hi all,

i have a small doubt in one of my application, i am working on an online examination system.
i want to know how to update record in database.

the database has four columns (question_id,subcode,correctanswer,useranswer)
and the exact problem in updating is:

suppose i have the question id alreay in the database and corresponding user option with it.
but i the option for the qid is changed then it should also reflect in the database.

thanks in advance.

First you identify which fields uniquely identify the option. Then you write a SQL statement to update the value. Then you add JDBC.
