使用DBMS_RANDOM.VALUE和按日期排序...的Oracle SQL

Question

我这是写在Oracle SQL下面的查询：

SELECT 
"P No","Name","Type","AID","Start","End","Day Ended","Worker","Team","Outcome" 
FROM 
(SELECT 
O_ASSESSMENTS.ASM_SUBJECT_ID as "P No", 
olm_bo.get_name(O_ASSESSMENTS.ASM_SUBJECT_ID,O_ASSESSMENTS.ASM_SUBJECT_IND) as "Name", 
O_QUESTION_SET_APPLICATIONS.QSA_DESC as "Type", 
O_ASSESSMENTS.ASM_ID as "AID", 
O_ASSESSMENTS.ASM_START_DATE as "Start", 
O_ASSESSMENTS.ASM_END_DATE as "End", 
TO_CHAR(O_ASSESSMENTS.ASM_END_DATE, 'Day') as "Day Ended", 
olm_bo.get_org_name(assessment_worker.RES_PARTY_OUN_ID) as "Worker", 
olm_bo.get_per_name(assessment_worker.RES_PARTY_ID) as "Team", 
olm_bo.get_ref_desc(O_ASSESSMENTS.ASM_OUTCOME,'ASM_OUTCOME') as "Outcome" 
FROM 
O_QUESTION_SET_APPLICATIONS, 
O_RESPONSIBILITIES assessment_worker, 
O_ASSESSMENTS 
WHERE 
(assessment_worker.RES_REC_ID(+)=O_ASSESSMENTS.ASM_ID AND assessment_worker.RES_REC_TYPE (+)='ASM' AND assessment_worker.RES_END_DATE IS NULL ) 
AND (O_QUESTION_SET_APPLICATIONS.QSA_ID=O_ASSESSMENTS.ASM_QSA_ID ) 
AND 
(olm_bo.get_org_name(assessment_worker.RES_PARTY_OUN_ID) = 'TEAM' 
    AND 
    olm_bo.get_ref_desc(O_ASSESSMENTS.ASM_OUTCOME,'ASM_OUTCOME') IN ('No Further Action') 
    AND 
    O_ASSESSMENTS.ASM_END_DATE Is Not Null 
    AND 
    O_QUESTION_SET_APPLICATIONS.QSA_ID IN ('TYPE1' ) 
    AND 
    O_ASSESSMENTS.ASM_END_DATE >= trunc(sysdate-7) 
) 
ORDER BY 
    dbms_random.value) 
WHERE ROWNUM <= 30 
ORDER BY "End" DESC 

基本上它是返回已在过去一周被关闭关闭评估，并且dbms_random.value返回30个随机记录。不过，我还想按结束日期的降序对最终输出进行排序。然而，这似乎并没有工作，我想这与dbms_random.value有关。我已经试过把“end”放在dms_random.value上面，但是看起来并不工作 - 两个代码的例子都会运行，但是它们看起来并没有按日期顺序返回。不知道我是否失去了任何盲目显而易见的东西，但任何想法都将非常感激。

谢谢。

编辑：

奇怪的是，这个工程：

SELECT * FROM 
(SELECT 
    O_ASSESSMENTS.ASM_SUBJECT_ID as "P_No", 
    olm_bo.get_name(O_ASSESSMENTS.ASM_SUBJECT_ID,O_ASSESSMENTS.ASM_SUBJECT_IND) as "Name", 
    O_QUESTION_SET_APPLICATIONS.QSA_DESC as "Type", 
    O_ASSESSMENTS.ASM_ID as "AID", 
    O_ASSESSMENTS.ASM_START_DATE as "Start", 
    O_ASSESSMENTS.ASM_END_DATE as "End", 
TO_CHAR(O_ASSESSMENTS.ASM_END_DATE, 'Day') as "Day_Ended", 
    olm_bo.get_org_name(assessment_worker.RES_PARTY_OUN_ID) as "Team", 
    olm_bo.get_per_name(assessment_worker.RES_PARTY_ID) as "Worker", 
    olm_bo.get_ref_desc(O_ASSESSMENTS.ASM_OUTCOME,'ASM_OUTCOME') as "Outcome" 
FROM 
    O_QUESTION_SET_APPLICATIONS, 
    O_RESPONSIBILITIES assessment_worker, 
    O_ASSESSMENTS 
WHERE 
    (assessment_worker.RES_REC_ID(+)=O_ASSESSMENTS.ASM_ID AND assessment_worker.RES_REC_TYPE(+)='ASM' AND assessment_worker.RES_END_DATE IS NULL ) 
    AND (O_QUESTION_SET_APPLICATIONS.QSA_ID=O_ASSESSMENTS.ASM_QSA_ID ) 
    AND 
    (nvl(olm_bo.get_org_name(assessment_worker.RES_PARTY_OUN_ID),'NULL') = 'TEAM' 
    AND 
    nvl(olm_bo.get_ref_desc(O_ASSESSMENTS.ASM_OUTCOME,'ASM_OUTCOME'),'NULL') IN ('CONTACT ONLY - all actions complete','No Further Action' ) 
    AND 
    O_ASSESSMENTS.ASM_END_DATE Is Not Null 
    AND 
    nvl(O_QUESTION_SET_APPLICATIONS.QSA_ID,'NULL') IN ('TYPE1') 
    AND 
    O_ASSESSMENTS.ASM_END_DATE >= trunc(sysdate-7) 
) 
ORDER BY 
    dbms_random.value) 
WHERE ROWNUM <= 30 
ORDER BY "End" DESC 

所以不知道是否有在原来代码中的故障，或者说已经改变，使其工作...

敲开一个简单的例子工作正常，所以明确地检查你的SQL，由于你做了可能的编辑，在帖子中似乎有问题。我已经缩短了它的清晰度。

SELECT * 
FROM 
    (
    SELECT 
     "P No","Name","Type","AID","Start" 
     ,"End","Day Ended","Worker","Team","Outcome" 
    FROM O_ASSESSMENTS 
    WHERE 
    O_ASSESSMENTS.ASM_END_DATE Is Not Null 
    AND 
     nvl(O_QUESTION_SET_APPLICATIONS.QSA_ID,'NULL') IN ('TYPE1') 
    AND 
    O_ASSESSMENTS.ASM_END_DATE >= trunc(sysdate-7) 
    ) 
ORDER BY 
dbms_random.value 

) 
WHERE ROWNUM <= 30 
ORDER BY "End" DESC 

最终的右括号什么都不匹配，所以有些东西不太对。示例I扔在一起：

select a.test_id 
from 
(
select test_id 
from tbl_Test 
order by dbms_random.value 
) a 
where rownum <= 10 
order by a.test_id 

从外部排序中指定的顺序从示例表中取回10个随机ID。
