Question

我必须对字段中每一行的可能值进行描述我不必展示BASE类。

    SELECT A.COD_PUNTO, 
wm_concat(SUBSTR(C.DESCARDPRFCFR, 22, 10)) AS LIST
FROM FR_VALID_PROF A 
    INNER JOIN PUN B  
        ON A.COD_PUNTO = B.COD_PUNTO
    INNER JOIN DANAFR C 
        ON A.CODPRF = C.CARDPRFCFR
GROUP BY A.COD_PUNTO

我的结果是：

COD_PUNTO  |  LIST
---------------------
0          | BASE, SUNDAY
1          | BASE, SUNDAY, ORANGE, ORANGE
2          | BASE, BASE, SUNDAY, SUNDAY, ORANGE, ORANGE, ORANGE

但是我想要

COD_PUNTO  |  LIST
---------------------
0          | SUNDAY
1          | SUNDAY, ORANGE
2          | SUNDAY, ORANGE

我不能使用listagg，因为我使用过wm_concat。

Answer 1

使用子查询和DISTINCT子句：

SELECT COD_PUNTO, wm_concat(SUBSTR(DESCARDPRFCFR, 22, 10)) AS LIST
FROM (
  SELECT DISTINCT A.COD_PUNTO, C.DESCARDPRFCFR
  FROM FR_VALID_PROF A 
  INNER JOIN PUN B  
        ON A.COD_PUNTO = B.COD_PUNTO
  INNER JOIN DANAFR C 
        ON A.CODPRF = C.CARDPRFCFR
)
WHERE DESCARDPRFCFR <> 'BASE'
GROUP BY COD_PUNTO

将多个值从列连接到行，而不添加任何值
