具有3个表的SQLite3内部联接

我尝试从3个具有内部联接的表中进行选择：

各表：

CREATE TABLE tracks (
'track_id' INTEGER PRIMARY KEY NOT NULL,
'name' TEXT NOT NULL,
'length' REAL DEFAULT '0.00',
'city' TEXT
);

CREATE TABLE heats (
'heat_id' INTEGER PRIMARY KEY NOT NULL,
'track_id' INTEGER UNSIGNED NOT NULL,
'heat_pos' INTEGER UNSIGNED NOT NULL,
'day_pos' INTEGER UNSIGNED NOT NULL,
'type' TEXT NOT NULL DEFAULT 'training',
'average' REAL,
'date' TEXT,
'comment' TEXT,
FOREIGN KEY ('track_id') REFERENCES tracks ('track_id')
);

CREATE TABLE laps (
'lap_id' INTEGER PRIMARY KEY NOT NULL,
'heat_id' INTEGER UNSIGNED NOT NULL,
'laptime' REAL UNSIGNED NOT NULL,
FOREIGN KEY ('heat_id') REFERENCES heats ('heat_id')
);

从两个表（圈数和热度）中选择信息时，其工作原理与我预期的一样：

select 
laps.lap_id, 
laps.laptime,
heats.heat_pos
from laps
inner join heats on laps.heat_id = heats.heat_id;

但现在我想从轨迹表中选择相应的轨迹名：

select 
laps.lap_id, 
laps.laptime,
heats.heat_pos,
tracks.name
from laps, tracks, heats
inner join heats on laps.heat_id = heats.heat_id and
inner join heats on tracks.track_id = heats.track_id;

这给了我以下错误：

不明确的列名：heats.heat\u pos

我完全迷路了，但我觉得这只是一个小错误。

---

有人知道我做错了什么吗？

谢谢，这正是我想要的。谢天谢地，我离这里不远：）

错误：模棱两可的列名：heats.heat\u pos

select 
laps.lap_id, 
laps.laptime,
heats.heat_pos,
tracks.name
from laps
inner join heats on laps.heat_id = heats.heat_id 
inner join tracks on tracks.track_id = heats.track_id;

select 
laps.lap_id, 
laps.laptime,
heats.heat_pos,
tracks.name
from laps
inner join heats on laps.heat_id = heats.heat_id
inner join heats on tracks.track_id = heats.track_id
ORDER BY laps.lap_id
