You have SQL syntax error in the SQL generated by hibernate. The hibernate generates SQL according a dialect used by the configuration settings and it does it right, so there should not be errors if you have used HQL or criteria queries. If you are using MySQL JDBC driver then you are connecting to the MySQL database. HQL uses object mapping to get names for the tables and columns used by the query. If you are using save via hibernate session object then insert SQL statement is generated. The error
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'option, createdBy, createdDate, updatedBy, updatedDate, description) values ('QU' at line 1
shows you which column name is wrong. You can also check Reserved Words from the MySQL Reference Manual.
Usually such names can be used in the SQL if they are backquoted. For example specifying a column name as `option`. But it's MySQL specific, and better rename it to something not reserved.
