所以我有類似的請求

WITH customers_in_usa AS (
        SELECT 
           customerName, state
        FROM
           customers
        WHERE
           country = 'USA'
    ) SELECT 
        customerName
    FROM
        customers_in_usa
    WHERE
        state = 'CA'
    ORDER BY customerName;

但是在寫它時我發現了一個錯誤：「WITH 在這個位置上的輸入無效」error_picture。你能幫我理解這段程式碼有什麼問題嗎？
