「錯誤：在JOIN的任一側都找不到字段'[編輯] .field_id'」，Google BigQuery

Question

作爲Google BigQuery平臺的初學者，我發現它與它的語法幾乎類似於MySql。但是，我收到一個問題，在我的查詢中沒有在我正在執行的Inner Join的任一側找到一列。

以下示例查詢：

SELECT 
    base_account.random_table_name_transaction.context_id, 
    base_account.random_table_name_transaction.transaction_id, 
    base_account.random_table_name_transaction.meta_recordDate, 
    base_account.random_table_name_transaction.transaction_total, 
    base_account.random_table_name_transaction.view_id, 
    base_account.random_table_name_view.user_id, 
    base_account.random_table_name_view.view_id, 
    base_account.random_table_name_view.new_vs_returning, 
    base_account.random_table_name_experience.view_id, 
    base_account.random_table_name_experience.experienceId, 
    base_account.random_table_name_experience.experienceName, 
    base_account.random_table_name_experience.variationName, 
    base_account.random_table_name_experience.iterationId, 
    base_account.random_table_name_experience.isControl 
FROM 
    [base_account.random_table_name_transaction] transactiontable 
INNER JOIN 
    base_account.random_table_name_view viewtable 
ON 
    transactiontable.view_id=viewtable.view_id 
INNER JOIN 
    [base_account.random_table_name_experience] experiencetable 
ON 
    viewtable.view_id=experiencetable.view_id 
WHERE experiencetable.experienceId = 96659 or experiencetable.experienceId = 96660 

在這種情況下，當我的BigQuery平臺內運行，查詢運行的幾秒鐘後，我返回了一個錯誤： "Error: Field 'base_account.random_table_name_experience.experienceId' not found on either side of the JOIN"。

但是，當我運行相同的查詢但是我執行SELECT *查詢時，它確實執行並返回我期望的數據。

我的語法有些缺失，爲什麼它失敗？我可以確認每個列我都試圖返回確實存在於每個受尊敬的表中。

請確保使用standard SQL進行查詢，以避免使用遺留SQL出現一些令人驚訝的別名規則，並獲取更多信息性錯誤消息。您所查詢的是：

#standardSQL 
SELECT 
    base_account.random_table_name_transaction.context_id, 
    base_account.random_table_name_transaction.transaction_id, 
    base_account.random_table_name_transaction.meta_recordDate, 
    base_account.random_table_name_transaction.transaction_total, 
    base_account.random_table_name_transaction.view_id, 
    base_account.random_table_name_view.user_id, 
    base_account.random_table_name_view.view_id, 
    base_account.random_table_name_view.new_vs_returning, 
    base_account.random_table_name_experience.view_id, 
    base_account.random_table_name_experience.experienceId, 
    base_account.random_table_name_experience.experienceName, 
    base_account.random_table_name_experience.variationName, 
    base_account.random_table_name_experience.iterationId, 
    base_account.random_table_name_experience.isControl 
FROM 
    `base_account.random_table_name_transaction` transactiontable 
INNER JOIN 
    base_account.random_table_name_view viewtable 
ON 
    transactiontable.view_id=viewtable.view_id 
INNER JOIN 
    `base_account.random_table_name_experience` experiencetable 
ON 
    viewtable.view_id=experiencetable.view_id 
WHERE experiencetable.experienceId = 96659 OR experiencetable.experienceId = 96660; 

請注意，只有我做出的改變是把#standardSQL在啓動（啓用標準SQL），並逃避反引號與而非括號中的表名。
