If I undestand you correctly you're looking for something like (in
pseudo-non-working-code):
int[] num = new int[]{1,2,3};
PreparedStatement ps = new PreparedStatement(
"SELECT * FROM items WHERE id IN ?");
ps.setArray(num);
ps.executeQuery();
If this is the case, then I'm pretty sure your answer's no. I've wanted
this a few times and haven't found anything. Your best answer is what
Andreas suggested.
cheers, Pete
