First you should select a record form "TICKETINFO_REMARK" table with TICKETINFOID. If it already found you should delete this record from "TICKETINFO_REMARK" table and then insert new record with this TICKETINFOID.It is only logic for your requirement. If you want to get sample code, please tell me which technology did you use for your CRUD operation for example JPA, HIBERNATE, IBATIS OR JDBC etc.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
