GStylez MYSQL plugin:
Top of the script:

pawn Код:

new
        id[MAX_PLAYERS],
        belongsto[MAX_PLAYERS],
        contactname[MAX_PLAYERS],
        contactnumber[MAX_PLAYERS];

Somewhere else:

pawn Код:

new query[128], playername[MAX_PLAYER_NAME], result[128];
GetPlayerName(playerid, playername, sizeof(playername));
format(query, sizeof(query), "SELECT * FROM `yourtable` WHERE `belongs_to` = '%s'", playername); // I assume belongs_to is the field of the guy who's typing the command to view his contact list.
mysql_query(query);
mysql_store_result();
if(mysql_fetch_row_format(result))
{
     sscanf(result, "is[24]s[24]i", id[playerid], belongsto[playerid], contactname[playerid], contactnumber[playerid]);
}
mysql_free_result();
