Hello everyone,

I am able to successfully create and insert entries in a table via Hibernate, however for some reason I am unable to update records within my database created by Hibernate. I created an individual method for update and delete as seen below (NOTE: I have also included the POJO class I created):



As aforementioned, the table is successfully created in a MySQL database. However, I am unable to update an objects Marks (grade) via my HQL query:



The purpose of the update method is to effectively take one of the records in the table via the id column and updates the element in the marks column.
 
It is sorta covered in the JavaRanch Style Guide.
