  1. 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 ?
  2. Hi, I have a MySql query which currently looks like this Query = "select Question,Answer1,Answer2,Answer3,CorrectAnswer,id,Duplicate from Questions where id='" + RandomN.Text + "'" As you can see I have a table called 'Questions' which has several columns, Im using VB.NET I also have a textBox on a windows form called 'RandomN' What this does is it takes whatever number is in my textBox called RandomN.Text and looks for that number in the id column and returns all data on that row. What I am trying to acheive now is this, I have a column called Duplicate it will either contain the word 'True' or 'False' I would like it to only return data from the given number in the textBox if the Duplicate column in that row contains the word 'False' If someone can shed some light I would be greatful. Thanks
