Thanks for your help, I've stored a 2-dimensional array in Postgres,
inserted like this:
{{1,1,3},{2,2,1},{3,1,2}}
But I'm having trouble retrieving it from Java. My jdbc driver is loaded
fine and I'm connecting to the database, but I don't know how to get from a
java.sql Array to an int[] array in Java. I'm using this piece of code to
pull the data from the ResultSet:
Array categoryArray = rs.getArray("category").getArray();
But I don't know what to do with this. I want to end up with an int[] array.
Can anyone suggest something?
Thanks a lot,
