Question

当我运行以下代码时，它会插入两行'07_%'，这些行最初在tlp中不存在，因为创建日期为'07-AUG-15'。

最初在GLOB我有600行是like '07_%'，那么这些行是如何插入的？

  INSERT INTO TLP
            (LASTNAME, FIRSTNAME, EMAIL1, USERID) 
SELECT NAME, GIVEN_NAME, MAIL, LOGIN
FROM   gLOB 
WHERE (( ( NOT EXISTS (SELECT EMAIL1 
                     FROM   TLP 
                     WHERE  GLOB.mail = TLP.email1 ) 
         AND GLOB.mail IS NOT NULL )
         AND GLOB.COUNTRY='GERMANY' )
        OR (( NOT EXISTS (SELECT userid
                         FROM   TLP
                         WHERE  GLOB.LOGIN = TLP.userid ) 
              )
  AND GLOB.COUNTRY='Germany'))
  and ( exists (select FIRSTNAME
                  from TLP
                  where (gLOB.name not like '07_%' AND 
                 GLOB.name not like 'TR_%' AND
                 GLOB.name not like 'ST_%' AND

                    GLOB.name is not null))

                 ));

我认为您正在尝试过滤掉07-AUG-15这样的值，但您喜欢的模式会显示07_%。它应该是

gal.name not like '07-%'

另外，你的最后一部分如下所示是没有意义的;相反，您应该在主查询WHERE子句中包含这些条件。

and ( exists (select FIRSTNAME
                  from TCPD_PERSONEL_COPY
                  where (gal.name not like '07_%' AND 
                 gal.name not like 'TR_%' AND
                 gal.name not like 'ST_%' AND
                  gal.name not like 'KB_%'  AND
                   gal.name not like 'HS_%'  AND
                    gal.name is not null))

您的SELECT应该是

SELECT SUBSTR(NAME, 1, 50),SUBSTR( GIVEN_NAME, 1, 50), DEPARTMENT, PHONE, SUBSTR(MAIL, 1, 100), SUBSTR(LOGIN, 1, 255), SYSDATE 
FROM   gal 
WHERE ( NOT EXISTS (SELECT EMAIL1 
                     FROM   TCPD_PERSONEL_COPY 
                     WHERE  GAL.mail = TCPD_PERSONEL_COPY.email1)

        OR NOT EXISTS (SELECT userid
                         FROM   TCPD_PERSONEL_COPY 
                         WHERE  gAL.LOGIN = TCPD_PERSONEL_COPY.userid))
AND GAL.mail IS NOT NULL AND GAL.COUNTRY='GERMANY'
AND (            gal.name not like '07_%' OR 
                 gal.name not like 'TR_%' OR
                 gal.name not like 'ST_%' OR
                  gal.name not like 'KB_%'  OR
                   gal.name not like 'HS_%'  OR
                    gal.name is not null);

如何插入两行？
