以下是我的查询：

UPDATE DSOPI_PERSON_ADDR_RULE ADDR
SET ADDR.DEPT_NAME =
  CASE
    WHEN regexp_like (UPPER(addr.src_address_line1),     'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
    AND ADDR.ORG_NAME IS NOT NULL
    THEN ADDR.SRC_ADDRESS_LINE1
    WHEN regexp_like (UPPER(addr.src_address_line2), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
    AND ADDR.ORG_NAME IS NOT NULL
    THEN ADDR.SRC_ADDRESS_LINE2
    WHEN regexp_like (UPPER(addr.src_address_line3), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
    AND ADDR.ORG_NAME IS NOT NULL
    THEN ADDR.SRC_ADDRESS_LINE3
    WHEN regexp_like (UPPER(addr.src_address_line4), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
    AND ADDR.ORG_NAME IS NOT NULL
    THEN ADDR.SRC_ADDRESS_LINE4
    ELSE NULL
 END;

我想做的是，当案例条件为真时，我想让相应的地址行为 NULL。有没有办法用这段代码实现它？

因此，如果第一个 WHEN 条件为真，您想将 src_address_line1 设置为 NULL，等等？在这种情况下，我会这样做：

UPDATE DSOPI_PERSON_ADDR_RULE ADDR

SET 
addr.src_address_line1 = 
CASE WHEN regexp_like (UPPER(addr.src_address_line1), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG') 
AND ADDR.ORG_NAME IS NOT NULL 
THEN NULL ELSE addr.src_address_line1 END, 

addr.src_address_line2 = 
CASE WHEN regexp_like (UPPER(addr.src_address_line2), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG') 
AND ADDR.ORG_NAME IS NOT NULL 
THEN NULL ELSE addr.src_address_line2 END, 

addr.src_address_line3 = 
CASE WHEN regexp_like (UPPER(addr.src_address_line3), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG') 
AND ADDR.ORG_NAME IS NOT NULL 
THEN NULL ELSE addr.src_address_line3 END, 

addr.src_address_line4 = 
CASE WHEN regexp_like (UPPER(addr.src_address_line4), 'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG') 
AND ADDR.ORG_NAME IS NOT NULL 
THEN NULL ELSE addr.src_address_line4 END;

CASE您可以选择为每个地址字段添加附加语句：

代码是重复的，但这允许您在满足条件时将地址行设置为空。

UPDATE DSOPI_PERSON_ADDR_RULE ADDR
SET ADDR.DEPT_NAME =
   CASE
      WHEN regexp_like (UPPER(addr.src_address_line1),
         'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
         AND ADDR.ORG_NAME IS NOT NULL
         THEN ADDR.SRC_ADDRESS_LINE1
      WHEN regexp_like (UPPER(addr.src_address_line2), 
         'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
         AND ADDR.ORG_NAME IS NOT NULL
         THEN ADDR.SRC_ADDRESS_LINE2

         THEN ADDR.SRC_ADDRESS_LINE4
      ELSE NULL
   END
   , ADDR.SRC_Address_Line1 =
        CASE

              'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
              AND ADDR.ORG_NAME IS NOT NULL
              THEN NULL
           ELSE ADDR.SRC_Address_Line1
        END

              AND ADDR.ORG_NAME IS NOT NULL
              THEN NULL
           ELSE ADDR.SRC_Address_Line2
        END
   , ADDR.SRC_Address_Line3 =
        CASE
           WHEN regexp_like (UPPER(addr.src_address_line3),      
              'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG')
