Question

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?

Answer 1

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
