Oracle SQL - 帶Rtrim和Regexp的Listagg - 重複仍然存在

我正在使用LISTAGG與RTRIM和REGEXP_REPLACE創建測試分數的逗號分隔列表，但除去重複項。Oracle SQL - 帶Rtrim和Regexp的Listagg - 重複仍然存在

問題是仍然有重複。

下面給出的數據直接來自SORTEST表格。（SELECT * FROM SORTEST WHERE SORTEST_PIDM ='260670'）我確實消除了我沒有使用的列。

Q1：爲什麼會有重複？

問題二：如何消除它們？

我認爲這可能與兩組A01-A05得分有關。它只發生在擁有多組A分數的人身上。

SELECT DISTINCT 
SP.SPRIDEN_ID AS "STUDENT_ID", 
t2.sortest_pidm, 
SP.SPRIDEN_LAST_NAME AS "LAST", 
SP.SPRIDEN_FIRST_NAME AS "FIRST", 
RTRIM(
REGEXP_REPLACE(
(
listagg ((T2.SORTEST_TESC_CODE || '-' || T2.SORTEST_TEST_SCORE), ', ') 
WITHIN GROUP (ORDER BY SP.SPRIDEN_ID) 
OVER (PARTITION BY SP.SPRIDEN_ID)), 
      '([^-]*)(-\1)+($|-)', 
      '\1\3'), 
     '-') TEST 
FROM 
SPRIDEN SP 
left outer join SPBPERS B on SP.spriden_pidm = b.spbpers_pidm 
JOIN SORTEST T2 ON T2.SORTEST_PIDM = SP.SPRIDEN_PIDM 
WHERE 
SP.SPRIDEN_CHANGE_IND IS NULL 
AND B.SPBPERS_DEAD_IND IS NULL 
AND B.SPBPERS_CONFID_IND <> 'Y' 
AND T2.SORTEST_TADM_CODE IS NULL 
AND 
T2.SORTEST_TESC_CODE IN ('CM1B', 'CM2B', 'CR1B', 'CW1B', 'A01B', 'A02B', 'A03B', 'A04B', 
         'A05B', 'S01B', 'S02B', 'S95B', 'DSPW', 'DSPR', 'DSPM') 
         AND sP.spriden_change_ind is null 
AND SP.SPRIDEN_ID IN ('A00154876')

數據請注意，SORTEST_PIDM = SPRIDEN_PIDM：雖然因爲我在尋找得分LIKE '％A'

CODE這是沒有道理給我。我沒有包含SPRIDEN ID或名稱，因爲我想簡化數據部分。

+--------------+-------------------+-------------------+--------------------+ | SORTEST_PIDM | SORTEST_TESC_CODE | SORTEST_TEST_DATE | SORTEST_TEST_SCORE | +--------------+-------------------+-------------------+--------------------+ | | | | | | 260670 | A01 | 1-Mar-12 | 20 | | 260670 | A01 | 1-Oct-12 | 22 | | 260670 | A01B | 9-Jan-13 | 22 | | 260670 | A02 | 1-Mar-12 | 19 | | 260670 | A02 | 1-Oct-12 | 19 | | 260670 | A02B | 5-Jun-12 | 19 | | 260670 | A03 | 1-Mar-12 | 21 | | 260670 | A03 | 1-Oct-12 | 19 | | 260670 | A03B | 5-Jun-12 | 21 | | 260670 | A04 | 1-Mar-12 | 23 | | 260670 | A04 | 1-Oct-12 | 22 | | 260670 | A04B | 5-Jun-12 | 23 | | 260670 | A05 | 1-Mar-12 | 21 | | 260670 | A05 | 1-Oct-12 | 21 | | 260670 | A05B | 5-Jun-12 | 21 | | 260670 | DSPM | 5-Jun-12 | 4 | | 260670 | DSPR | 5-Jun-12 | 4 | | 260670 | DSPW | 5-Jun-12 | 4 | +--------------+-------------------+-------------------+--------------------+

結果：

這是我想要的結果：

@mto謝謝。我能夠得到我需要的結果。我甚至不需要Regexp！ –
