Answer 1

SELECT DISTINCT(EMP.EMPLOYEEID), 
    EMP.EMPLOYEECODE, 
    EMP.EMPLOYEENAME, 
    EMP.HOMEADDRESS, 
    DESIG.DESIGNATIONNAME 
    FROM HRM_EMPLOYEE EMP, 
    COM_DESIGNATION DESIG, 
    COM_DEPARTMENT DEPT, 
    COM_COMPANY COMP, 
    HRM_EMPLOYEEDEPARTMENTS EMPDEPT, 
    USR_USERS USRS 
    WHERE EMP.EMPLOYEEID = EMPDEPT.EMPLOYEEID AND 
    EMP.DESIGNATIONID = DESIG.DESIGNATIONID AND 
    DESIG.DEPARTMENTID = EMPDEPT.DEPARTMENTID AND 
    ( 
    (EMP.STATUS IN (1, 2) and :status = 0) 
     or :status <> 0 --This will not filter your status, as I expect you want it to do so 
    ) 

Answer 2

당신은 테이블 식으로 CASE 문을 가질 수 없습니다 (하지 않는 한 아마도 중첩 테이블 유형을 사용하는 경우). 그러나 왜 그렇게 복잡한가?

EMP.STATUS IN (SELECT STAT STAT 
    FROM 
     (
     CASE 
     When (:status = 0) THEN 
     SELECT 1 STAT FROM dual 
     UNION ALL 
     SELECT 2 STAT FROM dual 
     else 
     Select :status STAT from dual 
     end 
    ) 
     xx 
    ) 

쓰기이 : 대신이의

(EMP.STATUS IN (1, 2) AND :status = 0) OR 
(EMP.STATUS = :status)
