    STUDENTS.LAST_NAME as "lastname", 
    STUDENTS.STUDENT_NUMBER as "idNumber", 
    STUDENTS.ENROLL_STATUS as "status", 
    STUDENTS.SCHOOLID as "school", 
    STUDENTS.CLASSOF as "gradyear", 
    U_DEF_EXT_STUDENTS.GSUITEEMAILADDRESS as "email" 
from U_DEF_EXT_STUDENTS U_DEF_EXT_STUDENTS, 
    STUDENTS STUDENTS 
where U_DEF_EXT_STUDENTS.STUDENTSDCID=STUDENTS.DCID 
     and STUDENTS.SCHOOLID =1992 
     and STUDENTS.ENROLL_STATUS =0 

Answer 1

您可以指定1到狀態

SELECT STUDENTS.FIRST_NAME as "firstname", 
     STUDENTS.LAST_NAME as "lastname", 
     STUDENTS.STUDENT_NUMBER as "idNumber", 
     1 as "status", -- assign 1 to status 
     STUDENTS.SCHOOLID as "school", 
     STUDENTS.CLASSOF as "gradyear", 
     U_DEF_EXT_STUDENTS.GSUITEEMAILADDRESS as "email" 
    FROM U_DEF_EXT_STUDENTS U_DEF_EXT_STUDENTS 
INNER JOIN STUDENTS STUDENTS 
    ON U_DEF_EXT_STUDENTS.STUDENTSDCID = STUDENTS.DCID 
WHERE STUDENTS.SCHOOLID = 1992 
    AND STUDENTS.ENROLL_STATUS = 0
