Code:

if(strcmp(option, "delete", true) == 0)
		{
			new id, query[50];
			if(sscanf(params, "s[6]d", option, id))
			{
				SendClientMessage(playerid, COLOR_GREY, "Usage: {FFFFFF}/edithouse delete [ID]");
				return 1;
			}
			HouseInfo[id][server_ID] = id;
			DestroyPickup(HouseInfo[id][Pickup]);
			DestroyDynamic3DTextLabel(HouseInfo[id][Label]);
			format(str, sizeof(str), "You've successfully deleted house id %d", HouseInfo[id][server_ID]);
			SendClientMessage(playerid, COLOR_GREY, str);
			format(query, sizeof(query), "DELETE FROM houses WHERE server_ID='%i'", HouseInfo[id][server_ID]);
			mysql_function_query(dbhandle, query , true, "", "");
			return 1;
		}

In sql it does delete.
