如何INNER JOIN多個表？

Question

我有4張桌子，看起來像這樣：

dog
ID
<numerous fields>
vetID

client
ID
<again, numerous fields I don't think are relevant>

vet
ID
<More irrelevant fields>

dogclient
ID
DogID
ClientID

我正在嘗試從所有這些表中獲取特定狗的ID的所有信息。 我在PDO准備好的語句中嘗試了此查詢

SELECT dog.*, client.*, vet.* 
FROM dogclient 
INNER JOIN client ON dogClient.ClientID = client.ID 
INNER JOIN dog ON dogclient.DogID = dog.ID 
INNER JOIN dog.vetID = vet.ID 
WHERE dogclient.dogID = :id

結果是查詢中的語法錯誤：

'.ID WHERE dogclient.dogID = '4''

我怎樣才能解決這個問題？

Answer 1

SELECT dog.*, client.*, vet.* FROM dogclient 
    INNER JOIN client ON dogClient.ClientID = client.ID 
    INNER JOIN dog ON dogclient.DogID = dog.ID 
    INNER JOIN vet ON dog.vetID = vet.ID 
    WHERE dogclient.dogID = :id

您在最后一個內部聯接中缺少vet表
