我有这段代码嵌入到我的 sql 中。出于某种原因，我看到每次我的最后一个 ELSE 块被执行。这是我的代码：

 IF REGEXP_LIKE (UPPER(V_TEMP_DEPT_1),
        'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG|FAC|AMU|LAB|WING|
          UNIT|SERV|AFT|CENT|CLIN|KLIN|ETHICS COM|EC|IRB') THEN
              V_DEPT_N    := V_TEMP_DEPT_1;
              V_ADDR_LINE1:= NULL;
      ELSE

      IF REGEXP_LIKE (UPPER(V_TEMP_DEPT_2),
      'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG|FAC|AMU|LAB|WING|
        UNIT|SERV|AFT|CENT|CLIN|KLIN|ETHICS COM|EC|IRB') THEN
            V_DEPT_N    := V_TEMP_DEPT_2;
            V_ADDR_LINE2:= NULL;
                    ELSE

      IF REGEXP_LIKE (UPPER(V_TEMP_DEPT_3),
          'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG|FAC|AMU|LAB|WING|
            UNIT|SERV|AFT|CENT|CLIN|KLIN|ETHICS COM|EC|IRB') THEN
              V_DEPT_N    := V_TEMP_DEPT_3;
              V_ADDR_LINE3:= NULL;
      ELSE

      IF REGEXP_LIKE (UPPER(V_TEMP_DEPT_4),
          'DEP|DPT$|ABT|DIP.|DIPART|AFDEL|AVDEL|AVD.|DIV|PGRD|PGP|PPG|FAC|AMU|LAB|WING|
            UNIT|SERV|AFT|CENT|CLIN|KLIN|ETHICS COM|EC|IRB') THEN
              V_DEPT_N    := V_TEMP_DEPT_4;
              V_ADDR_LINE4:= NULL;
      ELSE
              -- The below line always gets executed.
              V_DEPT_N:= NULL;

      END IF;
        END IF;
          END IF;
            END IF;

任何想法我做错了什么？
