我加入了5个表，得到了最终结果，这是下面给出的查询。

SELECT *

例如，给出4条结果行：

但是ACCOUNTNO包含NULL。 我想过滤掉ACCOUNTNO中包含的NULL值，所以我给了WHERE ACCOUNTNO != NULL，但结果是我没有值，空行

CUSTADDRESSID   ACCOUNTNO   ADDRESSTYPE ADDRESSLINE1    ADDRESSLINE2    ADDRESSLINE3    CITY    STATE   COUNTRY ZIP1    ISACTIVE_ADDRESS    ISCOMMUNICATION_ADDRESS ORGANISATIONNAME    DATEOFINCORPORATION PANCARDNUMBER   ORGANIZATIONTYPEID  CUSTMAILID  EMAILTYPE   EMAILADDRESS    ISACTIVE_MAILID ISCOMMUNICATION_MAILID  LOGINID USERNAME    PASSWORD    LAST_LOGINDATE  LAST_PWD_MODIFIEDDATE   CURRENT_PWD_EXPIRYDATE  PWD_ATTEMPTS_COUNT  PINNUMBER   ISLOCKED    THEMES  LANGUAGES   STATUSID    USERTYPEID  ROLENAME    SQ_ATTEMPTCOUNT SQ_LOCKOUTTIME  CUSTPHONEID PHONETYPE   PHONENUMBER EXTENTION   ISACTIVE_PHONES ISCOMMUNICATION_PHONES

需要帮助。谢谢。

您可以使用IS检查空值

WHERE ACCOUNTNO IS NOT NULL

这不能回答OP的问题，但是，这里不需要使用子查询，也不需要使用巨大的GROUP BY子句。只需使用DISTINCT（Using DISTINCT with SELECT）：

SELECT DISTINCT
       O.CUSTADDRESSID,
       O.ACCOUNTNO,
       O.ADDRESSTYPE,
       O.ADDRESSLINE1,
       O.ADDRESSLINE2,
       O.ADDRESSLINE3,
       O.CITY,
       O.STATE,
       O.COUNTRY,
       O.ZIP1,
       O.ISACTIVE AS ISACTIVE_ADDRESS,
       O.ISCOMMUNICATION AS ISCOMMUNICATION_ADDRESS,
       D.ORGANISATIONNAME,
       D.DATEOFINCORPORATION,
       D.PANCARDNUMBER,
       D.ORGANIZATIONTYPEID,
       P.CUSTMAILID,
       P.EMAILTYPE,
       P.EMAILADDRESS,
       P.ISACTIVE AS ISACTIVE_MAILID,
       P.ISCOMMUNICATION AS ISCOMMUNICATION_MAILID,
       Q.LOGINID,
       Q.USERNAME,
       Q.PASSWORD,
       Q.LAST_LOGINDATE,
       Q.LAST_PWD_MODIFIEDDATE,
       Q.CURRENT_PWD_EXPIRYDATE,
       Q.PWD_ATTEMPTS_COUNT,
       Q.PINNUMBER,
       Q.ISLOCKED,
       Q.THEMES,
       Q.LANGUAGES,
       Q.STATUSID,
       Q.USERTYPEID,
       Q.ROLENAME,
       Q.SQ_ATTEMPTCOUNT,
       Q.SQ_LOCKOUTTIME,
       R.CUSTPHONEID,
       R.PHONETYPE,
       R.PHONENUMBER,
       R.EXTENTION,
       R.ISACTIVE AS ISACTIVE_PHONES,
       R.ISCOMMUNICATION AS ISCOMMUNICATION_PHONES
FROM ISSUER.TOLLPLUS.TP_CUSTOMER_ADDRESSES O
     FULL OUTER JOIN ISSUER.TOLLPLUS.TP_CUSTOMER_BUSINESS D ON O.ACCOUNTNO = D.ACCOUNTNO
     FULL OUTER JOIN ISSUER.TOLLPLUS.TP_CUSTOMER_EMAILS P ON D.ACCOUNTNO = P.ACCOUNTNO
     FULL OUTER JOIN ISSUER.TOLLPLUS.TP_CUSTOMER_LOGINS Q ON P.ACCOUNTNO = Q.ACCOUNTNO
     FULL OUTER JOIN ISSUER.TOLLPLUS.TP_CUSTOMER_PHONES R ON Q.ACCOUNTNO = R.ACCOUNTNO
ORDER BY O.ACCOUNTNO;

此外，您是否由于使用FULL OUTER JOIN而遇到问题？我想知道如果您使用NULL，您的INNER JOIN问题行是否会消失？？
