将两个SQL查询合并为一个

Question

Please forgive me if this appears a bit vague and if my terminologies are incorrect. I'm an associate/junior level network engineer with very limited SQL querying experience. With that aside here is what I'm dealing with;

I'm trying to create a filter in Goldmine (CMS/CRM) that filters results by the variables specified below.

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)

I need to incorporate the following but have no idea where it is safe to the expression to the above.

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

Any advice will be greatly appreciated.

Thanks,

Rob

I believe it should be fine to put it at the end, before the ORDER BY , where a WHERE clause is normally placed:

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
