拋出SQL錯誤4145

Question

我試圖讓所有帳戶持有者獲得積極的期末餘額。只有最後一個積極的收盤餘額是有趣的，所以我想擁有我的表的最大ID。我想下面的

SELECT DA.HOLDER, FAB.AMOUNT 
    FROM ACCOUNTS_TABLE DA 
     JOIN BALANCE_TABLE FAB ON FAB.ACCOUNT_ID = DA.ID 
    WHERE FAB.IS_CLOSING = 1 AND FAB.AMOUNT > 0 
    GROUP BY DA.HOLDER 
    HAVING MAX(FAB.DATE); 

但是，當我嘗試執行此查詢，我得到以下錯誤：

Error: An expression of non-boolean type specified in a context where a condition is expected, near ';'. SQLState: S0001 ErrorCode: 4145

有什麼不對？

這是「最偉大的正每組」的問題，他們通常與窗函數解決：

SELECT holder, amount, fab_date 
FROM (
    SELECT da.holder, 
     fab.amount, 
     fab.date as fab_date, 
     max(fab.date) OVER (PARTITION BY da.holder) as max_date 
    FROM accounts_table da 
     JOIN balance_table fab ON fab.account_id = da.id 
    WHERE fab.is_closing = 1 
    AND fab.amount > 0 
) 
WHERE fab_date = max_date;
