   > I would rather go with check if preparedstatment is closed or not rather 
than wrapping it in `try`...`catch`. Is there anything blocking here to go that 
way?
   
   Thanks @snuyanzin for the suggestion.
   As the JDBC Statement definition, If the database access error occurs we may 
also meet SQLException.
