無法執行查詢

Question

我試圖執行SQL查詢，但得到了「缺少右括號」錯誤：

((SELECT CUST_ACCT 
    FROM CUSTMASTER 
    WHERE SITE_ID IN (SELECT SITE_ID FROM HOUSEMASTER WHERE FTAX=1)) 
    AND 
(SELECT CUST_ACCT 
    FROM CUSTMASTER 
    WHERE SITE_ID IN (SELECT SITE_ID FROM HOUSEMASTER WHERE MGT=1))) 

我覺得像括號內適當的檢查。請讓我知道缺少什麼？

Answer 1

它看起來像你試圖通過增加它們之間的and運營商獲得來自兩個不同的查詢結果爲一體。這不起作用。您可以使用union查詢，但它看起來可以簡化爲下面的查詢。

也許這就是你真正想要的？

SELECT CUST_ACCT 
FROM CUSTMASTER 
WHERE SITE_ID IN (
    SELECT SITE_ID 
    FROM HOUSEMASTER 
    WHERE FTAX=1 OR MGT=1 
) 

Answer 2

我認爲必須UNION：

((SELECT CUST_ACCT 
    FROM CUSTMASTER 
    WHERE SITE_ID IN (SELECT SITE_ID 
        FROM HOUSEMASTER 
        WHERE FTAX = 1)) 
    UNION 
    (SELECT CUST_ACCT 
    FROM CUSTMASTER 
    WHERE SITE_ID IN (SELECT SITE_ID FROM HOUSEMASTER WHERE MGT=1))) 

Answer 3

SELECT CUST_ACCT FROM CUSTMASTER WHERE SITE_ID 
IN (SELECT SITE_ID FROM HOUSEMASTER WHERE FTAX=1 or MGT=1) 

Answer 4

我不知道到底會導致您的描述不詳細。

試試這個，如果你嘗試比較就像select (true and false)：

選擇（（SELECT CUST_ACCT FROM CUSTMASTER WHERE SITE_ID IN（SELECT SITE_ID FROM舍監WHERE FTAX = 1））AND（SELECT CUST_ACCT FROM CUSTMASTER WHERE SITE_ID IN（SELECT SITE_ID FROM舍監WHERE MGT = 1）））
