n/a]; SQL state [HY000]; error code [1364]; could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement


This is the log from the console: 

    SEVERE: Servlet.service() for servlet [dispatcher] in context with path [/eschool] threw exception [Request processing failed; nested exception is org.springframework.orm.hibernate5.HibernateJdbcException: JDBC exception on Hibernate data access: SQLException for SQL [n/a]; SQL state [HY000]; error code [1364]; could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement] with root cause

These are my classes and the view:

Teacher.class
https://paste.ofcode.org/v6EHpJL5v5QSPmgis4ZPcZ

MarkDAO
https://paste.ofcode.org/NtqNgS6FqrbR6DRiWdNRNJ

MarkDAOImpl
https://paste.ofcode.org/33QPdkTZXhfaUi2th5uydbP

TeacherController - I'm adding mark in this class
https://paste.ofcode.org/QUC7BDiwAPgAkMW6Uznyb2

and the view - it suppose to change from disable to enable but it's not working too, don't know why exactly... I've got three students there but it shows 0 :/

If you'll need more logs or another class, which I forgot to add, let me know in a comment.

Please help, it's urgent :/
