將兩個SQL查詢合並為一個

Question

如果這看起來有點含糊，如果我的用語不正確，請原諒我。 我是一名初級/初級網絡工程師，具有非常有限的SQL查詢經驗。 除了這些，我正在處理的是什么？

我正在嘗試在Goldmine（CMS / CRM）中創建一個過濾器，該過濾器通過下面指定的變量過濾結果。

WHERE c1.U_COMPANY > ' ' AND  c1.U_CONTACT > ' ' AND  
     (c1.U_COUNTRY <> 'SOUTH AFRICA') AND  
     (c1.U_CONTACT NOT LIKE '%MANAGER%' OR c1.U_CONTACT IS NULL) AND     
     (c1.U_KEY1 NOT LIKE '%ARCHIVE%' OR c1.U_KEY1 IS NULL) AND 
     (c1.U_KEY1 NOT LIKE '%DOCUMENT%' OR c1.U_KEY1 IS NULL) AND 
     (c1.U_KEY1 NOT LIKE '%SUPPLIER%' OR c1.U_KEY1 IS NULL) AND  
     (c1.U_KEY1 NOT LIKE '%OTHER%' OR c1.U_KEY1 IS NULL) AND
     (c1.U_KEY1 NOT LIKE '%TENANT%' OR c1.U_KEY1 IS NULL)

我需要合並以下內容，但不知道上面的表達在哪里比較安全。

SELECT C1.*
FROM FMBSM.DBO.CONTACT1 C1
INNER JOIN (
    SELECT DISTINCT ACCOUNTNO
    FROM FMBSM.DBO.CONTSUPP
    WHERE (
            CONTSUPP.RECTYPE = 'P'
            AND CONTSUPP.CONTACT = 'E-mail Address'
            )
    ) CS
    ON CS.AccountNo = C1.AccountNo
ORDER BY C1.CONTACT

任何建議將不勝感激。

謝謝，

我認為應該將其放在通常放置WHERE子句的ORDER BY之前的末尾：

SELECT C1.*
FROM FMBSM.DBO.CONTACT1 C1
INNER JOIN (
    SELECT DISTINCT ACCOUNTNO
    FROM FMBSM.DBO.CONTSUPP
    WHERE (
            CONTSUPP.RECTYPE = 'P'
            AND CONTSUPP.CONTACT = 'E-mail Address'
            )
    ) CS
    ON CS.AccountNo = C1.AccountNo
WHERE c1.U_COMPANY > ' ' AND  c1.U_CONTACT > ' ' AND  
     (c1.U_COUNTRY <> 'SOUTH AFRICA') AND  
     (c1.U_CONTACT NOT LIKE '%MANAGER%' OR c1.U_CONTACT IS NULL) AND     
     (c1.U_KEY1 NOT LIKE '%ARCHIVE%' OR c1.U_KEY1 IS NULL) AND 
     (c1.U_KEY1 NOT LIKE '%DOCUMENT%' OR c1.U_KEY1 IS NULL) AND 
     (c1.U_KEY1 NOT LIKE '%SUPPLIER%' OR c1.U_KEY1 IS NULL) AND  
     (c1.U_KEY1 NOT LIKE '%OTHER%' OR c1.U_KEY1 IS NULL) AND
     (c1.U_KEY1 NOT LIKE '%TENANT%' OR c1.U_KEY1 IS NULL)
ORDER BY C1.CONTACT
