I changed the database.now it's working.
But the problem is iam trying to insert into table choices.
if i type,
"insert into choices(bookname, isbnnumber)values('java','1234')"
it's inserting the string java and 1234.
now,
what i want to do is,
i want to insert data where data is a variable whose value is java.
what is wrong with this?
"insert into choices(bookname, isbnnumber)values(data,'1234')"
thanks in advance
