public OnPlayerConnect(playerid)
{
    new query[128], pname[MAX_PLAYER_NAME];
    GetPlayerName(playerid, pname, MAX_PLAYER_NAME);
    mysql_format(MySQL, query, sizeof(query), "SELECT * FROM `players` WHERE `Name` = '%e' LIMIT 1", pname);
    mysql_pquery(MySQL, query, "OnPlayerDataLoaded", "d", playerid);
    return 1;
}
 
public OnPlayerDataLoaded(playerid)
{
    //Query processed, you can now execute cache functions (like cache_get_row) here.
    new NumRows = cache_num_rows();
    printf("There are %d players with the same name.", NumRows);
