Question

code:

public int getLastGotKill()
{
    Connection con = null;
    int last_pvp_time = 0;
    try
    {
        con = L2DatabaseFactory.getInstance().getConnection(false);
        PreparedStatement statement;
        statement = con.prepareStatement("select last_got_kill from characters where obj_Id=?");
        statement.setInt(1, getObjectId());

        ResultSet rset = statement.executeQuery();
        while(rset.next())
        {
            last_pvp_time = rset.getInt("last_got_kill");
            _log.info("last pvp time is : " + last_pvp_time);
        }
        rset.close();
        rset = null;
        statement.close();
        statement = null;
    }
    catch(Exception e)
    {
        if(Config.ENABLE_ALL_EXCEPTIONS)
            e.printStackTrace();
    }
    finally
    {
        CloseUtil.close(con);
        con = null;
    }
    return last_pvp_time;
}

so when i call this function it gets into the while loop inside the try{} but when i try to print the value of the selected column it prints 0 and so it returns 0…

last_got_kill column in characters table is a bigint(20) type

i can see that there is a number in that column ex. 4294967295 which are

But why do i always get 0 back?

Answer 1

you have to get a long instead . as your number exceeds int range.

Integer.MAX_VALUE is 2147483647 which is surely less than 4294967295
Long.MAX_VALUE however is 9223372036854775807 seems to suit your case.

   long last_pvp_time = rset.getLong("last_got_kill");

should work.
