I have also weird results:
I access data by ID, which is a primary key in the table.
Some times (again, very random behaviour) I get 4 rows back
(instead of just 1) and the data I get is always
1275749989
This happens with random IDs.
the code to check this is:
[..]
ResultSet rs = ps1.executeQuery();
boolean c = false;
while (rs.next()) {
int g = rs.getInt(2);
if (c) {
// this shouldn't happen, because I'm selecting by ID, but it happens!
System.out.println(m + " " + g);
}
c = true;
}
