title: What's a good way to store an array of integers (java) to MySQL database
body: <p>I've been looking at various solutions for my problem, but I can't find a definitive answer for my specific case, so wondered whether someone could advise me or point me in the right direction.</p>
  
  <p>In my Android Studio app, I have a 2-dimensional array of ints (representing a grid of colours). Currently the maximum size of the grid is 250x250, but I may increase that in the future. I know the size of the grid in advance.</p>
  
  <p>I want to store this array in a MySQL database.  I was imagining something like a comma-separated string ("1,2,3; 7,8,9", for instance), but then read about serialization and wondered whether that would be better. The more I read about it, though, the more I thought it might be overkill for what I'm doing.</p>
  
  <p>I'll never need to access an individual element from the database - it will always be the entire grid loaded at once.</p>
  
  <p>Any thoughts on what might be the most efficient approach?</p>
