Try this

Код:

format(query, sizeof(query), "SELECT `ID` FROM `friends` WHERE (`friend1` = '%d' AND `friend2` = '%d') OR (`friend1` = '%d' AND `friend2` = '%d')", PlayerData[playerid][pID], PlayerData[i][pID], PlayerData[i][pID], PlayerData[playerid][pID]);

If this won't work give more code and mysql log.
