Hi, I have created a quiz and the questions get read from a MySql database table. I am now wanting to stop it repeating questions, when I first started this I thougt it would be easy just create a column called Duplicate and everytime a question got pulled I would mark it in the databse. So it would only read questions that had a "0" in the DuplicateCol and after reading the question it would put a "1" in place of the "0" That would work, the problem being multiple people are using it so if a 1 is there they wont all get asked the question. Anyway that idea is a fail now, which is a shame because everything else worked. Im hoping someone can show me another way on stopping duplicates. when I created the quiz I created a registration, and login page which have there own table I then created another table for the questions with multiple columns ie " id, Question, Answer1, Answer2, Answer3, CorrectAnswer, DuplicateCol " I had a number on my form which is a random number that lets say is "6" will then pull the question from column id 6 Query = "select Question,Answer1,Answer2,Answer3,CorrectAnswer,DuplicateCol from Questions where DuplicateCol= '0' AND id='" + RandomN.Text + "'" Anyway im for the time being lost until someone can give me ideas please, The registration, login table looks like this id, Serial, Email, UserName, Location, UserScore, Activated, I was thinking of adding q1, q2, q3, q4, q5, etc etc and then somehow if a question got pulled in my questions table with id "6" then put a "1" in the column but I think it might be to hard to try and cross reference 2 tables. Any Ideas ?
