Solution 1

The simplest approach would be to get all the questions to your client and then randomly select 10 out of them. You should be able to pick 10 using the primary key for questions in the table (or something similar).

Hi,

this is what I would do:
1. make sure your questions table has a uniqueID field, which holds a unique integer value;
2. fetch all those uniqueID values (or all the ones you're interested in) using one of these:

SELECT uniqueID FROM table 
SELECT uniqueID FROM table WHERE selection

and store them in a collection, say a List of Integers
3. now each time you need a question, randomly pick a uniqueID from your list, and fetch the question using

SELECT * FROM table WHERE uniqueID=theOneYouWant

4. Don't forget to remove the uniqueID once you have processed the question, otherwise the same one might come up again!
