return more than 1 value after THEN statement used with CASE

Following is my query:

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;

What I would like to do is, when the case condition is true I would like to make the respective address lines NULL. Is there any way to achieve it with this code?

One option you have is to add additional CASE statements for each address field:

The code is duplicated, but this allows you to set the address lines to null when the condition is met.

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
   , 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;

So you would like to set src_address_line1 NULL if the first WHEN condition is true, and so on? In this case I'd do this: 

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;
